Speak with Rats (Sp): At will, a jermlaine can produce an effect like that of a speak with animals spell (caster level 3rd), except that it enables communications only with rats and dire rats.

Jermlaines attack only from ambush. If an ambush is impossible, they hide and wait until it is feasible. They always try to single out injured, ill, or sleeping foes as their first targets. Jermlaines enjoy sneaking into camps and vandalizing or stealing equipment, so long as they stand a good chance of getting away without combat.

Rather than confront an enemy, jermlaines prefer to dig pits or build net-dropping traps and other devices that can capture prey without a fight. Once an enemy is caught in a pit or net, jermlaines swarm over him, pummeling to cause subdual damage until the target is knocked out. They have also been known to pour acid or flaming oil over trapped foes that appeared to dangerous to approach directly, even while trapped.
