Give your first character that dies each brawl +2/+1 permanently.
Charon is one of the advanced Heroes in Storybook Brawl.
After the first few rounds, there are very few battles where you don’t have at least one Character die. So Charon pretty much has a permanent +2/+1 buff guaranteed each fight. The trick is making sure that it goes to the right Character.
As of game release 0.63.4, Coin of Charon will no longer waste its buff on a Level 1 token such as a statue produced by Medusa.
