On page 111, the radius of burning pitch scattered by a light catapult is given at 5’, and a large at 10’. The respective damage is given as 1d6 and 2d6. I think there’s an argument that the latter damage should be 4d6: That reflects the ratio of affected area more accurately, and gives the Gamemaster an easier way to measure decreases in damage of the fire is being put out (per 5’ radius segments extinguished).
This is not a bump: I just noticed that the 1d6/2d6 damage for pitch is listed under the Catapult description in Ship-to-Ship combat, but the catapult entry in the equipment section lists the damage as 3d6/4d6 (ie, doesn’t have damage for burning pitch). Minor discrepancy.
