Arcane Shield

Spell Type: Defense; Mana Cost: 4 MP; TN: 14
Test: None; Requirements: Arcane Bolt

You create an arcane aura around you that deflects attacks. For one round, your Defense becomes equal to your Spellpower (10 + Magic + Focus). You can extend the spell’s effect when you cast it by spending 1 MP per additional round you would like it to last.
