Bombs are a resource crafted in the Laboratory and used by the Alchemist to be thrown.

Bombs are the ammunition needed for Alchemist units. When thrown, they have an area of effect which affects all units within the blast radius, and the units will sustain equal amount of damage, regardless of the distance away from the origin of the blast.

Bombs are considerably more damaging to bricks and structures than to enemy units. This is an intended mechanic to establish Alchemist's role as siege units.

To create bombs, you need 15 Brimstone. This requires Laboratory to be constructed.
