Little legends are a variety of creatures and chibi versions of champions that are controlled directly by the player. They are purely cosmetic and have no effect on gameplay.
The player can move them to pick up loot orbs from neutral monsters and additional orbs dropped from set mechanics or econ-generating traits. However, the Little Legend used has no effect on gameplay, though players often swear by a specific little legend.
Opposing players’ Little Legends will also show up on boards that they are scouting, giving information on which players are scouting which boards. On carousels, the size of the Little Legend will scale with the amount of HP that the corresponding player has (ie. a 100 hp Little Legend will be significantly larger than a 10 hp one).
