Kruthiks for Holmes Basic (Converted from 4e)

The kruthik is a relatively obscure monster that first appeared in the miniatures handbook for 3rd edition, being a loosely veiled xenomorph stand in. Later, in 4th edition, they were added to the monster manual, being given a vague background and a less insect-like appearance.

Here is my take on this lesser known beast, converted from 4th edition for use with holmes basic:

Kruthiks are an ancient species of eusocial predators that dwell in the underworld, methodically exterminating anything in their way. Taking on the characteristics of reptiles, and insects, they are 4 legged creatures with small, vestigial limbs growing from their torsos, and mouth parts similar to ants. While they only have 4 legs like reptiles, their chitinous exo-skeleton and the way they grow seems more insectoid. Kruthiks hatch from eggs, laid in a central chamber of the hive, which hatch into the small, swarming, hatchlings. Given time, the hatchlings pupate, wrapping themselves in cocoons and emerging as adults. Some kruthiks undergo a similar metamorphosis, becoming hive lords, which lay eggs and direct the rest of the hive.

Fortunately for humanity, kruthiks are repulsed by sunlight, and only dwell beneath the earth. Legend has it the kruthiks are not a natural species, instead being created by a race of demons that lived on the earth untold eons ago.

Hatchlings are most commonly found within kruthik hives, and are usually near the deadly hive lords. While they are much weaker than adult kruthiks, they tend to outnumber foes significantly.

Hit Dice: 2

Adult kruthiks can spit acid once per day, with a range of 100 feet. Anyone targeted by the kruthik must make a saving throw against dragon breath or take 2d6 damage.

Kruthik Hive Lord

Hive lords collect the shiny objects given to them by the other kruthiks, meaning that while individual kruthiks usually don't have treasure, the hive lords might. Like their lesser brethren, hive lords can spit acid once per day with a range of 100 feet. Anyone targeted by the hive lord must make a saving throw against dragon breath or take 4d6 damage.
