Healer here, not liking GNBs Invun

[JunseiKei]

I've been leveling GNB lately. Honestly, Superbolide is a better Living Dead - you don't need to heal their maximum amount of HP and they are invulnerable. I try to pair it with Aurora (GNB heal). If I could change anything about Superbolide, it'd be to add a convalescence effect to it or increases the potency of Brutal Shell's heal and shield. A regen or something on them will go a long way; again, it's not Living Dead, so you just need to get them up a little bit and the invulnerability sees to the fact that you will be gaining more HP on them.

Speaking from a healing main perspective, too. If you're an AST and already used Essential Dignity, don't forget Synastry allows you to double dip on healing effects if you put it on the tank and proceed to heal that same tank (seriously, Synastry laughs at Living Dead).
