Thanks for playing. Could you describe the crash in more detail? I can't pinpoint when it happens in the video and I can beat the level during testing just fine.
The respec bug is a good catch, since that's a recent change I haven't had that much time to test everything. The issue with the old respec system is that it removed all commitment from the equation which is a cardinal sin of RPG design. With the new mechanic the player should get 8 per character over the course of the game which I think is fair. I also believe that having trade-offs is good too and it's another way to indirectly balance strong 3 cost perks like Sword of Michael or Supreme Fighting Spirit. Maybe I could award more respecs some way for people who really need them.
The pariah has low maximum health and their damage is largely determined by how much health they are missing. The trick to dealing with them is to burst them down in a single turn. They are also rogues so they are more likely to attack weakened party members and will actively try to score kills whenever possible. Their offensive skills costs half their MP so they can be bullied with MP drain skills or items such as mage leather.
The bulb they leave upon death turns into a fresh pariah in 3 seconds if not killed. The bulb has 10 health so it can be killed by a basic attack from anyone except Mosca who starts with 3 STR.
I really like these guys and I deploy them quite often. I hope you find this information useful and thank you for playing again.
