Do these enhancements stack?
Thief Acrobat Trip Focus +3 to trip DC (and does this also work on Improved Trip?)
Fighter Kensei Tactics +3 to tactical feats' DC
Dwarven Tactics +3 to tactical feats' DC
Legendary Juggernaut Legendary Tactics +6 to tactical feats' DC
Before I make a character that has all of the above, could I please get a confirmation that they all stack together? And that Trip Focus works on Improved Trip as well as Trip?
