Awakaener's Orb Gamba Machine.
Since the dt2 bosses already drop the torva kit that makes orbs useless. I suggest you implement a gambling machine and rolls 1 drop from any dt2 boss(Including the ones not ing yet, however using the only two available is also fine with the other two added later.) So rolls 1 random drop per 1 Awakener's Orb.(Except for orbs, no free rerolls.)
The rates of which items get rolled will be left for the team to decide, I feel like it should be on par or slightly worse than the drop rates from the bosses themselves.
