The Forges of Yorn are known for their magic like wonders, but do not be tricked. No magic is used to make these weapons and tools, just fine craftsmanship.
When attacking a creature wearing armor, treat this weapon as a +1 Warhammer. When missing an attack against opponents wearing armor, you can use your reaction to roll a D20, and on beating a 10, you create a weak point in the armor, giving you advantage on your next attack. On a 20, the armor is damaged, reducing the targets AC by 1.
Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Push. If you hit a creature with this weapon, you can push the creature up to 10 feet straight away from yourself if it is Large or smaller.
Notes: Bonus: Magic, Damage, Combat, Versatile, Push
