Attack of Opportunity

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.

Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

Shield Block

Trigger The monster has its shield raised and takes damage from a physical attack.

Effect The monster snaps its shield into place to deflect a blow. The shield prevents the monster from taking an amount of damage up to the shield's Hardness. The monster and the shield each take any remaining damage, possibly breaking or destroying the shield.

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 20 feet

Melee Lance +20 (deadly d8, jousting d6, magical, reach 10), Damage 2d8+12 piercing

Melee Claw +20 (agile, finesse, unarmed), Damage 2d4+12 slashing

Lancer

The skeletal knight uses a lance in one hand, even when it isn't mounted. If the skeletal knight critically hits a creature with its lance Strike, the target is Clumsy 1 until the start of the skeletal knight's next turn.
