Size

• Numerical size (1-3) helps determines melee range, target for missile collision and obstacle collision.
• Descriptive size (small, medium or large) can determine chance of applying Knockback, and sprite size of a Grim Ward.
• Cannot infer anything from sprite size.

Unit size

Fangskin (size 3) is too large to follow the Werebear (size 2, despite his sprite size) up the stairs. If there were any size 3 monsters in the Arcane Sanctuary other than the The Summoner, they would have a similar problem.
