Soul Charge

I don't understand how does it work.

When using it, it just adds some Magic Attack, and in the stats window it doesn't increase the weapon attack range at all. So, how is magic attack of any use for warriors? How does it work specifically? I heard it actually gives holy elemental bonus even if Isaac's thread says that it doesn't.. is it true?

Thanks in advance.

Yes, it's been proven by a couple of people who played KMS that Soul Charge does indeed give a holy elemental bonus.

And I believe the giving extra attack works the same way as Berserk.

Partial Holy Element, fixed % increase to damage. No idea why it adds magic attack, but it was a copy paste from Pallys.
