Colossal skeleton

Ruby. Unless the colossal skeleton’s ruby is destroyed after it hits 0 hit points in 24 hours it will regenerate with full stats.

The colossal skeleton can make one grab or ribsnag attack and one jawbone attack or two bonesword attacks.

Grab. Grab attack +10 to hit, reach 10ft, 1 target. Hit: 15 (3d6 + 4) [force] damage if the creature is large or smaller then it is grappled must make a DC 16 CON saving throw or be grappled.

Bonesword. Melee Weapon Attack: +10 to hit, reach 10ft., up to 2 targets. Hit: 24 (3d10 + 7) [piercing] damage.

Jawbone. Ranged weapon Attack: +8 to hit, range 40/50 ft., 6 targets. Hit: 14 (2d8+ 8) [bludgeoning] damage.

Ribsnag. If a creature is grappled and the rib cage is not already occupied then it can open it’s ribcage and trap a creature and it cannot do anything until it’s freed. Every round a creature who is captured ends in the ribs take 16 (4d6 + 4) [force] damage and if they die in his ribs he gains 20 permanent hit points. If two ribs take 15 damage the ribs break and the creature is freed and the colossal skeleton has to wait one round for the ribs to regenerate.

Skeletal army (Costs 2 Actions). Once per day the colossal skeleton can shove his bonesword into the ground and call forth any skeleton within 5 miles of him to serve him until they die.
