Question

What does the moonbeam do?

Answer 1

MOONBEAM :

A spell like moonbeam affects a creature when the creature passes into the spell's area of effect and when the creature starts its turn there. You're essentially creating a hazard on the battlefield.

Moonbeam is a bright yellow with a subtle neon undertone. Depending on the light source or time of day, it may appear as a bright yellow on the walls. Visualize this color in your own space.
