Dwarven Runes

Dwarves can use ylem stones to make small dwarven runes, with dwarven runic words etched into the stone. Unlike a traditional rune stone, these are much smaller and have very little real power. Instead they will have instant effects that are 20% as strong as the actual spell put into the stone. For example, you could make a dwarven healing rune that when placed on the head of the target would heal the target for 20% of what Essence Bolt would. Or perhaps a dwarven fire rune that when thrown at the target would do 20% of what firestreak would do. The upside here is that you can make 10 dwarven runes from one ylem, instead of just 1 rune stone, and these stones could be fashioned into things like arrow heads, or simply thrown or used quickly. Dwarven runes cannot be recharged however, and their use is 20% of that of a traditional rune stone.
