Grenade

A grenade is a small weapon typically thrown by hand. Grenades can create many different effects, from simple fragmentation explosions to loud concussive bangs, and from simple gaseous emissions to extreme localized temperature changes.

Frag grenade
Fragmentation grenades, often called frag grenades, are common grenades that contain a small but powerful explosive device.

Cryo grenade
A cryo grenade dramatically reduces the temperature within a short range, often staggering creatures susceptible to extreme cold.
