Full Channeling as a Hospitaler Paladin

[KiyoshiKirin]

DM here, wondering what the best options for a player when it comes to scaling up channeling with their level. Player is a Hospitaler Paladin, which has the following ability:

Quote:

Channel Positive Energy (Su)

When a hospitaler reaches 4th level, she gains the ability to channel positive energy as a cleric equal to her paladin level –3. She can use this ability a number of times per day equal to 3 + her Charisma modifier. Using this ability does not expend uses of lay on hands, as it does with other paladins.

This ability replaces the standard paladin’s channel positive energy ability.

Seeing as how feats like Boon Companion allow you to effectively scale up your level for the Animal Companion feature, is there a feat or special ability that will let them scale up their channeling ability, or would I need to homebrew something?

Other than a Phylactery of Positive Channeling, you'd have to wing something.

[Chess Pwn]

There's nothing that increases your level for channeling.
Phylactery of Positive Channeling will give you a 2d6 boost, which is like 3-4 levels, but you wouldn't be a full channeler still.

Well, there's Variant Multiclassing: Cavalier (Order of the Stars).

It doesn't come online until 7, but it actually gives you *better* than full channeling - at the cost of half your feats.
