Issue:

If you have double specialized thief, that gained permanent +1 luck bonus, you will not be able to benefit from Luck spell at all.

Note that I am using only Ice Knife + all Luck endgine fixes in my playthrough (using custom made EngineFixes.tph). No other fixes included (don't like some balance changes disguised as "fixes").

Additional thing worth mentioning, is that in valilla game +1 luck bonus from thief specialization does not work at all (which is fixed by endgine Luck fixes, as long as specialization is gained after fix is applied).

P.S.

Best way to check current luck bonus is to look at attack roll. If target has no damage type modifiers to AC, bonus displayed will show exact luck bonus your character has.
