Power Points are primarily obtained from Brawl Boxes. Each box will contain a small amount of Power Points for a random Brawler that you have unlocked. The Rarity of a Brawler does not affect how often a box contains Power Points for it; once you have unlocked a Brawler, a box has an equal chance of containing Power Points for it as any other Brawler.
In the shop, each Power Point costs 2 Coins. For example, 10 Power Points will cost 20 Coins, 32 Power Points will cost 64 Coins, etc. The amount of Power Points you can buy varies with the Daily Offer. Each Power Point offer can only be bought once. Power Point offers change every 24 hours, and after that, they can be bought again. In the form of a special daily offer, 160 Power Points can be bought once for 29 gems for any brawler that the player currently owns.
Some Trophy Road rewards offer Power Points as well. These rewards come in packs of 25, 50, 75, 150, or 200 Power Points and allow you to choose which Brawler to give the Power Points to.

Once you have enough Power Points for a Brawler's level, you can spend Coins to upgrade it to the next level, all the way up to level 9. Each level increases a Brawler's health and damage by 5% linearly.
After enough Power Points to get a Brawler to level 9 are collected, excess Power Points will be automatically converted to Coins at the exchange of 2 Coins for every 1 Power Point. For example, if you only need 2 more Power Points and you get 5 Power Points. The remaining 3 Power Points will be converted into 6 Coins. This means that the more fully maxed Brawlers you have, the more coins you will see coming when opening boxes.
To get a Brawler to level 10, you must obtain one of its Star Powers. To find a Star Power, your Brawler must be at level 9. Star Powers are found in Brawl Boxes, or they can be bought for 2000 Coins in the Shop when they appear. Getting both Star Powers for a Brawler does not upgrade them to Level 11; they stay at Level 10.
