Well, I was wrong, Heal Strat still is fine. Just needed to swap out the Cursed Coronet for anything else. Power Buster on Gisarmory to keep damage down. Set up some Catalysts for the final damage, Super Power Booster and Overcharge plus 50 Star Burst, if I didn't hit the Block, I might've one-hit. Maybe.
Not sure if there's issues if I manage to kill Gisarmory without hitting any of the dialogue triggers, or manage to go from above 1/3 damage dealt, to below 2/3 in one hit.
....
Dialogue advice for the return to Defia:
"But the command scrolls for the rampaging golems were forged in both Klenze AND Holvan's handwriting"
Might be better as "both of your handwriting" or something, since she's speaking to them both already? But there's golems and that woman in the back, that she's addressing as well, I guess.
...
Good thing I checked the Golem Eye description. I thought it was just an eyeball. Yeegh.

Should the Orange enemy outside Tathaln's Cabin, respawn?
