Scroll: Runeskin I

Enchant your body with a magical barrier that passively builds up to 3 stacks. When you receive damage, Runeskin will absorb 50% of the damage and lose 1 stack. Runeskin's stacks will replenish at a rate of 1 stack every 10 seconds, as long as no damage is received during that time. Once the stack count reaches 0, no damage absorption will occur.
