@Akamatzu It doesn't heal it. When it's cursed, it's HP lowers by a percent, so if the mob is at 95% when it gets cursed, it appears that it jumps back up to 100%, even though it actually has less HP now.
This disc is probably more usefull for BLU and DNC.
It is the faster (and higher DPS) returning range for them both.
NIN and THF on the contrary already have the nice UngurBoomerang.
Ungur gives them Eva+8 (and HP+8) (For info that's a 100% drop and an even easier NM now we broke level 75 cap.)
I don’t like Jinx as a pulling tool, because you control less what will happen.
Sometimes the mob run behind you at his usual pace, sometimes not.
And then it can break the flaw waiting for it to reach camp, or even augment chance of link
(like when you pull a magic user or a ranger type.)
Effect don’t last long enough on solo debuff use.
A 100% proc. would entirely change things.
In conclusion better use (if not only) to my eyes, is for BLU or DNC puller with a little bonus during an alliance large slaying party in Abyssea when mobs live less than 30s.
