Warrior Spirit "maximum bonus"

[Zesty Mordant]

Most of my questions about Warrior Spirit were answered in this awesome thread: http://paizo.com/threads/rzs2urzb?Armed-Bravery-or-Warrior-Spirit#1

However, rather than necro that thread I'll ask here, where it say "his maximum bonus" what bonus is it referring to? I'm assuming it means the Weapon Training Bonus 'maximized', but is that with or without the +1 added to it? Or am I completely off base and it's a different bonus?

Quote:

Warrior Spirit (Su) The fighter can forge a spiritual bond with a weapon that belongs to the associated weapon group, allowing him to unlock the weapon’s potential. Each day, he designates one such weapon and gains a number of points of spiritual energy equal to 1 + his weapon training bonus. While wielding this weapon, he can spend 1 point of spiritual energy to grant the weapon an enhancement bonus equal to his weapon training bonus. Enhancement bonuses gained by this advanced weapon training option stack with those of the weapon, to a maximum of +5. The fighter can also imbue the weapon with any one weapon special ability with an equivalent enhancement bonus less than or equal to his maximum bonus by reducing the granted enhancement bonus by the amount of the equivalent enhancement bonus. The item must have an enhancement bonus of at least +1 (from the item itself or from warrior spirit) to gain a weapon special ability. In either case, these bonuses last for 1 minute.

His maximum bonus is the weapon enhancement bonus equal to his weapon training bonus:

For example, a 9th level Fighter gains a +2 bonus from Weapon Training, so you could grant +2 worth of additional enhancement bonus to his weapon: either +2, +1 and a +1 equivalent enchantment, or a +2 equivalent enchantment assuming the weapon in question is already magical (i.e., has a +1 Enhancement bonus).

Equipping duelist gloves would increase this bonus to +4, etc.

If your bonus is 5 and you have a MW weapon, then you can have any of these:

• +5
  
• +1 brilliant energy
  
• +2 nullifying
  
• +3 holy
  
• +3 flaming

er, make that last one +4 flaming. Oops.

I think it is basically referring to how you can have multiple weapon training. You pick one at level 5 then one at 9, 13, 17 ect. So if you took it for your 2nd weapon training group you could still use it to get a +2 (Example at level 9 you have +2 in large blades and +1 in close you take this to make the close more versatile and can still add a +2 weapon enchantment to them.)
