Question about arcane weapon enhancements

[the jon mustaert]

Arcane weapon (x) reads .."consumes 1 point of enhancement bonus"
does this primarily mean that when toggled, it is similar to arcane accuracy/arcane weapon enhancement?

Assuming I already have keen on a fauschard, does it mean that I can't use them?

It is similar to the paladin divine weapon bond, you pay with the +1 to +5 arcane weapon enhancements to apply buffs on your weapon or just increase his enhancement bonus.

For example, my level 17 magus(+5 arcane weapon) has a simple +4 fauchard. I use arcane weapon and buff that +4 fauchard with >>>

- holy (cost +2 enhancement from arcane weapon)
- shock (cost 1)
- keen (cost 1)
- +1 arcane weapon left = +1 enhancement to the weapon

Now my fauchard is a +5 keen, shock and holy for 1min or 1min/level with enduring blade.

Note class level determines enchantment point budget - activating Arcane Weapon costs 1 Arcane Point from your AP Pool (+1 with Enduring Blade, +1-2 with Bane Blade). And for that you get an Enchantment budget.
By default, it reinforces the enchantment level of your weapon (capped at +5). But instead, you can spend this "bonus enchantment" budget on other weapon powers, such as Keen, Fire/Ice/Shock (for +1 each), Speed (for +3), Ghost Touch (for +1), Devoted Blade (for +2), Brilliant Energy (for +4).
Additionally you can add Bane Blade on top.

Many of these powers require selecting appropriate Arcana first.

Does Devoted Blade stack with Bane Blade?

Yes!
