In Dota Auto Chess, your courier unlocks new experience levels that grant you various upgrades. There are two ways of getting XP:
- You get 1 XP automatically at the start of a round.
- You can spend 5 gold coins to get 4 XP. The button for purchasing XP is on the right side of your courier's panel. You can also press the "F" key. Try to purchase XP once you get 50 gold coins and a strong army. Usually, this is a much better choice than rerolling new heroes.
What you get by gaining new levels?
Your level determines the number of units placed on the board at the same time. On level 1 you can only place 1 hero. On level 9 you can use 9. The table below shows how much XP you need to get to level up.
