spiked turban reflex save stacking
The "starter" Spiked Turban granted by using Stone of Experience incorrectly stacks with Greater Stability. This behavior was observed on live servers just before U15.
(This might apply to non-starter version and also possibly other resistance items, but I have not tested)
Bug as seen in the in-game log:
spiked turban provides the following bonuses:
+3 enhancement bonus to fortitude saves
+3 enhancement bonus to will saves
+3 resistance bonus to reflex saves
As once leaked by a dev, most items that claim to provide a "resistance" bonus to saves in their description are internally coded to grant "enhancement" bonus. This is not the case for Spiked Turban's reflex save bonus. As a result, you can get a +3 stacking bonus to reflex saves from spiked turban.
1. Undress your character.
2. Wear a Greater Stability armor. Note the reflex save.
3. Wear Spiked Turban. Note that reflex save is increased by 3.
4. Optionally, look at the in-game log for information about stacking.
As I haven't tested other Resistance items, I am not filling a bug report, because I am not sure if it's a bug of Spiked Turban or Resistance items in general.
