Assume a level 9 warlock has following damage dice:
-5d6 from base EB
-2d6 from Mortalbane (Feat, does not require CL)
-2d6 from Greater Chasuble of Fell Power (Item – Caster level 9th)
-2d6 from gloves of eldritch admixture (Item – Caster Level: 3rd)
Maximize spell like ability feat mentions:
The spell-like ability you wish to maximize can be chosen only from those abilities that duplicate a spell of a level less than or equal to 1/2 your caster level (round down), minus 2.
If this warlock wanted to maximize their attack using all of the dice above, would he have to re-calculate the Maximize Spell Level according to formula [(CL/2) – 2]? If that is the case, would you take the item that requires the highest CL or add up all the spells that requires CL (1 for EB + 9 for Chasuble + 3 for the gloves)
