The Ultimate is the fourth ability of most Champions. The ultimate is considered a champion's defining ability and is oftentimes considered their strongest. Ultimates vary greatly between champions, with some having passive effects (Jax 贾克斯Grandmaster'sMight.png Grandmaster's Might), some having global effects (Karthus Karthus' Requiem.png Requiem), some being spammable from having low cooldowns (Kassadin Kassadin's Riftwalk.png Riftwalk), some being auras (Sivir Sivir's OnTheHunt.png On The Hunt) and some summoning other units (Annie Annie's SummonTibbers.png Summon Tibbers). Whether an ultimate is considered a champion's strongest ability or not, using your ultimate effectively is crucial to playing any champion. Ultimates are defined by being able to be taken at levels 6, 11, and 16.

It is also possible to tell whether or not an allied Champion's ultimate is ready or not, by the indicator. The indicator is the green dot which is placed right beside the respective champion's portrait on the left side of your screen. When the green light is on, the champion's ultimate is ready. If the light is off, the champion has either not learned the abilty or it is currently on cooldown.

There is currently only one champion that doesn't have an Ultimate: Udyr Udyr. He has four Stances that are all trainable up to level 5. Karma Karma's ultimate is also special, being available from level 1 and not requiring any skill points; instead, all her other abilities can be leveled up to 6. Jayce 杰斯Mercury Hammer Mercury Hammer and Mercury Cannon Mercury Cannon and Elise 伊莉丝Spider Form Spider Form and Human Form Human Form are available at level 1, but can still be leveled up at level 6, 11 and 16, making them special in having 4 ranks.
