Looking for a Dip or multi-class investment for a lore-warden Fighter

[Nosta1300]

I am Building a level 6 character here and could use some sujesstion for a Dip or Multi-class for a Human Lore-warden fighter.

The character is going to spinning a reach weapon around and I and considering going the trip route. But not 100% On that. I do know I want a polearm as my weapon

I few my character as a tactical fighter

Spear Dancing Style Feats seem obvious. I like the Lucerne Hammer. 1d12, Piercing, Bludgening, and Brace. Spear Dancing Feats let you apply Quarterstaff Feats to your Lucerne Hammer such as Tripping Staff, Quarterstaff Master, and Perfect Strike. Magi with the Tripping Staff Feat can apply Spellstrike on Trip Attempts, so maybe Magus is your dipping class?

The Tripping Feats are Combat Expertise (underrated!) or Dirty Fighting, Improved Trip, Vicious Stomp, Fury's Fall, and Greater Trip. Vicious Stomp gives you an additional Attack of Opportunity on top of what Greater Trip gives you, but it has to be an Unarmed AoO. If you dip a level in MOMS Monk, you can take 2 Style Feats, such as Ascetic Style and apply Unarmed Strike Feats to your Pole Arm. If you dip a level in Cavalier, you can get Paired Opportunist and give it to the whole party via Tactician. That way, whenever any of you gets an Attack of Opportunity (You get 2/round!), all of you get one! There is potential for some really scary synergy, here!

Occultist makes a decent dip for a fighter with a bit of Int. Alternatively there's wizard for dimensional shift...but if you're starting at level 6 you may want no dip, because a fighter can get a bonus feat then and a tripper really wants the greater trip feat (prereq BAB +6).

BTW a tripper with a reach weapon may want tangled limbs and titans tangle eventually. Probably after L6 though.
