This will be a tldr thing if you're not into paladins, but here's a concept I've been batting around with Leafi and Nehor. Please feedback.

There are paths that distinguish a paladin from another. Some fight for glory, some for honor, some out of hatred. The Paladin's patron determines what paths they have available to them. Each chosen path has with it a basic, epic, and legendary passive skill that can be trained that personifies the path itself. If the Paladin's patron is of Liabo, they may train in the Liabo and Neutral paths. If the patron is Lornon, they may train in the Lornon and Neutral paths. However, patrons that are of neutral influence only grant access to one or the other at the paladins discretion - Neutral/Liabo, or Neutral/Lornon. Once this choice has been made (by spending ATP in a Liabo or Lornon path), it may not be changed except through intercession (as would a Liabo paladin who converted to Lornon be required to switch to Lornon paths). All previously unlocked paths are still unlocked, however they cease to function while not of the paladin's chosen alignment.
Auras are abilities that are granted the paladin upon training in the basic and epic levels of each path (the legendary unlock does not provide an aura). Paladins may only have one aura active at a time, and it must be unlocked and of an active path. A paladin may change their aura by activating another aura, thus ending the previous, or by using a STOP AURA type command. They may do this once per minute to prevent abuse.
The neutral paths are those that either lornon, liabo, or neutral paladins have access to. Their auras are therefore also always available once unlocked:

1. Path of the Crusader: The paladin has the eyes of their patron guiding them on their quests as they crusade in his or her name. Intervention path.
a. Basic Unlock - "Campaign": 1618 becomes a stackable spell with duration of 1200 + 60/spell level over 18. Granted access to Aura of Vigilance.

2. Path of the Duelist: The paladin fights with tenacity, and is the king of attrition combat. 1v1 melee path.
a. Basic Unlock - "Eyes on Me"; Every connected melee attack has a chance to proc single target 1608 against the foe. Granted access to Aura of Challenge.
b. Epic - "Always a Fair Fight"; The paladin is immune to FoF pushdown. Granted access to Aura of Healing.
c. Legendary - "Opportunist"; Double the bonus and penalty of Zealot.

3. Path of the Armed: A paladin's weapon is a gift from their patron, and those especially devout can make the most of it. Weapon Sanctification Path.
a. Basic Unlock - "Sanctified Arsenal"; A paladin may bond via 1625 to two different weapons. Granted access to Aura of Blades.
