Yes, you can farm Deleras, Threnal and Sorrowdusk and get a metal-based staff as a rare chain end reward. However, with the new weapons with the 2[xdx], I've yet to see any of these new quarterstaves drop with metal-based properties.
The Devs went out of their way to make sure that handwraps got included with the metal-based properties with these new weapons, yet staves were left out once again. I even brought up that staves suffered the same problem that handwraps suffered in Closed Beta when people were crying about monks being left behind....apparently to no avail.
So to have a DR breaking quarterstaff, players must either farm Epic Nat Gann (but only for Dex based characters and only Devil DR after slotting), craft a regular quarterstaff or play the random loot game of finding a 2[xdx] Metalline of Good/Righteous quarterstaff.
Will players see any progress with melee quarterstaves (aka Acrobat's favored weapon)? The quarterstaff was left of the group of weapons for the Calomel weapons, so the Acrobat melee style is currently the only melee style without a dragon beater. Outside of buying from the DDOStore a Blessed weapon (which are now subpar with the 2[xdx] weapons) and farming for a random and rare end chain reward, there's no real way for players to get metal-based staves. On top of this, the named staves are split between STR and DEX based and the Devs haven't confirmed one way or the other if Acrobats will be able to use Dex for all quarterstaves when the enhancements are changed.
Things might be messed up for handwraps, which we hear alot of complaining about, but things are just as bad (or in some cases) worse for quarterstaves.
