Spell Damage (soul Signal, Millenium, Etc.)

I've seen that soul signals with very high spell damage sell for a lot, and I managed to get a +305 one. However I'm not level 92 yet, so I was wondering if the +305 spell damage really makes a big difference or not. Does it get multiplied or something? I'd like to know how it works :P

 

Nope, it just adds on to the neutral damage of any of your spells.

Say if you deal 500 neutral damage, and with +600 spell damage you would get 1100 neutral damage.

 

Ah alright, thanks for telling me!
