Enlarge (Recharges after a Short or Long Rest). For 1 minute, the duergar magically increases in size, along with anything it is wearing or carrying. While enlarged, the duergar is Large, doubles its damage dice on Strength-based weapon attacks (included in the attacks), and makes Strength checks and Strength saving throws with advantage. If the duergar lacks the room to become Large, it attains the maximum size possible in the space available.

Axe of the Dwarvenlord. Melee Weapon Attack: +12 to hit, reach 5 ft or 20/60ft., one target. Hit: 11 (1d8 + 8) slashing damage, or 16 (2d8 + 8) slashing damage while enlarged or Hit: 12 (1d10 + 8) Slashing damage, or 18 (2d10 + 8) slashing damage while enlarged. When you attack a creature with this weapon and roll a 20 on the attack roll, that target takes an extra 14 slashing damage. Then roll another d20. If you roll a 20, you lop off one of the target's limbs, with the effect of such loss determined by the GM. If the creature has no limb to sever, you lop off a portion of its body instead. When you hit with a ranged attack using this weapon, it deals an extra 1d8 damage or, if the target is a giant, 2d8 damage. Immediately after the attack, the weapon flies back to your hand.

Invisibility (Recharges after a Short or Long Rest). The duergar magically turns invisible until it attacks, casts a spell, or uses its Enlarge, or until its concentration is broken, up to 1 hour (as if concentrating on a spell). Any equipment the duergar wears or carries is invisible with it.
