So today i got an UV'd brandish with DMG bonus vs gremlins of V.High and vs slime of medium.
So my question is, should i wait for the shroud of Apcrea or make it an Acheron?
PS. i alredy have a silent nightblade with no UV's, i'm wondering which one i should make which.
Do you want to kill things quicker or poison things?
It also depends on your play style, do you want to charge your sword or just go around triple swinging it?
And also if you have a maskeraith then you definitely don't need the obsidian edge.
IMHO I think you should go for acheron because of its raw power, the only place where obsidian edge is able to hold its own is in arenas with menders (if you lack a maskeraith) but even so, if you like to go straight to chopping up menders with a sword, then the acheron will come out on the top.
But if you want to get an obsidian weapon that outclasses its normal relatives, the other two weapons are viable options.
But anyways, as you get damage boosting armors, the UV's will be irrelevant.
