Blindness/Deafness seems to miss some script stuff

Reproduce:
Be wizard with Enchantment focus granting Blindness/Deafness for free
Cast Invisibility on self
Cast Blindness/Deafness on hostile mobs

Expected:
Blindness/Deafness causes enemies to enter combat, breaks invis

Result:
Enemies don't react, caster remains invisible

Sorry to anyone whose levelling I just made harder :<

A couple of enchantment spells work that way, actually. Including Blindness/Deafness, Charm Person/Monster, and Dominate Person/Monster. You can charm merchants for example to give a small bonus to you selling things. Dominate also works in that regard, and can be used to bypass some social checks that normally require a social skill to succeed.

If NPC' went hostile from a failed attempt, those would lose their value, as once you anger even one neutral NPC on the module, half the others who you have in no way wronged will also want you dead until next server reset, potentially meaning for IRL days.

Whether it is a bug or a feature, you can also dominate from invis, which is especially useful to a character who doesnt have summons but relies on dominates instead. Not particularly gamebreaking in my opinion.
