Rune Fencer sounds like a WoW Clone Death Knight to me.

The death knight uses a unique rune-based resource system to govern his/her spells and abilities. Three rune types exist: blood, frost, and unholy, each with an attached color and symbol. Using certain abilities exhausts one or more runes, starting a cooldown of 10 seconds. After the cooldown, the runes refresh. The death knight can use spells to turn a rune into a Death Rune, which can be used as a blood, frost, or unholy rune. In addition, whenever the death knight uses a rune ability against a foe, it builds up a certain amount of Runic Power. This Runic Power is only used by few abilities. All abilities that use Runic Power use a set amount, like Death Coil. Death knights cannot reallocate the number and type of runes - they are fixed to two runes of each type.
