Nope, they stack. When you have both, each crit triggers 2 attacks of opportunity from nearby party members.

Thank you. Then it shouldn't be a waste -- as long as I can put it on another ally too. Also read somewhere that Seize the Moment is supposed to work from ranged attacks, though I don't know if that is correct or not. In theory we could then stick it on Ekun, and if he crits and a melee fighter is nearby who also has it, he should be able to get AoO from the crit. If it works that way, though...? Who the hell knows :D

Plus, anything Ekun crits is likely to be very dead very fast.

Well yeah. That's the reason you don't drag crisis for too long.

Regarding that... Regongar with 4 levels into Dragon Disciple with a +str belt is a great help there. Just dont forget to bring military to high level before that sh*t begins.

Sure, and it's possible I dragged it a little too long. But I wanted to. Because earlier I did the chapter too quickly, apparently, which meant that some things that happened in my first playthrough didn't, like the wizard getting attacked by trolls. Plus, the chapter specific problems evaporate once the chapter has been solved, so that is kinda nice. At least that one did.

Looks like some quests that have high DCs will auto-succeed as well, if it's a unique problem for example. So putting those +5 coins into them is a waste (but I still keep doing it, haha). For example, the Grey Rebellion had a DC of 25 in my game. I got a combined roll of 24, but it succeeded. Looks like we merely need to put somebody on it, and it will be fine. Same with those 1-day Bald Hilltop events, at least from what I can tell.
