Bosses

The Director
Risk of Rain has a spawning system run by an AI named the Director. For the Director, each monster is a "card" with a certain cost. The Director is only allowed to choose between ~6 cards for each map and gains points at a base rate of 1/second on Very Easy. Point gain is increased as the difficulty increases. The Director follows these orders:

 Chooses a random card If the Director can afford 10x the card's cost, it is spawned as a blighted elite. (Phantasm) If the Director can afford 4x the card's cost, it is spawned as an elite. If the Director can afford the card's cost, it is spawned as a normal. If the Director can afford another card, it waits 1/4 of a second and spawns another one, up to 4. After the Director runs out of points, it waits 15 seconds to 1 minute to choose another card and start over.
