What's the point in qusting for this ? Latent effect ability's suck so much ***, hows a free summon supposd to bail u out if your at yellow hp anyway ?
Well, some smn go as /sch nowadays, which allows them to readily be able to drop their HP into the yellow by means of Sublimation. For some of the bigger hnm fights where the smn is calling avatars out from a safe distance, they'll be able to stay in the yellow without any real worry to themselves.
The Avatar Belt and the Nightmare Gloves are worthless for a Smn though, as the belt works only with /smn and the Nightmare Gloves only work when the Smn is asleep.
