Giant, Thursir Armorer

Forged Forgery. Thursir armorers wear armor forged from dwarven armor and shaped to resemble dwarven armor. Skilled blacksmiths can recognize and exploit this design quirk. When a creature proficient with smith's tools scores a critical hit vs. thursir armorer armorer's armor breaks reducing armorer's AC by 5 until armorer repairs armor. If armorer is critically hit by any creature while its armor is broken armor shatters and is destroyed reducing armorer's AC to 12.

Multiattack. Uses Flinging Smash if available. Then two Battleaxe attacks or one Battleaxe and one Shield Bash.

Battleaxe. Melee Weapon Attack: +8 to hit, 10 ft., one target, 14 (2d8+5) slashing damage or 16 (2d10+5) slashing damage if used with two hands.

Shield Bash. Melee Weapon Attack: +8 to hit, 10 ft., one target, 10 (2d4+5) bludgeoning damage and the target must make DC 16 Str save or be knocked prone.

Flinging Smash (Recharge 5-6). Makes sweeping strike with shield. Each creature within 10 ft. of armorer: pushed up to 15 ft. away from it and knocked prone (DC 16 Str negates push and prone).

Runic Armor (3/Day). Can inscribe the thurs rune on its armor. When a creature hits armorer with melee weapon attack while rune is active creature takes 4 (1d8) lightning and can't take reactions until start of its next turn. Rune lasts for 1 min.

Harness Dwarven Soul. Draws on the soul fragment trapped in one of the dwarven skulls on its belt. Armorer has advantage on ability checks when using smith's tools and on attack rolls using a battleaxe handaxe light hammer or warhammer until start of its next turn. It carries six skulls on its belt.
