Used this in Promyvion-Mea BCNM at 30% life. The NM had already gotten off two specials before I used it. Looking at the log, after I used this, the NM readied six specials, but never used them.
Well worth the time spent farming it, in my opinion.
It may have been a bug, or maybe you have to use it at a certain time, but I used this on Prom-Mea (at about 30% life left) and there was not any noticeable effect. The mega-boss kept using specials, kept attacking and doing things as normal.
Prevents the Promyvion bosses from using their TP attacks. During is about 20-30 second. Useful during the spam session that begins at about 1/3 life left.
You use it like you would a potion, but no target is required. It only activates when you inside the BCNM so don't worry about wasting it while testing a macro.
It can be used outside of the BCNM... I've "wasted" duplicate anima on Weepers before! ^^
(And before you all jump on me about duplicates) You can carry one, and Harith will hold the 2nd one. Until you either USE the anima, or DROP it, you cannot get Harith to make another anima.
