How to get XP and level up in Teamfight Tactics
The backbone of your team’s strength is your level, which directly affects the number of units you can have on the board and the chances of being offered higher rarity units. There are two ways to gain XP: The 2XP you are automatically given each round, and the 4XP boost you can purchase for four gold.
For most of the game the two XP a turn is enough for passive progression, but there are certain points in the game where spending a little extra can put you at a major advantage. At any point when you are 4XP away from levelling up, you should absolutely spend that money.
For each level you gain – up until the max of level nine – you are allowed an additional unit on the board, so lagging in levels is lagging in firepower. Nothing spells disaster like being outnumbered, and the occasional loss of a few gold is worth it if you avoid a significant dent in your HP.
It also means the opportunity to grab powerful champions is reduced. You can’t even begin to earn rare, epic, and legendary champions until you reach a certain level, and once you do reach that level the chance of getting said champions increases the higher level you are. In order to create the best team possible, you must keep an eye on your level and invest in XP.
