Magicka Pro Tip > Rock shield is beast

Rock Shield
You just got... *puts on glasses* ...rocked.

The Rock Shield is a self cast defense spell. It’s a great way to protect against enemy attacks and it really comes in handy when you’re surrounded by a mob. The stronger rock shields can be used so you can take the time to do something like an area of effect freeze spell followed by lightning or something destructive.

Earth = D
Shield = E

Rock Spell = DE then Mouse3
Stonger Rock Spell = DDE then Mouse3
Even Stronger Rock Spell = DDDE then Mouse3
Strongest Rock Spell = DDDDE  then Mouse3

EVRTing put up a good video on Youtube with a powerful spell combination which demonstrates how the Rock Shield can be used effectively.

I’d say a great place to use the Rock shield would be in the Challenge mode or the Bridge in Chapter 8 (The Minesweeper).

Definitely add this powerful spell to your repertoire.
