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 , and .
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 .
- Invulnerability (e.g. ) and will block all damage to a target champion, including true damage.
- Using ( ) can dodge true damage from on-hit effects and true damage from standard attacks.
Countering true damage
- Building health causes sources of flat true damage (e.g.
) to effectively deal a lesser percentage of total health. This only partially applies to and , because these scale based on maximum health.
- Reducing Vayne's attack speed (via items such as or ) mitigates damage from 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.
- For each Silver Bolt proc, bonus health is effectively equal to (1 - % True damage) * (bonus health). For rank 5 , 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 damage output, contrary to popular belief.
- Shields such as 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 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.
