Clearing gds is a combination of target priority, room layout, and what monsters are in the gd, so the only way to learn how to clear them effectively is by doing a ton of gds.
This is odd, I'm doing that and its making me speak in my clan chat, not the DGS one, and adding a / before what I type, lol You are probably on your clan tab so you only see your clan's chat. The way they updated that tab made it so anything you type outside of pm's in that tab goes to your chat.
Gorg plate until you find a hood. EDIT: a prom 2h is much more versatile, a primal rapier only has a niche use on certain creatures that are weak to stab such as brutes or dogs.
