Walls: Tips and Tricks

To create a simple Stone Wall you need at least two Elements: Shield + Earth (ED). It lasts for 8,5 (Shield 7 sec / Earth 1,5 sec) seconds. Each addtional Earth Element adds another 1,5 seconds to max. duration of 13 seconds (EDDDD).

With exception of Lightning you could add any other Element to your Wall. For example a Fire Stone Wall (EDF). It lasts for 8,5 seconds and does Fire damage. Using this Combination (EDDFF) creates a Fire Stone Wall which lasts for 10 seconds and does twice the Fire damage.

Cast Spell (Forward) = Creates a semi circle wall.
Cast Spell (Area) = Creates a full circle wall.
Imbue Weapon = Creates a wall in a straight line in front of you.

I found out that you could heal your walls to increase its longevity using Heal Beams, Balls and Area Spells. Each Heal Element you cast on our Walls increases the longevity for 0,5 seconds.
NOTE: Walls can still be broken by enemies, projectiles etc.

Area Cast Heal

This Arcane Stone Wall (EDDSS) lasts for 10 seconds. Using Heal (WWWWW) Area Cast adds addtional 3 seconds to its longevity. You can repeat this as long as you want and your Wall will stay.

Healing Ball

You can also use Healing Balls (DWWWW) to heal Semi Circle Walls which add additional 2,5 seconds each time they hit.

Healing Beam

Using a Healing Beams (WWWWW) you can keep one or two parts of your Wall.

Area Prism

You could also heal a Full Circle Wall with Area Prism (WWWWW and Hotkey 2). It's a Magick you can unlock with completing Trails or Challenges.

Imbue Weapon + Area Prism

This Ice Stone Wall (EDDQR) is created with Imbue Weapon and healed with Area Prism. It blocks Projectiles and reflects Beams. It's very usefull in all variations when fighting against your friends. Have Fun!

There are a lot of small paths in Magicka 2 where you can trap and kill enemies and friends with walls. Hope you find this guide helpful. If there's something to add or to correct just write it in the comments.
