Since I just dropped improved sunder temporarily, I can't test this myself.
Improved Sunder feat had several components:
-3 fortitude save (always landed, even on failure)
-10% fortification (when successful)
-5 AC (when successful)
However, the feat description and debuff in examine has been changed. The fortification is no longer included. The AC debuff and fortitude save debuff are intact for sure.
Can anyone verify whether the -10% fortification is still working? Thanks.
This nerf would be a major change for many of the people who took this feat as a raid boss debuffer. It would take this from nearly mandatory for heavy melees to a niche quivering palm helper feat.
