Physical damage from Earth spells

[Ion Silverbolt]

Does anything boost the damage of physical damage in the Earth skills? I'm thinking that % adders would but does anything else help? Even strength?

I notice Int raises elemental damage. I was just wondering about the physical part. Might make volcanic orb still useful for a warrior with low Int since he won't have Int boosting fire damage.

I play the Juggernaut, earth/defense. Volcanic orb was great until epic. You simply cannot do a hybrid past normal. Balancing your gear and skill points just doesn't work.

The first improvement to Volcanic Orb makes it stun in a radius. I don't think that's useless regardless of your build or level. It's not a long stun but it's enough to thin the unstunned mobs in the area.

+% Damage items and skills should increase physical damage. Other than that, I think not o_O

i didnt yet see a skill where +% damage items work and the attribute doesnt, so im gonna go ahead and guess that str works too

"Brimstone:
