Oh I see, yes, so it is the same as the original 3.5e skill system... there is the misc mod column that could be used for synergy bonuses but I could look to see if there is a way to reliably build the synergies in... hmmmmm That said, it isn't nailed on enough to warrant hardcoding. I'd suggest using the suggested field above and managing that inclusion of that bonus situationally: In some cases, this bonus applies only to specific uses of the skill in question, and not to all checks. Some skills provide benefits on other checks made by a character, such as those checks required to use certain class features.
