Warforged: Slam attacks and unarmed strike

[Nightmarenny]

Note:My question is concerning a player of mine's Character. He has been very explicit regarding what he wants to use for his character. So any response ala "Just play Swordsage" would be unhelpful.

In a campaign I'm DMing a player of mine has choosen to play an Unarmed Fighter Warforged. I am not sure how his attacks would work and neither is he. I think it would work like this(he took Improved Unarmed Strike and TWF btw)

level one:
slam Attack(at max attack -2)
main hand Attack(at max attack -4)
off hand Attack(at max attack -4)

Level Six

slam Attack(at max attack -2)
main hand Attack(at max attack -4)
off hand Attack(at max attack -4)
Second main hand Attack(at max attack -9)

Is this correct?

No, the unarmed strike is always the primary attack, with any natural attacks secondary/offhand strikes. You can rule otherwise as in fact there is a WOTC web page that does.

Assuming full attack

unarmed strike (max-2 for two weapon fighting and then iteratives if you have them) second main hand would be at max-7
unarmed strike (max-2 for two weapon fighting and this is your "off hand")
slam (max -7 for secondary weapon and two weapon fighting penalty)

Ok so let me try this with real numbers. Lets say he has a 18 strength and no other feats that would effect attack.

level one Fighter +3 Unarmed Attack, +3 Offhand unarmed Attack, -4 Slam

Level Six Fighter +8/+3 Unarmed Attack, +8 Offhand, +1 slam

Level Eleven Fighter +13/+8/+3 Unarmed Attack, +13 Offhand, +6 slam

Correct?

Level Eleven Fighter +13/+8/+3 Unarmed Attack, +13 Offhand, +6 slam

Correct?

Level 1 Fighter with 18 Str and TWF as a feat is:
+3 UA/+3 UA/-2 Slam

The same, you've applied an extra -2 to all of those Slam-attacks. When used in lieu of your other attacks it's your primary attack bonus -5; the same as your first iterative.

Alright thanks.
