Deadlier Blades

Scales with Attack Damage (AD). Champions and effects flagged as AD-scaling get bigger auto-attack and ability damage when the holder stacks AD from items like Deathblade, Infinity Edge, Giant Slayer, and Bloodthirster, or from trait bonuses.

A reward that puts an item straight into your hands, outside the usual ways of earning one. You do not win it off a carousel, open it out of a loot orb, or pick it from an anvil offer -- it simply arrives. What arrives varies: a basic component, a finished item, or a short-lived one that lasts a single round and then goes away. Augments and wisps are the main sources. Some of them keep paying out after the first gift, handing you more once your champions have attacked, taken damage, or fought a set number of rounds.

Effect fires when a unit secures a kill or assist. An assist counts, so a unit that only contributed damage still triggers it.

A stat that ratchets up round after round instead of resetting when the fight ends. The usual trigger is a takedown — the carrier banks a stack on every kill or assist and keeps it, so early-round farming compounds into late-game power — but the trigger is not always a takedown you made. Old Growth pays out whenever any enemy dies within three hexes of it, handing your strongest Old Growth champion 30 permanent max Health each time, and Veigar banks Ability Power when the enemy it hit dies. What every source here shares is the persistence, not the kill: the stack survives the round, which is what separates it from in-combat stacking that starts again from zero every fight.
