There's a vendor right nearby so you won't have weight issues really. Tusks are decent plat and you'll have EF pretty much all to yourself other than the occasional wizzy killing giants. Plenty of open space for instill doubt too. GL.
*Also just a side-note: late teens to early 20's monks wanting to solo should try DE guards in Nek forest. Yeah the guards at the bridge take a while to respawn but you can fill the gaps in with stone/iron guardians which traipse around near the Lavastorm zoneline along with the standalone guard there. Bronze swords off the lower level guards and regular long swords off the higher ups will compensate for the lackluster loot off the guardians. Added to that, you can work on split pulling while at the bridge. That said, try not to ragequit when fd fails and the dragoon ganks you. Just remember, the newb inkies were standing by cheering you on, not him.
