Eidolon and Ghost Touch.

[Delenot]

Trying to ready myself to fight incorporeal creatures and I have a few questions.

I currently have an Amulet of Mighty Fists +1. This makes all natural attacks from the Eidolon +1 magic. Attacking an Incorporeal creature with these natural attacks should work at 50% damage, correct?

The evolution...Shadow Form (Su)*

Source: PRG:ARG

The eidolon's body becomes shadowy and more indistinct. This shadow form grants the eidolon constant concealment (20% miss chance), and its melee attacks affect incorporeal creatures as if it had the ghost touch weapon property. The eidolon's melee attacks deal only half damage to corporeal creatures.

This looks like it functions exactly like the amulet does for damage purposes, correct?

Also, Shadow Form states that the Eidolon's melee attacks deal 50% damage. Does this only apply to weapon attacks, or to natural attacks too?

Is there any method to gain full attack damage against Incorporeal creatures from the Eidolon?

You could always teach it how to swing a ghost-touch weapon around. Martial Weapon Training is an evolution, I think, and it shouldn't be too hard to find an sharp stick with an enchantment on it

[EvilMinion]

You already found one. With shadow form, the melee attacks do 50% to corporeal creatures, not incorporeal. You get full damage on incorporeal.

Did I really miss that? Yerp! I really missed that! Well, it's not the first time I feel simple, sure ain't gonna be the last! Thank you!

[Delenot]

Does the % miss chance from Incorporeal, and the evolutions Shadow Form and Shadow Blend, apply to other Incorporeal combatants?

[EvilMinion]

There is no miss chance due to being incorporeal.

The concealment from the evolution should apply to everything (corporeal or not). that's part of the 'shadow' stuff, not the 'incorporeal' stuff.

Shadow Form is not making your eidolon incorporeal. Be clear on that. It gives it some concealment, and allows it to affect incorporeal creatures... but it is not incorporeal itself else it would not need to give it the Ghost Touch ability, as incorporeal creatures can already affect other incorporeal creatures.

And just for clarity, you can give your eidolon the shadow form evolution via the level 2 summoner spell, lesser evolution surge.
In case you don't want your eidolon all shadow all the time.

Also, this evolution might not be PFS legal, unless you're a Fetchling... if it matters.

[Delenot]

Yes, I'm looking to use the Evolution Surge spells to do this because I do not want it in that form permanently. This is exactly what I'm looking for, provided of course I read it correctly from the get go! Thank you again.
