Eidolon + Monks Robe + Improve US

[Lumbross]

Hi. My question is the next.

I`m making an eidolon with 4 arms (2 limbs evolution) and a BAB of +9, and i want it to attack with all his 4 bare fist.

Do i need the feat Improve Unarmed Strike to make those attacks lethal?
If i equip him with a Monk`s Robe, will his fist make 1d8 of damage?
Do i need the feats Two-Weapon Fighting and Improve Two-Weapon Fighting to make more than 2 attacks?

If he has a STR of 28 how will be the result to his attacks?

Note, that all i want is cosmetic, not for PG.

[Chess Pwn]

yes, IUS is required to do lethal unarmed strikes.
yes monk robes makes your IUS do 1d8.
No, you can TWF without any feats for major penalties.
If you want to make more than 1 attack you need to TWF though, and then you're also only fighting with 2 arms and getting half strength on your off hand.

Technically I am pretty sure the feat you want for a 4 armed eidolon is multi-weapon fighting. There are some pretty lengthy threads about multi-weapon fighting though and how it actually works.

If you aren't doing it for power gain work it out with your GM. If you trying to do it in PFS expect significant table variation (and multi-weapon fighting isn't allowed) so you wont be swinging all 4 unarmed fists there anyhow.

For example.

This Eidolon with:
The evolution Limbs x2 and claws x1
BAB+9 and STR 28
Feats: Improved Unarmed Strike, Weapon Focus (US), TWF, Improved TWF, Multiattack (eidolon bonus)
Equiped with Monk`s Robe

His Full Round Attack using the arms without claws as bares fists and also attacking with arms with claws will be:
Unarmed Strike primary hand +17 / +12 (1d8+9)
Unarmed Strike off-hand +17 / +12 (1d8+4)
Claws x2 +17 / +17 (1d4+9)

am i correct?

No. When you combine natural attacks with non-natural attacks the natural attacks all become secondary.

[Lumbross]

I get it. Secundary natural attack have a penaltie of -5 to attack roll and use onlie 1/2 strenght to damage.

But the feat Multiattack reduce the -5 to -2

So claws attack will be with +16/+16 (1d4+4)
