Tower of Doom/Weapons and Treasure

Weapons
Colors

For hand-held weapons, the color of the weapon indicates its power.

For projectile weapons, the color of the weapon indicates the number of shots remaining in that weapon. As that number decreases, the weapon will change color; however, each color can "hold" for up to four shots, and seems to vary between weapons, so it can be difficult to tell exactly how many shots remain, but the maximum number of shots per weapon is approximately 16.

The Axe, Hammer, and Spear can be used in both hand-held and projectile combat. It's unclear whether using them as projectiles makes them weaker as hand-held weapons, but given that they change color when fired as projectiles, it seems likely.
