What are the systematics for the Baldurs Gate Throne of Bhaal game To be more specific how is damage calculated

It's based on D&D rules, so each weapon has its set amount of damage dice such as a long sword's damage which is 1d8 (one eight sided die), and it randomly generates(rolls) a number between 1 and 8, then adds on your strength modifier which is increased by 1 point per 2 points starting at a 0 modifier at strength score 10 (there are negatives for a score below 10). Then if any magical enchantments are present they will be added on.
