Not sure where this belongs as it's WoW related.
Examples
Power Word: Shield
If used between levels 1-89, makes you immune to all damage for 20 seconds. Breaks when there are 2 seconds left on the buff and when four or more players try to burst you down.
Fear
Makes your target run around in fear for 8 seconds, does not break no matter how much damage they suffer.
Avenging Wrath
Gives enemy mages 20% more damage for 30 seconds.
Dragon Roar
Deal damage while causing an insignificant stun that might as well not exist. Also, get sued by Bethesda.
Repentance
You chose a talent that nobody ever uses, grants the "Idiot" debuff. Is not removed until the talent is changed.
What do you think other spell tooltips would say if they are honest? :3
