Creature Level Loot control

Loot drops increase with the Stars on a Mob, and which world it is in.
The chance of a Trophy also increases with Stars, except for Bosses where a Trophy is guaranteed regardless of stars.
Multi Star Bosses drop more secondary loot

Roughly speaking , more risk = more reward.

The Colour of the Stars matter
