Couple of summoner questions

[habibo]

Hello i tried searching for these answers but all the topics seemed to answer questions about multiple attacks or were never answered

So i gave my eidolon limbs and it's azata so it can wield weapons

it has a darkwood shield so ac but no attack penalty even w/o proficiency and a great sword but if i make the sword magic can my summoner then not have a magic sword w/ overriding the eidolon's because of the link? obviously the shield isn't an issue because i wont be using one due to spell failure chance

and i couldn't find an answer to if you add reach to the claws if it gives you reach with the weapon

Since you're referring to its Azata nature, I will assume you are talking about an Unchained Summoner and not the original class. Is that accurate?

Link simply says that the summoner and his eidolon share slots and can't both benefit from magic items in the same slot. Since wielded weapons are not a slot, I'm pretty sure you're fine with both individuals using magic weapons at the same time.

The Reach evolution applies to only one type of attack. If you give it to claws, it won't apply to wielded weapons. If you're trying to accomplish reach with a wielded weapon, I would recommend the 4-point evolution Large. In addition to the other effects of being large, your eidolon gains reach with all attack types if it's a biped.

you only have to worry about slotted items. If the item is slotless, your good.

Yes, I remember that my summoner and his eidolon used to really love Ioun Stones for that reason.
