So, my plan, because I think the plan should emphasize talking him down if possible, and that Knee-Groin Trick is the wrong tactic to use here. I am tempted by Alectai's idea of waiting for him to exhaust himself, but am much less sanguine about our abilities to tank or dodge a Finisher.
[X] Plan Talking And Knockouts
-[X] Stoke Virthing and Saemd (+374 Orthstirr)
-[X] Burn a Calm Charge and stoke Frami again (+187 Orthstirr)
-[X] Invest 4 Orthstirr in Silver Tongue (-4 Orthstirr)
-[X] All attack attempts are intended to be nonlethal, and we are going to try and talk him down even as we fight.
-[X] 60d6 Attack (60d6 tricks)
-[X] 26d6 Defense (26d6 tricks)
-[X] 0d6 Intercept
-[X] Activate Slipstream (-16 Orthstirr)
-[X] Use Goal-Tell to try and make our arguments to talk him down more persuasive (-3 Orthstirr), and add Fight of Our Life x2 to the Silver-Tongue roll (26d6 total if there's only one...we'll add one use each to two different rolls if there are several) to talk him down
--[X] Try speaking in English, perhaps his native tongue will help?
-[X] Make 45d6+5 (w/Hugareida) Honed x12 Lightning-Charged Flashfire Cleave w/ Puncture (-28 Orthstirr), and up to two 30d6+5 (w/Hugareida) Orthstirr Enhanced x15 Lightning-Charged Stunner Slam Firebomb-Strikes w/Puncture (-39 Orthstirr each) intended to render him unconscious without killing him (and avoiding any shaming strikes)
-[X] Against his first attack release our Fast-held 3Fold Inertia-Arresting Throw enhanced with Orthstirr for +36 dice for a 60d6+9 defense (-45 Orthstirr) that should also trap him temporarily, hopefully giving us more time to talk him down.
-[X] Against his high powered sword attack, if it gets through our existing defenses, use a Contested Movement adding one use of Fight Of Our Life for additional dice (-3 Orthstirr, 14d6+5) with the counterattack being a Lightning-Charged Stunner Slam Firebomb Strike with Puncture added on (-24 Orthstirr) again avoiding shaming strikes, and if that fails use Focus Guard (-14 Orthstirr) if possible
-[X] Against his actual Finale get out of the way using a combination of Ember-Wing Cloak and Backstep enhanced with 4 Odr (-15 Orthstirr, -4 Odr) and if that doesn't work use one of the Sway defenses mentioned below (we have a 6th that we are saving for this).
-[X] By default use Sword Guard and Atgeir Bodyguard to defend against everything else. In response to anything that gets through them try and use Halting Vortex (-4 Orthstirr), and if something gets through that use up to five 60d6+9 Reinforcedx59 Sway defenses (-61 Orthstirr).
-[X] Tactics – So, the plan here is to continue using our very high Sword Guard and Atgeir Bodyguard to defend as much as possible, but with a lot of alternate defensive options layered on, and try and talk Gabriel down while beating him unconscious if he doesn't listen.
I will also say that I think Skippy's plan should also at least stoke Saemd, and maybe use a Calm Charge like this plan does. We need all the Orthstirr we can reasonably get this round, I think.
EDIT: Added Fight of Our Life x2 to the Silver-Tongue rolls.
