If you've got the aforementioned key combos stuck in your muscle memory you are a true mage, a man who bends the warp and weft of reality to your will, capable of destroying not just everything in your path but yourself and all your friends too.
Magicka is a superficially simple game with a great deal of depth. You play a wizard with access to eight elements, each one activated by pressing a key:
Q - water
W - life
E - defense
R - cold
A - lightning
S - arcane
D - earth
F - fire
You have 5 rune slots. Tap a key to fill a slot. Right click to cast, shift-rightclick to area cast, middle mouse to cast on yourself. As you combine elements, you get effects. Fire alone is a flamethrower spray. Arcane alone is a beam of energy. Combine fire and arcane and get a beam of fire. Water makes things wet; lightning does extra damage to wet; combine fire and water you get steam; combine fire, water, and lightning and you get electrified steam; combine that with arcane and you get a beam of electrified steam.
Fire said beam into another wizard's beam and they'll join into a Death Star laser.
Laugh. LAUGH as you shower in the exploding giblets of your pitiless foes. CRY as you accidentally set yourself on fire, or richochet a spray of frost needles off your buddy's shield and gib yourself.
Is that not enough depth? You want MORE DEPTH?
Certain rune pairs can combine into new runes! I already mentioned steam! You can make ICE! You can make well okay that's all I remember
Wait, you want MORE DEPTH?
Well certain combinations of runes are MAGICKS. Press spacebar with them held in your cast chain and you'll get special effects. There are many such magicks, some of them game-breakingly powerful. HASTE and FEAR and METEOR SWARMS and mighty THUNDERBOLTS and CRASH TO DESKTOP (not kidding, that is a spell) and 5-5-5-DEATH (also a spell)
Who wants to play some co-op Magicka?
