Elemental vs Specific Damage

[Eatmoremeat]

I'm trying to build a lightening based build and I was wondering if its ok to use items that have Elemental Damage % increase instead of specifically lightening % increase.

Both is fine, just check the suffixes percentage or flat number range, is it worth it?

both are fine but lightning stat can roll higher then elemental stat

Thanks for the responses everyone, I was just worried that maybe there might be a situation where elemental damage might not stack the same way as just lightening damage. I'll try to get lightening damage to get it to roll higher but I have a few good items that have elemental instead of lightening now, so I should be good till I find something with higher lightening stats.

Lightning damage should be able to roll higher than elemental but otherwise it should be the same effect. Just elemental would also buff cold / fire spells if you used them.

I find that for a caster %spell damage is better (seems to roll higher) other stats like crit chance, crit multi and cast speed may also be better raw damage multipliers than elemental or lightning damage as well.
