Tier I - Create wards and protections to preserve your units.
"The novice of the arcane is often captivated by spectacle, mistaking flame and storm for mastery. Yet the greatest magic is that which protects us from the forces of evil. No fire or lightning can undo a curse, no blizzard can fully shield those beside you, and no forbidden power will keep the ones you love by your side." - Merlin, the Tarnished Archmage
