Good call o.O I guess you Could let your teammates do the damage... if you have some spare time on your hands, or just to say you did it (or just to say you didn't do it might be more accurate)
Urgh. I got mine by letting teammates do all of my damage for me and just stood there casting Free Will. If you can speed it up with indirect damage, more power to you.
Periodic damage doesn't count as damage for Pacifist? Have you actually tested this or are you just theorizing? No offense. I just want you to be wrong so that I didn't waste 45 minutes on a battle that should've taken 3.
Yes. Get high vitality and use Safe Guard, Ice Wall and Mind Freeze. Maintain Safeguard on at least Dux and chain Mind Freezes on the the Hydra (the middle claw). Dead Man's Plea is also useful.
I did it as a hydraulic. Trey you can't attack them much if at all... let your teammates do it, you just protect and heal. I haven't tried it as a Bio. Bios have a better healing spell than hydros, but hydros have ice wall, but bios have crystallize. Maybe bio would be easier for that.
I'm currently using Bio. I got so frustrated with this achievement, I even made a separate account and modded my stats and abilities. I do no more than 2000 damage in any one hit throughout the entire battle. This includes poison hits. My poison damage did approximately 800-1200 per hit. The side-hydras were easy to finish off, but the main Hydra was troublesome. I got into a habit of using a Toxicant Form, Break, Mutant Glands, and then it would stun me for four rounds, then I would repeat the process until it was dead.
After the battle, I did NOT receive the achievement, though not a single one of my damage counters exceeded 2000. Anybody care to explain why?
P.S. I'm pretty frustrated right now. Can't go back and do it because I had auto-save on. Fu.
The way to get this achievement, is, if you are using hydraulic, keeps using regulate on the hydra, as the hydra can't do anything without focus. You can also cast mind freeze, up to twice, depending on damage, so that gives you 6 turns of him not being able to do any damage, even if he has focus. Use this time to regulate him out of focus, and let your teammates slowly kill.
