IP Influence Points


IP Influence Points, or IP IP, are a measure of a summoner's influence in the League of Legends rewarded based on their performance on the Fields of Justice. The amount of IP rewarded per match varies on whether it was a win or a loss, game type, and length of match. Influence points can be used to permanently unlock champions, runes, or additional runebook pages in the Riot Store.

Determining Factors

Since patch V1.0.0.111, the amount of Influence Points awarded for a given match depends on these rules:

  • It increases linearly with the duration of the game.[1]
  • For each Field of Justice there is a floor and cap for IP gained per match.
    • Games longer than the cap or shorter than the floor grant the same IP as a game with length corresponding to the length of the cap.
    • The floor does not apply to Co-op vs. AI games, the cap is not tested.
    • On Summoner's Rift these lower and upper limits are at 25 minutes (76 IP for a win) and 55 minutes (145 IP for a win).[1]
    • On Twisted Treeline the floor is at 20 minutes (64 IP for a win) and the cap is at 55 minutes (145 IP for a win).
    • The precise limits for the Crystal Scar are not known, the floor seems to be 7 minutes, additional testing is needed. It was previously believed to be 20 minutes as surrender is available at 15 minutes similar to the Twisted Treeline.
    • The cap is different on ranked games. IP boost grants 168 IP on ranked games on Summoner's Rift, so it appears the cap is 65 minutes for ranked games on Summoner's Rift.
  • For a win, the reward is approximately 18 IP + 2.312 per minute IP.[1]
  • For a loss, the reward is approximately 16 IP + 1.405 per minute IP.[1]
  • An active Wins IP Boost gives you a flat amount of IP equivalent to the minimum IP you could get from a game matching the duration of the cap (for whichever game mode you are playing).
  • A custom game has a penalty of 25%.
    • Custom games only grant IP when teams are balanced. (example: 2vs2, NOT 2vs3)
  • Co-op vs. AI and custom games have separate limit timers which reset daily, after 180 minutes for Co-op vs. AI and 120 minutes for custom games no IP is earned. These timers reset with your First Win of the Day timer, which can be checked on your summoner profile.
  • Twisted Treeline in Co-op vs. AI does not have a limit timer.
  • A win, in any game type except custom, will award the "First Win of the Day" bonus if available. This bonus is a fixed 150 IP which is not affected by boosts or penalties. When awarded, this bonus becomes unavailable for 22 hours.

Co-op vs AI Gamemode Modifiers

Co-op vs. AI matches have penalties depending on the summoner level and difficulty.

  • A game shorter than 7 minutes does not grant any IP and as such also no first win of the day. This may also apply to regular games, but is unlikely to happen.
  • The rule for minimum IP reward does not apply (a match shorter than 25 minutes will give less IP than a match of 25 minutes).
  • The rule for maximum IP reward does apply.
Summoner Level Beginner Mode IP/min Intermediate Mode IP/min
1 to 9 No penalty ~2.312 No penalty ~2.312
10 to 19 15% penalty ~1.965 No penalty ~2.312
20 to 29 30% penalty ~1.618 10% penalty ~2.081
30 45% penalty ~1.272 20% penalty ~1.850



Formula: { [base IP] + ([IP / min] * [game time in minutes]) * [gamemode modifier] } + [Dominion Bonus]

Field of Justice Summoner's Rift Twisted Treeline ARAM
[IP / min] (win) 2.312 2.312
[IP / min] (loss) 1.405 1.405

The game time is always rounded down, meaning a game of 35:59 grants the same amount as a 35:00 minute game.

The custom game modifier is 0.75.

You will earn 0 XP/IP when playing a custom game that does not have the same number of champions on both teams.

  • Runes can only be bought with IP.
  • Skins and bundles can be bought only with RP, not with IP.
  • The maximum/minium amount of IP  from a match is:
    • Win: (first win of the day bonus, 55+ mins ranked match, IP boost (timed and per win)) 150 + 168 + 168 + 168 = 654 IP (822 on a double-IP weekend)(1962 with a 5-man party in party reward weekend)
    • Loss (55+ mins match): 95 IP
