Heartsteel, in 55.8% of games
Sunfire Aegis, in 43.3% of games
Thornmail, in 36.7% of gamesFrom 425 Amumu games on patch 26.20 and the patch 26.20 augment data.
You are your team's engage: go in first with Bandage Toss (Q), which has two charges, then land Curse of the Sad Mummy (R) on as many enemies as you can. Keep Despair (W) on through fights, since its max Health damage hurts tanks and keeps your Curse refreshed, so your magic damage deals bonus true damage. Heartsteel and Tank Engine push you toward stacking Health so you last longer in fights.
