Rooting (Enchantment) [Earth]
Level: Druid 4
Mana: 6. No AoO. Base Success: 95%.
  Casting this spell attunes the druid mystically to the earth or stone he is standing on, rooting him to the spot and bestowing the endurance of Therya itself. The druid gains a +10 natural bonus to his armour rating versus slashing, piercing and blunt damage, as well as immunity to knockdown, stunning, knockback, teleportation and critical hits. The effects last until the druid moves.
