There's a fire gremlin creature.
Attack 3, defense 2, speed 4, initiative 10, 6 HP, 5 shots.
Compared to the regular improved gremlin, it has +1 attack, -2 shots, -1 speed, -1 initiative, and -1 skill.
Compared to the pest gremlin, it's even worse: -2 attack, -2 defense, -2 shots, -1 speed, -2 initiative.
Also, the standard improved gremlin has 1 repair, while the pest gremlin has infinite sabotage.
The fire gremlin has only 1 fire mark (2 shots less), which doesn't do much damage. It's weaker in stats and speed.
But it has a growth of 10 instead of 20.
I would understand if it could set things on fire infinitely or 20-50 times, but how did it end up like this?

and yes, in its original form, it refused to accept magical artifacts, but I fixed that for myself.
