The Crossbow seems a bit low damage, should it not be D12s or 2d6 base damage since they are meant to be big castle defending weapons / 3 action reload?

Thanks for asking, The great arbalest grows its damage quite a bit on a critical due to deadly d6, allowing its max and average damage to be incredibly high. Especially if it has Striking runes. This paired with the Overpull feat make them a massive damage dealer! i did go back and forth on them a bit during development, if you would like to jump them to a d12 or maybe give them fatal d12 instead of deadly d6, I think those would also work wonderfully! If enough people agree i'll raise it to 1d12 base though!
