Hey Guys, I've seen allot of different monks using lots of different runes for exploding palm. I wanted to explain why we see so many different runes being used. Its one of the very few skills in this game that almost all runes can be valuable in the right situation.
Strong Spirit: Use as a utility skill to maintain spirit if you don't have the crudest boots or value alternative passives more than spirit regeneration.
Essence Burn: Over all a poor performing rune now that Gundo is available. A very cool skill but even with Fire % its still way to low dps.
Shocking Grasp: Scales with lightning % which you are most likely using. Its great when you are speed farming... dropping EP once instead of 2-3 times.
Impending Doom: Very high damage output even without cold %, definitely an ideal choice for maximising your damage in higher greater rifts.
The Flesh Is Weak: Not great solo but v good for group fights agains Rift Guardians and large health pool elites. At the least you will kill the RG 20% faster its worth noting this skill is a separate multiplier so its more than this.
What runes are you guys using?
