At 3rd level, you gain proficiency in one of the following tools; Carpenter's Tools, Glassblower's Tools, Mason's Tools or Smith's Tools.
Starting at 3rd level, when you make a melee weapon attack and hit an object or creature made of inorganic material such as stone, crystal, or metal, you deal an extra 2d6 damage to the target.
This damage increases when you reach certain levels in this class, increasing to 3d6 at 5th level, 4d6 at 10th level, and 5d6 at 15th level.
This would stack with crits and the double damage from tools.
Starting at 3rd level, when you reduce an object to 0 hit points using a weapon attack, you may use a bonus action to make one additional weapon attack or to take the Dash action (your choice). The target object must be 5ft or greater in at least one dimension, the object can be a section of a larger structure (such as a wall or ceiling).
Starting at 7th level, when you hit an object or creature with a weapon, you can use a bonus action to cast the shatter spell centred on the target. Strength is your spellcasting ability for this spell, and you take no damage from this casting.
You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses each time you finish a long rest.
