You will need for this:
*A trial/alter/friend account of DF, weared in extravagant robes(purple) and 2 arcane rings, the alt will be resting all night.
*Your account and a macro which let u to use mana missile every night and it change your staff when it was broken.
*Tons of staffs xD and is good than u wear a mana efficiency bone helmet.
You will use mana missile on your alt, but not directly, u should hit the floor near your alter, beacuse since the last patch splash magics are nerfed and u will hit your alt for 2-3 hp dmg each 3 seconds, this is a great amount of mana missile and u can gain 1-2 points of intelligence each 8 hours, but u never will kill your alter
Extravagant robes cant be broken and arcane rings too, because its bugged in game.

Staff in row 1 of your hotbar, mana missile in row2 of your hotbar and you need to use u as unsheate object key in your input bindings in game.
