This trick requires a Staff Of Mana. The sorcerer begins
with one. Set the Mana recharge ability to a quick key, such as
[F5], and any other ability nearby (Firebolt, Healing,
etc.). Set Mana charge ([F5]) and right click to replenish
your Mana. Immediately after you right-click, change your ready
ability to another ([F6], [F7], or [F8]).
If done correctly, the charge of your staff will not have been
spent. This trick will make the game easier for the sorcerer,
since you will not have to buy dozens of Full Mana Potions, saving
money and space for healing potions on the belt and found equipment
in your inventory.
