I know Two Trait Bonuses Don't Stack: But what about a +1 trait bonus to CMB and a +2 Trait Bonus to Trip (specifically)

[J.M. Perkins]

In this case, the two traits would be bred for war (human racial) and heirloom weapon with the plus 2 to a specific combat maneuver [trip](equipment trait)

[Alexander Kilcoyne]

No. Trait bonuses don't stack. The latter simply overlaps the former. This character is good at combat maneuvers and particularly good at trip.

[Eridan]

Both are bonuses to CMB. One for the general CMB and the other for a special CMB so they dont stack.

[J.M. Perkins]

Thanks for the clarification!
