An idea to fix, in my opinion, the most broken and weakest tree in the game.
Flaw 1 : Henshin suffers from not being able to utilize spell focus and evocation DC's for their ki abilities, leading to weak damage, if ki abilities even hit at all.
Solution 1 : Arcane Archer can now utilize enchantment focus items and feats for some of their abilities. I figure it wouldn't be difficult for henshin to gain the same with evocation and enchantment DC's. They cannot pick spell focus feats unless they multiclass, but I've given them up to +3 to evocation/enchantment DC's in the cores. According to my basic calculations, a henshin under this new build could reach a stable and respectable 70ish DC for their abilities with a little effort, possibly more if the push for it. This is roughly the equivalent of your standard sorcerer's evocation or conjuration DC's.
Flaw 2 : Henshin suffers from what I like to call 'paladin syndrome', meaning they require too many stats to be effective and juggling them often means too much sacrifice for little gain. This leads to dumping strength and having only average damage and worthless ki abilities or dumping wisdom and having low damage and weak ki abilities. It's a no-win situation.
Solution 2 : Added wisdom to hit and damage in the cores. This provides them with the high wisdom required for good ki dc's and allows them to focus more on wisdom and less on strength. This also provides multiclass options with clerics, favored souls, and druids.
Flaw 3 : Henshin's unique abilities look interesting on paper, but in testing they're actually quite weak due to low DC's and lack of focus. They also cannot utilize metamagics or spell focus feats.
Solution 3 : I've boosted the fire and force damage in the tree to scale better with spellpower. Also, a couple abilities have been completely changed.
