Commanding Presence. Wyrmwiest has a commanding aura around him that helps bolster his allies. All allies within a 5ft radius have advantage on melee attacks against their enemies.

Adamantine Plate. All critical hits against Wyrmwiest are treated as normal hits. 

Stone Camouflage. The gnome has advantage on Dexterity (Stealth) checks made to hide in rocky terrain.

Gnome Cunning. The gnome has advantage on Intelligence, Wisdom, and Charisma saving throws against magic.

Innate Spellcasting. The gnome’s innate spellcasting ability is Intelligence (spell save DC 11). It can innately cast the following spells, requiring no material components:

At will: nondetection (self only)

1/day each: blindness/deafness, blur, disguise self

Berserker Battleaxe. Melee Weapon Attack: Attack: +9 to Hit (1d8+5 Slashing)(1d10 Versatile) 

You gain a +1 bonus to attack and damage rolls made with this magic weapon. In addition, while you are attuned to this weapon, your hit point maximum increases by 1 for each level you have attained.

Curse. This axe is cursed, and becoming attuned to it extends the curse to you. As long as you remain cursed, you are unwilling to part with the axe, keeping it within reach at all times. You also have disadvantage on attack rolls with weapons other than this one, unless no foe is within 60 feet of you that you can see or hear.

Whenever a hostile creature damages you while the axe is in your possession, you must succeed on a DC 15 Wisdom saving throw or go berserk. While berserk, you must use your action each round to attack the creature nearest to you with the axe. If you can make extra attacks as part of the Attack action, you use those extra attacks, moving to attack the next nearest creature after you fell your current target. If you have multiple possible targets, you attack one at random. You are berserk until you start your turn with no creatures within 60 feet of you that you can see or hear.

2 per round.
