Rell

Not many supports go all-in on engage the way Rell does. The Iron Maiden runs on Ferromancy, and its centerpiece, Crash Down, is a mount-and-dismount mechanic that swaps speed for brute frontline weight. While mounted, she moves quickly and hunts for an opening. When she dismounts, she slams into the ground in her armor, launching nearby enemies into the air, gaining a big shield, and receiving bonus armor, magic resist, attack speed, and range, but also becoming slow and impossible to move. Rell’s whole identity rests on that exchange: once she commits, the fight takes place wherever she lands.

Her passive, Break the Mold, gives her unexpected bite for a tank. Her basic attacks and abilities add bonus magic damage and strip armor and magic resist from targets they hit, so the longer she stays in contact, the sturdier she becomes while her opponents grow more fragile. Shattering Strike is an uncommon addition to the tank toolkit: it destroys shields outright and stuns every enemy along a line, which makes it especially painful against shield-heavy compositions.

Full Tilt handles her approach. It gives Rell and a chosen ally a surge of move speed that intensifies as they close on enemies, turning a bot-lane pair into a battering ram. The reward comes from Magnet Storm, a burst of magnetic force that pulls nearby enemies toward her and keeps dragging them inward while inflicting damage over time. It ranks among the best teamfight-setup ultimates for supports.

Rell is a fit for players who like controlling when the fight begins. She stacks crowd control, draws attention away from her carries, and bunches enemies together for them. The downside is that a badly timed Crash Down leaves a slow, dismounted tank with no way out.
