Did they finally work around Snipe?

Yes, it did used to work, and I have yet to check, but I believe it still does on many of the earlier ones (excluding blood stirges). As another example, those ghosts in Heny that you needed to explode to kill, and the Bot-Catcher pre-defense downed could be OKOed by snipe.

The thing I was trying to get at was if they were actually starting to work around it. As for the boxes, I believe you had it at "set damage flag". But I'm going to assume that the JQ Hoguls have boss flags and really high hp unless someone else can find some sort of evidence.

It seems to me though, that the problem lies within this "invincible flag" you mentioned. We go through those like nothing and I'd like to see it changed.

The bot-catcher mobs just have insane avoid and a variant of the ban skill (Dodo and a PB hawk statue has this too). There's nothing that make them special otherwise. The Henesys Ghosts just have insane avoid.

Mind if I ask what made you think the JQ Hoguls have the boss flag?

Also, what makes a monster "invincible" should be handled by the executable and server code. Nothing much we can do if that doesn't work properly.
