I never had much trouble w/ glavoid on bst.
I have NOT killed him solo. However, I have solo'd him down alot w/out much trouble.
Having the pet stay engaged while he absorbs is not usually a problem. I turn master around though.
I've used Yuly before, and last time I was using Broncha for the Killer Instinct and dispel (it absorbs your buffs).
You cannot have more than one pet melee'ing glavoid, or you will heal it more than hurt it.
Smn duo w/ bst Is a good lowman way to do it.
Glavoid is a fight I really wish I had a plague effect for on bst, like delta thrust from blu or shijin spiral from pup/mnk. LImiting the tp moves would be a big help. Maybe fargann w/ tp drainkiss would help in this way.
Anyway, I've never had trouble burning glavoid down to ~10% hp solo. But he tends to use alot more hp absorb and gets spammy at the end, which is when its hard to finish him off. I don't know if he woudl be less spammy solo or not.
There is a very good chance you can kill him, but I'm not sure. I didn't have trouble w/ the hate reset, but some of the AoE damage can stack up on you solo. (you can avoid the aoe spells easily enough from being far from pet when melee.. but you need to run close to snarl when hate is reset.)
