Taken from my post yesterdy:
Emergency tactics: One spell only. Will look like a double cure (Two cure values instead of a combined value)
Short test of Dissipation: Cures went from 1900-2000 to 2.2-2.4k HP.
Could not click off the buff.
Does not affect healing magic potency stat itself.
Lustrate is unaffected.
Edit: http://prntscr.com/7jf6ml This is what base stats look like (MND+30 for that image).
Better OP/Title to come.
