PoE 3.21:Previously, modifiers providing a “chance to avoid Interruption from Stuns” worked in an unintuitive and inconsistent way. These cancel out a stun entirely, preventing effects that happen when Stunned. However, due to an oversight, they did not do this if you blocked a hit that would stun you. This led to things like Cast when Stunned behaving inconsistently depending on whether you block a hit or not.
These modifiers will now also prevent stun-specific effects from blocked hits as well, and will be described as “chance to Ignore Stuns” to more clearly communicate their actual behaviour.
