Lower Spears! [>] to [>>>] Frequency once per round; Effect The skeletons engage in a coordinated longspear attack against each enemy within 10 feet (DC 27 basic Reflex save). The damage depends on the number of actions. [>] 2d8 piercing damage [>>] 3d8+8 piercing damage [>>>] 4d8+8 piercing damage.

Hurl Javelins! [>>] The troop's members throw a volley of javelins. Each creature in a 10-foot burst within 30 feet of the troop takes 2d6+10 piercing damage (DC 26 basic Reflex save). When the troop is reduced to 8 or fewer squares, this area decreases to a 5-foot burst.

Form Up [>]

Phalanx Charge [>>] Requirements The infantry is in a phalanx; Effect The skeletons lower their longspears and charge. The troop Strides in a straight line until they're adjacent to an enemy then use Lower Spears!, dealing 3d8+8 piercing damage. Any creature that fails its save is also knocked prone.

Troop Movement Whenever the skeleton infantry Stride, they first Form Up as a free action to condense into a 20-foot-by-20-foot area (minus any missing squares), then move up to their Speed. This works just like a Gargantuan creature moving; for instance, if any square of the infantry enter difficult terrain, the extra movement cost applies to all the guards.
