Elites

Elites are special enemies that only appear on certain waves. If any elites will spawn in a run the the player will be notified in the Shop. No elites will spawn in dangers 0, 1 or 2 but 1 wave can have an elite enemy on dangers 2 and 3 and a maximum of 3 waves can have a elite on it on dangers 4 and 5. If you kill an elite then it will drop a red Crate with a guaranteed drop of a legendary item in side of it.
