Spackals are small canines that stalk praries, deserts, and badlands, but they sometimes venture in to urban areas and Ancient ruins.  They have milky-gray eyes and sticky, matted fur.

When attacking, spackals spit globs of quick-drying adhesive mucus at their prey at a range of up to 15'.  Each successful hit reduces both a victim's Strength and Dexterity by -3, and Movement Rate by -40' -(15').  These reductions impact appropriate Ability Modifiers (ex: a 16 STR reduced to an effective 7 drops a +2 bonus to a -1), and if values drop to 0 (or below), that Ability is unusable—0 STR prevents melee attacks, 0 DEX prevents ranged attacks, and 0' (0') Movement means the target is stuck in place.

When a target is entombed and rendered helpless, spackals close in for the kill.  Their saliva contains a compound that dissolves the paste-like adhesive, so they can devour their prey alive...bite by agonizing bite. 

The paste disintegrates naturally in one hour, and assuming they're still alive, a victim's Abilities return to normal.

Some tribes collect spackal saliva and for use on the tips of arrows and bolts, as the liquid adds an additional +1d3 acidic damage.
