I have done 350 attacks for Smoulder and checked his hit chance vs Elite boss with 7 million power, then i have puted "hit rune" on him and did another 350 attacks.
- Without hit runes, chance to attack any target is 50%.
- With +110 Hit rune, chance to attack is 65%. So +110 hit rune, giving him some bonus chance to hit target. This Hit rune increased his battle potential by adding 30% more succesfull hits. Still, his miss chance is great and real difference can be seen only if you will make like i did - 300+ battles.
(This number probably will be higher vs players, because Hit will negate Dodge runes)

Morale: Hit is working for mages.
