You have flat spell damage and spell percentage. Each spell deals flat damage, so lets use Teleport as an example. Say it deals 500 base damage. With a 300% increase from gear, it would deal a total of 1,500 damage: 500*300%=1,500
Certain items give you added base spell damage, so let's say an item added 500 extra flat damage: 1,000*300%=3,000
The same goes for main attack damage. This is why it's important to focus on upping your flat and percentage damage!
