Upgrades Bramble Vest and Thornmail, increasing the armor stat of both items by 25 and empowering Thorns to generate a protective shell around you that grants 25% damage reduction. The shell is broken by the next enemy champion to use a basic attack on-hit against you, which causes them to take 50 to 250 (+ 30% armor) (+ 30% magic resistance) (+ 12% maximum health) magic damage. Shell regenerates after 20 to 5 seconds of being out-of-combat.
