Combat Maneuvers are a MUCH more fleshed out part of Pathfinder than their equivalents were in 3.X.

The list is here: https://www.d20pfsrd.com/gamemastering/combat/


I recommend that all players become familiar with these- even Lucien, because he will sometimes control a martial NPC. Much like 3.X, when you want to be good at something, you find the "Improved" version of it, but even without the "Improved" version, you will find use for these moves more often than you expect.

Specifically, note the rules about: succeeding always versus helpless opponents (you can reposition or drag a magically slept opponent, without waking them), getting a +4 versus a stunned opponent, the existence of the "steal" combat maneuver (generally a shit maneuver, but hey, you never know), and the universal rules for attacks of opportunity (a combat maneuver provokes in all cases by default, and a successful attack applies a penalty to the attack roll equal to the damage dealtt- so if you go to grapple a wizard, and he hits you for 6 in response, you may be just fine for actually rolling the grapple, even without anything being "Improved").

Combat Maneuvers that ANYONE can do (the entire list), include:
Bull Rush (move enemies in front of you)
Dirty Trick (improvise a minor debuff, be creative!)
Disarm
Drag
Grapple
Overrun
Reposition
Steal
Sunder
Trip
