It appears that Inspirations (combat-related) are a lot weaker than either the text descriptions provided or the Devs thought they were:
DEF (Luck)
S – 12.5%
M – 25%
L – 33%
ACC (Insight)
S – 7.5%
M – 18.75%
L – 37.5%
RES
S – 10%
M – 15%
L – 20%
DMG
S -25%
M – 33%
L – 50%
The Resist and Damage inspirations are working as advertised, but Defense and Accuracy are, clearly, not.
Castle has added it to the bug list.
Cue endless discussion of whether this was always a problem (“The Devs are incompetent dolts!”) or was a stealth nerf (“The Devs are evil manipulators!”), which sound oddly like discussions of Washington politics …
