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.

Blocking true damage

• Abilities or summoner spells which deal true damage are still blocked by spell shields.
• Standard Attacks which deal additional true damage are still capable of being blocked by Pantheon's Aegis Protection.
•  Invulnerability (e.g. Kayle's Intervention) and Fiora's Riposte will block all damage to a target champion, including true damage.
• Using Counter Strike ( Jax) can dodge true damage from on-hit effects and standard attacks.

Countering true damage

True damage cannot be mitigated or reduced, but there are three possible ways to cope with it.

• Stacking health causes sources of flat true damage (e.g. Cho'Gath's Feast) to effectively deal a lesser percentage of total health.
• Reducing the instances of damage that apply true damage. This especially applies to sources that scale based on maximum health, like Vayne's Silver Bolts, which are greatly hindered by effects like Cold Steel and/or the cripple effect from Frozen Heart.
• Shields to absorb the true damage, such as Soul Furnace and Janna's Eye of the Storm.

Notes

• 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 and Sion's Glory in Death self-inflicted damage do not deal true damage, but pure damage, which is similar to true damage in that it ignores all forms of resistances but also has the caveat of ignoring damage immunity, shields and death prevention buffs. Furthermore, it will not flag the champion recieving such damage as 'in combat', or be tracked by statistics such as the Death Recap or end-of-game statistics.
• True damage is unaffected by damage reductions such as Exhaust.
• True damage is not amplified by damage modifiers from runes such as Coup de Grace, Cut Down and Last Stand.
• As of patch V3.15, true damage is no longer amplified by abilities such Zed's Death Mark and Vladimir's Hemoplague.
