Mason

You have spent years of sweat and energy building up the cities around you. You gain the following benefits:

• You gain expertise in Mason's Tools
• You can create brick or stone structures at a rate of 15 cubic feet per day in an 8 hour shift, with an additional 5 cubic feet for every 4 hour period beyond the initial 8
• You may use a bonus action to make an Investigation roll with advantage on any stone or brick structure. On a DC 15 or higher you learn the weakness of the structure and when you roll a critical attack against the structure the total damage is multiplied by 2 instead of just the damage die (stacks with demolition ability of Mason's Tools)
