OK, so, Liang He has a few unknown we have to watch out for 'just in case'. This is amusing a fight, and not some more tricky challenge.
Liang He said:
Seventeen years old. First third realm cultivator from a soldiers family in emerald seas. Primarily a swordsman. Humble and dutiful in most respects, he is known for taking a great deal of pride in his dueling ability.
Cultivation Green2/Bronze2
Qi: B15
Initiative: B5
Phys Hit: B35
Phys. Avoid: B25 Phys. Armor C2
Sp Avoid: B10 Sp. Armor: C12
Primary Elements: Wind, Fire, Heaven
Spirit Beast: Azure Inferno Falcon
Green1/Bronze 1
Primary Elements: Wind, Fire
Bolded is where he is better than us in a contest (Phys Hit bold, in this instance, is compared to our Phys Avoid), Italics are where we are better.
The biggest unknowns are about our opponents attacks. So I'll first talk about how to deal with his offence.
Here are the possible variables:
- His spirit beast. We know nothing about its offensive stats or capabilities beside it being flying Fire/Wind.
- His domain weapon. While ours is of higher quality, it really doesn't matter if his is 'only' made from Green 6 material at this point.
- We don't know his Phys Pen stat.
As an aside that I'll go into more later, we don't have to fear from combos between the spirit beast and Liang He, nor do we have to fear ramp ups, just specific discrete attacks.
For his spirit beast, there is nothing much we can be sure of when it comes to its offensive abilities, though as a Falcon, it
probably has pretty decent perception, and maybe even exceptional one, so going stealth is probably not the way to go. However, it's worth noting that Echoes and HRA should be just as potent against the Falcon as against Liang He.
When it comes to his domain weapon, we can make rough guesses. He likes dueling, so he probably has a domain weapon vs domain weapon one, and it's likely a sword. Moreoever, we can make appropriate guesses as to his Stat + Skill combo being Dex + Sword:
Initiative: B5
Phys Hit: B35
Phys. Avoid: B25 Phys. Armor C2
His Phys armor being so low tell us he has at best average stamina, and his P.avoid being similar-ish to his P.hit indicate that he has likely good Dex and uses it for hit. There is two scenarios here: Either he has Dex B, Sword B, 35 in passive/gear bonus as well as Dodge B and 25 in passive/gear bonus; or he he has Dex A Sword B 15 in bonus (and Dodge B with 5 in bonus).
If it's the former, our Domain Weapon should be quite a bit superior to his. If it's the latter, and his is more specialised toward dueling, we can expect his to be a bit superior to ours, depending on elemental coherency he has. Assuming he has the same rank domain as we do, but I think we can assume his domain rank is at best equal, considering you'd basically be well on your way to Green 4 before most get the next domain rank. If it's worse than ours, his domain weapon just can't compare.
I'd say that whether his domain weapon is a bit superior to ours or significantly inferior doesn't matter that much though, because ours should be good enough to at least counter his for a significant period of time.
His Phys Pen stat is the most likely to matter. Now, it's possible he has a significantly better Physical Penetration derived attribute than expected. Ji Rong certainly did, with a surprise 'My STR is super high, Psych' factor. There is 3 scenarios here: his Pen is A, it's B, it's under B. The third scenario doesn't need to be examined with much more than "If it's the case, we can ignore his offence completely".
Basically, we are having a huge advantage here defensive wise because while his Pen would be equal to our Armour (as such something like half damage would be done I think?), he can't ramp up his offence but we can ramp up our defence armour wise. I am of course talking about the glory of making our opponents drunk:
Phantasmal Revel's Regrets: C
Releasing a pulse of chaotic qi into the environment at Close range to Ling Qi, Sixiang disrupts the flows and constructs of their foes. Soaking their meridians in qi designed to emulate the fogging effects of heavy inebriation, she causes their control to of their techniques to slip. Attempts to dispel a single effect on up to five enemies within range.
Sixiang's offensive dispel is Presence B + PRR C= C15 + Passive 10 = C25, and can work on up to 5 enemies at once. Given that the Falcon is a fire/wind bird it likely won't have resolve B, and given that Liang He has s.armor C12 he likely won't have Resolve B either. This means that not only can Sixiang spam PRR, but she can dispel B rank buffs from both Liang He and his spirit beast with some reliability.
So yeah, I'd say that Sixiang will likely do more in the fight than the Azure Inferno Falcon. They'll completely cut off their ability to ramp up. As such, we can consider Liang He's stats his 'in battle' stats, rather than 'before using buffs/techs' ones, like for Ling Qi.
If he has Pen B? That's going to be effectively Pen C thanks to Echoes against Armour halfway toward A as well as bladed weapon damage reduction from HRA
and Fire damage reduction from Zhengui. We can expect Ping damage once we have Echo up, especially so once we have HRA up, though him having initiative is mean.
That scenario is much riskier. Basically, in this one he'd still do significant damage even after Echoes and HRA if his techs are potent enough, and so in this scenario the value of being in darkness (FVM provide darkness at FVM8) and increasing our dodge as high as possible (GCD scales with light levels) might be wise, though "take him down as fast as possible" might also work. I'd note that while our pre-buff P.Avoid is lesser than his P.Hit, GCD is a pretty potent dodge buff and he can't actually ramp up his hit that high thanks to Sixiang. Perception filters might also work.
I'll also note that Deepwood Vitality might be of use if he tries to nuke us.
tl;dr While there is multiple points of unknown when it comes to his offence, the only real variable is going to be if his Pen is A, and even then a combination of increasing our dodge, deepwood vitality, perception filters and our own offence vastly outstripping his defence means that should be at most annoying because dammit he has initiative.
Oh, right: Our offence? it should vastly outstrip his defence without a contest, though if we do decide to do the Traveler's End nuke we might want to add Echoes for increase our pen a bit for full damage first.
