Rapidfire Emblem

Damage that bypasses Armor and Magic Resist — the damage number on the source is applied directly to current Health. Shields still absorb true damage like any other damage type.

Damage calculated as a percent of the target's maximum Health rather than from the source's own stats, so it scales with how much Health the target stacked — the standard answer to a high-Health frontline. Two flavors: the Burn keyword (a percent of max Health as true damage every second) and burst hits that take a percent of max Health in a single instance. Because the number is a percent, extra max Health buys no extra effective Health against it.

Bonus Attack Speed makes a unit attack more often per second, which means more auto-attack damage and faster mana generation toward the next ability cast. Some carries scale beyond that — their ability itself fires more hits when they have more Attack Speed (e.g., the number of swipes in Aphelios's onslaught). Stacking AS items and traits on these units compounds: faster autos, faster casts, and bigger casts.

Effect fires on each basic-attack hit — every auto procs items like Red Buff (burn/wound), Nashor's Tooth (mana on attack), and Kraken's Fury (stacking Attack Damage per attack, up to 15). On-hit carries scale with attack-speed buffs, so stacking AS multiplies their damage and utility per second.
