How to play Senna in ARAM Mayhem

Senna is a below-average pick in ARAM Mayhem on patch 26.21: tier C, #162 of 173 champions, with a 45.7% win rate over 2,203,305 games. It is also one of the most picked champions, showing up in 10% of games, so expect to see it on both sides.

87% of Senna's damage to champions is physical, so enemy armor is what slows it down. It keeps its team alive with 4,331 healing on teammates in an average game; stay behind your frontline and save it for the fights that matter.

Most Senna players go Crit (53% of games), but the On-hit path, on-hit attack speed items, is ARAMKit's top-ranked build: Sword of Blossoming Dawn, Statikk Shiv and Runaan's Hurricane, with a 49.1% win rate. On this build 49% of players skip boots and spend the slot on another item.

The cards that do best on Senna are Stackosaurus Rex, Windspeaker's Blessing and Hand of Baron. Cards built around healing yourself fill most of the top of its list, followed by healing and shielding allies. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Glass Cannon and Bread and Cheese when you can: they do worst on Senna. A pair to look for: Protein Shake with Enchanting Butterflies.

Take Flash and Cleanse (0% of players); Ghost is the common alternative. Max Q (Piercing Darkness) first, then W, then E.
