True damage

For the virtual band and associated content, see True Damage

True damage is one of the three types of damage in League of Legends. True damage ignores armor and magic resistance, as well as other forms of damage reduction such as Unbreakable Will, Unbreakable, Shield of Durand, Primal Howl, and Defiant Dance. True damage can be dealt as a DoT (Damage over time).

Blocking true damage

Abilities or summoner spells which deal true damage are still blocked by spell shields.
Parries can block the true damage from basic attacks and on-hit effects.
Invulnerability (e.g. Kayle's Divine Judgement) and Fiora's Riposte will block all damage to a target champion, including true damage.

True damage cannot be mitigated or reduced, but there are ways to deal with it:

Stacking health causes sources of flat true damage (e.g. Ignite) to effectively deal a lesser percentage of total health.
Shields that absorb true damage (white), such as Barrier, Sion's Soul Furnace, and Janna's Eye of the Storm.
Invulnerability which blocks all types of damage, such as Stopwatch or Kayle's Divine Judgement.

Despite popular belief, champions whose abilities have health costs associated with them do not deal true damage to themselves when they use an ability which requires health to cast.
- This can be evidenced when they have an absorption shield on them, when they use their health-based ability, the cost of it penetrates the shield and directly drains the health of the user, in contrary to true damage that has to break any absorption shield on the target to reach their health.
The Nexus Obelisk deals an unique form of true damage^[1] that additionally bypasses every damage-event related effect in the game, including shields, damage transfers, death immunity, untargetability and invulnerability effects. Furthermore, since it doesn't register as a damage event, it will not flag the champion with 'in combat' status, with some exceptions.
True damage is unaffected by damage modifiers (i.e Exhaust, Coup de Grace).
As of patch V3.15, true damage is no longer amplified by abilities such Zed's Death Mark and Vladimir's Hemoplague.
