Frag grenades do 3d6 fire damage that can degrade organic armor and destroy scrolls and potions, while gas grenades do 3d6 poison damage to any monsters that are not poison resistant. The explosion of a grenade on its own will create a blast radius, a 3 x 3 square (the same form as a fireball) centered on the grenade's landing point. Multiple grenades exploding on the same square may produce a larger blast radius. Also note that exploding grenades will destroy bullets lying on the ground. If an armed grenade explodes in your inventory, you'll take damage despite any resistances you may have.
Grenades will become armed when they are thrown or applied. Note that applying a stack of grenades in your inventory will arm the entire stack. A grenade will explode one to six turns after having being armed, depending on its BUC status:
- Blessed: 4 turns
- Uncursed: d2+2 turns
- Cursed: d5+1 turns
Cursed grenades additionally have a chance to not arm at all. The first turn in the above counts includes the turn taken arming the grenade. Note that the better the BUC status of the grenade, the more reliable its fuse length. Armed grenades can be kicked or picked up and thrown at other targets. Grenades launched from a grenade launcher will explode on impact. The impact of a grenade always does 1-2 points of damage prior to the explosion.
Grenades are not generally very useful weapons. They are heavy, and as compared to other firearms, they do comparatively little damage. A grenade launcher does little to ameliorate this situation, and is little better than throwing them. As a threat to the player, they are rendered harmless by fire resistance and poison resistance, both of which one is reasonably likely to have before meeting soldiers. Their main danger is that they can burn armor, and they destroy bullets on the ground. The latter can be a serious impediment to building up a large collection of bullets, so one should try to gather bullets quickly, and toss away any grenades that are thrown near them. Grenades are also useful to sell to shopkeepers, since they are relatively valuable and appear in good-sized stacks.
Other things about grenadesEdit
Throwing a grenade into water, then seeing it explode causes the message: "You see a plume of water shoot up". If by some way you are fast enough to arm a grenade, drop it in a pit and fill the pit with a boulder, you will "hear a muffled explosion". This message is also shown when a frag grenade explodes in a container.
