In zone 3, I can't beat him! He just does a massive heal and then vera dies off. I get that I have to use subversion to make him do damage to himself, but he always does it in a differant place! Is there a average HP that he heals at?
When you get him down REALLY low, he casts a buff which makes him take in 200% more damage. Just stay alive until then. Like, put Roald onto Relentless or something.
subversion is one way to do it, but then theres a bit of luck involed. just make sure not to heal yourself until the mysterious affliction is gone, then switch to defensive for dux. after transforming, it's just a matter of outlasting him, because of his reduced defense.
The "Unknown Condition" switches damage and healing - it's basically subversion, and since it heals, it will damage you when you have it.
Here's a tip: all his moves require focus, so for Hydraulic, use Mind Freeze and Flash Freeze (they should be maxed), for Biological, use Disrupt, and for Psychological, use Traumatize every third turn (so he's stunned 2/3 of the turns and use Electrical Storm to recover focus).
When a player has Unknown Condition on them, just set all your teammates to relentless, and when they no longer have it, set Veradux to defensive.
