Notorious for having suffered a record number of self-inflicted concussions, most of which resulted from running into street lamps and wandering adventurers.
That's just Goblin Dice, the special TP move that all Goblin NMs in Dynamis-Jeuno have. The result of the attack is one of the following AoE effects at random:
1.) Ability Recover (your job ability timers, including 2-hours, are reset to 0; this is a good effect, but it's very rare) 2.) magic damage that strips shadows. 3.) damage that strips 2-3 shadows. 4.) Poison 5.) Disease 6.) Slow/Silence 7.) TP Reset 8.) HP Max (restores your HP to full, also good but rare) 9.) Sleep 10.) Dispel
As a WHM, I've found that the most annoying one is the Dispel... it tends to take off my Reraise III effect. x.x
