SURGE is a toggle command which, when turned ON, increases the damage you can do with combat spells. You may also set the power level (1 - 5) at which you wish to surge (i.e. the size of the damage modifier). However, this added energy comes at a price - the mana required to cast your combat spells will increase in proportion to the power level at which you set surge. The maximum surge power level is attainable by sorcerers, wizards and mages. Other classes have a lower limit.
Prerequisite(s): Magic Lore.
Syntax: surge on.
Syntax: surge off.
Syntax: surge <power:1-5>.
Note that all races and classes have the same chance at surge failure or success.
