Girallon's blessing + rogue

[Thanos92]

Hello, rapid question.

Let's say I'm a Human rogue 5 with TWF and 2 daggers. I normally and basically fight with +3BAB -2 TWF penalty = +1/+1.

Then the cleric casts on me Girallon's blessing (using SC version, not SS) and I use my 2 brand new hands to take 2 new daggers. Now I'm fighting with 4 daggers. Which bonus will I use?
Technically the spell says that his first arms are considered his primary limbs and the new one his second, but in this case we are not talking about natural attack so Multiattack shouldn't be considered, right?

Will it be +1/+1/+1/+1? (which means 2*4 = 8d6 of SA at level 5)

Thanks a lot

You would use the multiweapon fighting rules, so not the two weapon fighting rules, so a -6 penalty for your primary hand and -10 for all secondary weapons.

Ask your DM about the "This feat replaces the Two-Weapon Fighting feat for creatures with more than two arms" to see if the feat upgrades for the duration of the effect granting multiple arms.

If so, if it upgrades, than it would be +1/+1/+1/+1 right?

No, it would be -1/-1/-1/-1 (http://www.dandwiki.com/wiki/SRD:Multiweapon_Fighting)

Oh right, my bad.

There's one improvement PF2e could make: cleaning up things like that ambiguity. Have Multi-Weapon Fighting be the only feat, and allow creatures with any number of limbs to take it. It handles TWF and the more-armed equivalents.
