You are referencing the stun related to BASH which does not have a duration, just interrupts.


This is stun related to spell effects, which does indeed use the effect duration.

				//Block the stun part and not the whole spell, we do it here, also do the message here so we wont get the message on a resist

				//max_level of 0 means we assume a default of 55.
				if (max_level == 0)
