A gas spore, e , can be dangerous for the unprepared. While they can't attack on their own and are rather slow, they act as a "living mine" exploding in a small radius when killed, therefore likely to kill your pet if it is too close.
The best strategy when faced with a gas spore is to step back and cast offensive spells, or shoot the gas spore with arrows, darts, or throwing rocks and junk weapons at them. If the cause of the gas spore's death is deadly poisoning, a death ray, or other effect that does not cause hit point loss, it will not explode.
You are responsible for any damage done by a gas spore explosion you cause. This has a number of repercussions depending on the monster that has been damaged:
- Pets killed by your gas spore explosion penalize you by -15 alignment and -1 luck.
- Peaceful monsters become angry at you.
- Shopkeepers, aligned priests, watchmen and other monsters that are best to avoid angering will cause you plenty of grief.
It is perfectly fine to simply avoid attacking gas spores altogether as they are incapable of attacking you. However, other monsters may accidentally cause a gas spore explosion with ranged attacks or an attack prompted by conflict.
If, however, no pets or other peaceful entities are nearby, and you have HP above 24 and/or a good AC, it might be best to dispatch of the spore with melee attacks, especially if you don't have a ranged weapon.
The attack by those who want to die
-- this is the attack against which you cannot prepare a perfect defense.
