Running
Running is an ego found only on boots and the lightning scales artifact which reduces your movement delay by 1 (to a minimum of 6). This stacks with other speed enhancers, such as the Swiftness and Haste spells, and has the advantage of requiring no maintenance to keep active. Bear in mind that suddenly moving faster may drastically change your combat tactics. Chasing down fleeing enemies and escaping pursuers will suddenly be much easier, but be aware that ranged units will abandon melee and switch to ranged attacks if you open some intervening space. Characters with permanent allies should learn Recall or change their travel speed with the CTRL-E command, because most of them will be left behind while exploring.
History
Prior to 0.13, this ego reduced movement delay by two auts. 0.13 also added the option to match your movement speed to that of your slowest ally.
