Sprint

Description "Sprint"
This skill allowed for a momentary, lightning-fast sprint, and was a skill that consumed a large amount of stamina, but to the undead which possessed the race characteristic of 'never tiring', it was a great skill he'd be able to use again immediately after the skill delay.

Amongst those skills, Sprint was especially amazing. It had a huge effect in increasing his speed regarding his travel, evasion, and of course his attacks as well, but when it rose to the low rank stage, it became much easier to put that speed into his attacks. With just that, it felt like his fighting ability had increased by 30%.

In exchange for the skill duration shortening, when it is used in tandem with a attack skill, the attack is amplified.

Combat Sprint. It didn't simply enable one to move fast, it would increase the body's reaction speed, albeit for a short time.
