InEffect: Depends on what you are lacking. Generally, it's not too hard to just gather your party and continue. Maybe you'll have to replace an infantile chatterbox if you dragged her around, pretending she's a decent bard. In my experience, the biggest decision you are making at the house is how are you murdering the next room, not how to power through. The game just gives too much to the player and the house is nerfed to the ground. The only things you have to have is echolocation and FoM and neither is a problem.
In general, I'm leaving the murdering to Kalikke. I'm reasonably happy with my party and it follows somewhat your directives here (
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post139) with 1 DEX tank, 1 STR tank (your Val Bard build), 1 buff-bot (a Theurge), Jubi, Kalikke, and a greataxe paladin is my wild card, but I really do want to take advantage of the free mercs and try different stuff that I haven't tried throughout the game, so a few questions on your builds please:
1) Druid
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post664 You say " Overkill, but we needed the crane feats for the earlygame anyhow. " . If you created him at lvl 20, what would you pick instead of Monk & Crane feats?
2) Melee Sorc
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post41 Same question as above since "Crane feats you technically could live without altogether, but early/mid-game AC ramp is important too." . What to pick instead if you started at lvl 20?
3) Kineticist builds
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post140 vs
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post171 Would you pick any vs the other for a lvl 20 merc?
4) Slayer
https://www.gog.com/forum/pathfinder_kingmaker/ineffects_guide_v2/post334 I've read people raving about longbow Slayers. Could this be adapted from DW to ranged? If so, I take it Bard+DD are a waste?
Thanks in advance!
