True damage is one of the four types of damage in League of Legends, the others being magic damage, physical damage and pure damage (which is only used by the fountain turrets). True damage ignores armor and magic resistance, as well as other forms of damage reduction such as Unbreakable, Unbreakable Will and Vengeful Maelstrom.
Blocking true damage
- Abilities or summoner spells which deal true damage are still blocked by effects that prevent damage such as the passive on Sivir's Spell Shield, Nocturne's Shroud of Darkness. ,
- Standard Attacks which deal additional true damage are still capable of being blocked by Pantheon's Aegis Protection.
- Kayle's Intervention will block all damage to a target champion, including true damage. Kindred's Lamb's Respite will block all damage to any champions below 10% of their maximum health in the area of effect, including true damage.
- Before the removal of Dodge, both true damage as an on-hit effect and true damage on standard attack were capable of being avoided completely if the standard attack was dodged, however during the effect of Counter Strike, Jax can still effectively dodge true damage from on-hit effects and true damage from standard attacks.
- damage over time true damage passive Trial by Fire and the debuff from Fiora's Duelist's Dance and Grand Challenge. and corresponding and are also capable of preventing and cleansing
Countering true damage
- Building health causes sources of flat true damage (e.g. Cho'Gath's Feast) to effectively deal a lesser percentage of total health. This only partially applies to Vayne's Silver Bolts, because it scales based on maximum health.
- Reducing Vayne's attack speed (via items such as Silver Bolts by reducing how often it procs. The bonus resist/health also diminish physical damage effects, which usually comprise the large majority of Vayne's total damage. or ) mitigates damage from
- For each Silver Bolt proc, bonus health is effectively equal to (1 - % True damage) * (bonus health). For rank 5 Silver Bolts, this means Bonus Health over 12 autoattacks remains 87% effective—still quite efficient. For all the above reasons, health constitutes an essential aspect of efficiently countering Vayne's damage output, contrary to popular belief.
- Shields such as Janna's Eye of the Storm absorb true damage and do not count towards max health; therefore, they protect equally well vs. all sources of true damage.
- Magic-only shields such as Morgana's Black Shield and the passive on and will have no impact on true damage.

- 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 its hitpoints.
- The Nexus Obelisk at the heart of a team's base, contrary to popular belief, does 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.

- True damage is not amplified by the mastery Executioner.
- As of patch V3.15, true damage is no longer amplified by abilities such Swain's Torment and Talon's Cutthroat.
