What is the Highest Ranking Level in Fortnite?

Also max level for the season X level is 100. (forgot to add that)

Is Level 100 the max for Account Level also?

Level 100 is the max you can get every season.

Account level is your level from all previous seasons combined.

for example: if in season 3 you were level 15, in season 4 you were level 30, your account level would be 45.

Not only that, but a little bit more about the ranking system, every level requires more and more XP to get too, for example, from Level 1 to 2 is 500XP, but from 2 to 3 is 600XP.

The battle pass system is also a standalone entity in the sense that XP doesnt directly affect it, but leveling up does grant you battle stars, which are required to level up the battle pass tiers, (10 Battle Stars per Tier, 100 Tiers)

Hope this helped, have fun!

if you have any other questions relating to the tier and XP system, reply, and ill get back to you.

Also max level for the season X level is 100. (forgot to add that)

Season level max is always 100. Account level max can theoretically go up forever, until Fortnite stops being a game. Its whatever level you end on each season added up.

Your season X level is the level you are during the season and your account level is your overall level over the time you play fortnite.
