All sources, no homebrew. Level 10-15. I really only need synergistic abilities, I am capable of building a character myself but cant find much information on mounted charging anywhere.
Post #2 under Charging.
That is awesome thanks, didn't turn up in my search because Kishi Charger isn't in the table but It looks like you aren't including classes anyway.
Nope, it's base classes (post 1) and themes (post 2).
You really want to go for broke. I think Kishi Charge adds a multiplier (x2 normal, x3 with a lance), Spirited Charge makes that x4, Riding Boots for x5, Valorous for x6. With Great Cleave you get extra one attack per kill and Lance of the Unending Charge greatly extends the range of your bonus movement (from 5ft to your mount's speed). And an intelligent mount with the Twisted Charge Skill Trick would even let you turn 90 degrees while charging too.
I can't say I know of other abilities that let you change directions while charging, but with enough of them you could dart around a city murdering EVERYONE on the streets on the same initial attack action. Fun times.
