Greetings,
Well... Seeing as this competition has a point (the joke competition IS a joke itself), here be' my first entry.
Note: Black, please don't copy the format.
Advantageous Discharge
Recommended effect model: Lightning SphereEvent: The boss does a slow motion version of its spell cast animation (~3 seconds or so), after which it bursts out a lightning discharge, stunning and paralyzing every unit in the whole area (the boss itself, too) for 7 seconds.
Each second, the boss regains 4% of its total health, while all other units suffer from a 85% slowdown in attack speed, lasting for 14 seconds (including the time while stunned).
This is interruptable if a damage spell is casted on the boss while he's channeling it (the 3-second slow motion channeling).Triggered: Every 40 seconds.
