Strength by game phase

Passive, spells and ultimate

Assassin's Mark (P)

Dealing spell damage to a champion creates a ring of energy around them. Exiting that ring empowers Akali's next Attack with bonus range and damage.

Tips to maximize your impact

Poke through a minion
Cast Ice Shard (Q) through a minion: the spear shatters on it, and its shards damage and slow the champion behind.
Flank with your claw
Engage from the flank with Glacial Path (E): recast it to blink to the claw, then root nearby enemies with Ring of Frost (W).
Ult yourself if you get focused
If you're getting focused, cast Frozen Tomb (R) on yourself: you become untargetable for a moment, heal based on your missing health, and the ice slows enemies around you.
Fight where they fall
Stay in the heart of teamfights: Iceborn Subjugation (passive) turns an enemy champion who dies near you into a Frozen Thrall, which slows, then explodes.

How to counter and exploit weaknesses

Trade after her smoke
Take a trade once Twilight Shroud (W) is used: she can't vanish again until its 20 to 16 second cooldown is over.
Play hard before she hits 6
Play hard before she hits level 6: without Perfect Execution (R), her only spell to get back on you is Shuriken Flip (E), on a 16 to 10 second cooldown.
Fire into her smoke
If you have AoE spells or skillshots, throw them into the Twilight Shroud (W) smoke: they hit her even while she's invisible, whereas targeted spells can't be cast on her.
Punish her when she's low on energy
Take a trade when she has just cast Five Point Strike (Q) several times: each cast costs 110 to 70 energy depending on rank, from a base pool of 200.
Hit her between her two dashes
Hit her right after the first dash of Perfect Execution (R): she has to wait a moment before she can cast the second.
