Sabre tooth Cave Spider.
For Dungeon Crawl Classics and other D20 based RPGs.
This monster lurks in caves and other semi-subterranean areas, preferring mostly large game as its meal. This spider is roughly the size of a lion or similar large cat. If cornered or outnumbered, it will retreat to its lair, usually nearby.

The sabre tooth cave spider will always attempt to attack from the shadows, attempting to paralyze its prey before dragging it off to be eaten. It prefers to Pounce from a short distance to catch its prey off guard. If this attack is successful, the spider immediately gets its regular attack on the target for free. It rarely attacks more than two or three creatures, especially if man-sized or greater.
At the Judge’s discretion, there could be as many as 3-5 of these spiders operating together in a single area. They share the risks as well as the prey. If the target is large enough, two of these spiders have been known to take down the same target.
