Primarch fighting, while fun to see, isn't a very competitive thing to do as it'll usually tie up both Primarchs for the entire game without either of them dying. With that in mind this section is all about how Serras fares against other Primarchs mathhammer wise. Please note that all the various abilities are taken into account and the match-ups assume the Primarchs are the only ones involved in the fighting, so various abilities like Angron's "The Butcher's Nails" and Rampage do not provide any bonuses. As with Lorgar and Magnus, psychic powers are not accounted for, which is a slightly false choice given that Serras without witchery is like Bobby G without a Stick up his Ass. The things we do for 'fairness'….
Serras vs Angron
Serras: hits 3 times, wounds 2.1666 times and 1.08 after saves which FNP and IWND will take down to 0.648 at the start of next turn
Angron first round: hits 4.5 times, wounds 3.75 times and 1.562 after saves which IWND will take down to 1.219 at the start of next turn
Angron second round: hits 3 times, wounds 2.5 times and 1.0147 after saves which IWND will take down to 0.715 at the start of next turn
Angron comes in swinging with his high WS and S9 hits, but Serras' superior saves and high initiative allow her to take the victory, killing him before he can land the final blow in round 8. That FNP just does not compensate for the missing wound.
Serras vs Fulgrim
Fulgrim (Fireblade): hits 2.5 times, wounds 1.94 times and 0.810 after saves which IWND will take down to 0.477 at the start of next turn
Serras: hits 3 times, wounds 2.166666 times and 0.722 after saves which IWND will take down to 0.389 at the start of next turn
Unsurprisingly Fulgrim wins, but Serras puts up a real fight here thanks to her high Initiative negating Fulgrim's extra attacks. Unfortunately for her, Child of Terra saves his life by letting him edge her out in damage
Serras vs Mortarion
Serras: hits 3 times, wounds 2 times and 1 after saves which IWND will take down to 0.666 at the start of next turn
Mortarion: hits 1.667 times, wounds 1.111 times and 0.462 after saves which IWND will take down to 0.131 at the start of next turn
A crushing Victory for Serras as her negative to hit and saves combined with Mortarion's low attacks leaves him ineffectually flailing at her as she grinds him out in a delicious twist of irony. Of course, the battle will be over well before this happens at 11 rounds. No wonder he resents her, huh.
Serras vs Ferrus Manus
Serras: hits 3 times, wounds 2 times and 0.667 after saves which IWND will take down to 0.333 at the start of next turn
Ferrus: hits 1.333 times with Forgbreaker and 0.333 times with his Servo Arm, wounds 1.111 times and 0.278 respectively which after saves becomes a total of 0.579 wounds after saves which IWND will take down to 0.246 wounds at the start of next turn
Another ridiculously long fight but Serras once again edges out, since her saves are better and she can partially ignore Strikedown and concussive. With that said 18 rounds of combat makes this a slog that she should desperately avoid
Serras vs Konrad Curze
Serras: hits 3 times, wounds 2 times and 1 after saves which IWND will take down to 0.666 wounds at the start of next turn
Konrad: hits 3 times, wounds 2.25 times and 0.937 after saves which IWND will take down to 0.604 at the start of next turn
Konrad dies in a straight up fight but Hit-and-run + widowmakers will pretty handily turn the fight in his favour what with ignoring saves and all. It turns out Batman CAN beat anyone with prep time!
Serras vs Vulkan
Serras: hits 3 times, wounds 2 times and 0.667 after saves which (rerolled) IWND will take down to 0.001 wounds at the start of next turn
Vulkan: hits 1.333 times, wounds 1.111 times and 0.463 after saves which IWND will take down to 0.130 wounds at the start of next turn
Vulkan wins because Serras can't really hurt him (she likes him too much to really
try)
Serras vs Lorgar
Serras: hits 3 times, wounds 2 times and 0.667 after saves which IWND will take down to 0.333 wounds at the start of next turn
Lorgar: hits 1.667 times, wounds 1.389 times and 0.579 after saves which IWND will take down to 0.248 wounds at the start of the next turn
Lorgar's save is increased to 3++ against attacks from Force Weapons, allowing him to stay in the fight, but Serras' sheer volume of attacks will eventually overwhelm him
Serras vs Perturabo
Serras: hits 3 times, wounds 2 times and 0.667 after saves which IWND will take down to 0.333 wounds at the start of next turn
Serras (Blinded): hits 2 times, wounds 1.667 times and 0.556 after saves which IWND takes down 0.222 wounds at the start of next turn
Perturabo: hits 1.333 times with both, wounds 0.889 times with his hands and 1.111 times with Forgebreaker and 0.370 and 0.463 times after saves respectively, which becomes 0.040/0.130 wounds at the start of next turn
Perturabo (with Serras Blinded): hits 2 times, wounds 1.667 times and 0.695 times after saves which IWND turns into 0.362 wounds at the start of the next turn
Another victory for Serras comes when Perturabo doesn't have Forgebreaker. When he does this becomes a loss in the other direction as Serras won't kill him before she becomes blinded and then she becomes essentially unable to hurt Perturabo
Serras vs Alpharius
Serras: hits 3 times, wounds 2 times and 1 after saves which IWND will take down to 0.667 wounds at the start of the next turn
Alpharius: hits 1.944 times, wounds 1.512 times and 0.630 after saves which IWND will take down to 0.300 wounds at the start of next turn
As usual, Alpharius loses. Badly.
Serras vs Rogal Dorn
Serras: hits 3 times, wounds 2 times (Dorn cannot be wounded on more than 3+ thanks to his armour) and 0.667 after saves which IWND will take down to 0.333 wounds at the start of the next turn
Dorn: hits 2 times, wounds 1.5 times and 0.625 after saves which IWND will take down to 0.417 wounds at the start of the next turn
Serras loses thanks to Rogal's ̶G̶L̶O̶R̶I̶O̶U̶S̶ ̶M̶U̶S̶T̶A̶C̶H̶E̶ Auric armour, which cripples her ability to wound him combined with his own sky-high saves, allowing him the time he needs to chainsword her to death.
Serras vs Corvus Corax
Corax: hits 2.667 times (Scourge)/ 2 times (Shadow-walk), wounds 2 times (Scourge)/ 1.5 times (Shadow-walk) and 0.832 or 0.624 times respectively after saves which IWND will take down to 0.5/0.291 at the start of next turn
Serras: hits 3 times (Scourge)/ 2 times (Shadow-walk), wounds 2.5 times (Scourge)/ 1.667 times (Shadow-walk) and 1.667/1.111 times after saves which IWND will take down to 1.333/0.888 wounds at the start of next turn.
Once again Serras' extra attack and high saves win the day, though Corax can even the odds via hit-and-run, in which case odds are roughly even (duh.)
Serras VS Jaghatai Khan.
Jaghatai: hits 2.666 times, wounds 1.333 times, 0.555 wound after saves with IWND bringing this down to 0.222
Serras: hits 3 times, wounds 2.5 times, 0.888 times after sames with IWND bringing this down to 0.555
The Khan's oddly low Weapon Skill sounds his death knell as Serras drowns him under a flurry of attacks.
Serras vs Horus.
HAHAHAHA.
No.
Horus swats her aside in 5 rounds after debuffing her to hell.
Serras vs Leman Russ
NOPE. NOPE. NOPE. ALL ABOARD THE TRAIN TO NOPEVILLE.
Serras gets ̶y̶i̶f̶f̶e̶d̶ beaten by the ̶A̶r̶c̶h̶-̶F̶u̶r̶r̶y̶ EXECUTIONER OF THE EMPRAH as the negatives to hit and great saves she boasts about get turned against her with Mjalnar's
sever life making sure she can't escape.
Serras vs Magnus
Serras: hits 3 times, wounds 2 times and 1 after saves which IWND will take down to 0.667 wounds at the start of the next turn.
Magnus: hits 2.5 times, wounds 1.667 times and 0.695 after saves which IWND takes down to 0.362 wounds at the start of the next turn.
NERD FIGHT! Serras' extra attack and saves lend her the edge, though Magnus'
Psyfire Serpentia actually allows him to win BEFORE melee with S8 AP2 shots at any range thanks to
Eye of the Crimson King. Ironically, his best bet to beat his sister is pure, old fashioned Dakka since at ML5 she is perfectly capable of Denying all of his powers (which is even more likely thanks to SotSS letting her reroll every Deny test). Buffing himself up with biomancy is an option, but Serras can do that as well, with her greater initiative allowing her to eke out a win anyway. With that said, he is
fully capable of melting her if he takes the
Mind Wrath upgrade and rolls well on the
Pyromancy table, with up to 18(!) mortal wounds piled on a round.
Infernal Bargain is also a must since negating perils prevents Serras from using the
Sceptre of Hdaelyn to turn his sons (or him if he is
especially unlucky) into gibbering
CHAO..GDYGDSYUFKAYUFSADRELLL.
Really, these two are more or less perfect counters to each other if played properly, so battle between them go nowhere fast. Avoid this match-up at all costs if you want anything resembling a fun time.
Serras vs Roboute Guilliman
Serras : Hits 3 times, wounds 2 times and 1 after saves, 0.903 after the reroll from the
Armour of Reason which IWND will bring down to 0.570 wounds at the start of the next turn
Guilliman (Round 1): Hits 2.5 times, wounds 2.083 times (Hand of Dominion) and 0.868 after saves, which IWND takes down to 0.535 wounds at the start of the next turn
Guilliman (Round 2 and after) : Hits 3.333 times, wounds 2.778 times and 0.924 times after saves, which IWND takes down to 0.592 wounds at the start of the next turn.
Papa Smurf gets shat on if using the
Gladius Incandor, but the S10 hits of the
Hand of Dominion give him the damage output he needs to end Serras in turn 10, 1 turn before he dies (and if this fails, the concussive effect could kick in, reducing her initiative next round for a ~18% chance for him to kill her then too). The rerolls of the
Armour of Reason also help, lowering Serras' own damage
just enough for him to get that extra 1 turn which he needs for a victory. Finally,
Preternatural Strategy pulls its weight, giving him even MORE hits as the battle goes on.
As it turns out, Serras is much better off being Penetrated than she is being Fisted.
Serras vs Sanguinius
Serras: hits 3 times, wounds 2 times, 1 wound after saves (0.5 wounds if Sanguinius charges to reroll his invuln) and IWND will take that down to 0.667/ 0.167 wounds at the start of the next turn.
Sanguinius Round 1: hits 3.5 times (Blade), wounds 3.111 times, 1.296 wounds after saves and IWND will take that down to 0.993 wounds at the start of the next turn.
Sanguinius Round 1
(on the charge): hits 4 times, wounds 4.389 times (including HoW from the Spear), 1.832 wounds after saves and IWND will take that down to 1.499 wounds at the start of the next turn.
Sanguinius Round 2+: hits 3 times, wounds 2.667 times, 1.333 wounds after saves and IWND will take that down to 1 wound at the start of the next turn.
Just like Leman Russ and Horus, the Great Angel Wrecks Serras' Shit, all the while looking Fabulous. For extra Lolz he can Hit-and-Run for a charge bonus on every round, which Rerolls his invulns and increases his damage to the point where he can Shred his sister like a Blood Balloon
( IN 2 ROUNDS ). No wonder Horus was scared of this guy. Psychic powers can help Serras even the odds, but his
Great Wings ensure that he can hunt her down well before the Psychic Rape Train is loaded.
This guy is the worst match-up possible for Serras.
Don't. Even. Try.
TL;DR- Serras does surprisingly well!
But don't be fooled. That extra attack massively skews the results, adding a full 20% to her damage on average that wouldn't really play out in a game, so she'd likely lose a lot more than shown here (and her battles on average last 8 rounds or so, so no real victories either). With that said, her high initiative coupled with a ridiculous save means she can survive pretty well against anyone, making her a decent tarpit in a desperation scenario and excellent at lasting long enough to ̶
r̶u̶n̶ ̶t̶h̶e̶ ̶f̶u̶c̶k̶ ̶a̶w̶a̶y̶ tactically withdraw so she can safely cast.
