New Wizard Spell / Feature - Talking Hat

[Cicadalek]

I'm not sure what a "fair cost" would be, given that it uses up one of your 4 spell points. Going from 1 to 2 cost would be a huge change - is the hat really worth more than two of the any other spells put together?

If it is too powerful then some of the abilities could be removed or tweaked. Maybe the acid spitting thing could be on a cooldown, so if you have enough acid on hand then the wizard is forced to back off until i can be resummoned.
