Certain Feat and Eidolon

[Shinto13]

SO I am playing a Summoner and I took the Improved Shared Spells feat. I just hit level 13 so I can get level 5 spells. One of the spells I chose was WREATH OF BLADES. With that feat and that spell, how many daggers do I need and does it affect both the Eidolon and myself or just myself or just my Eidolon since it is a target of "you" which means i can cast on him?

There is nothing in the feat that says you need additional components for spells that require them, so you would still only need the 4 daggers as per the spell. With Improved Spell Share you can have the spell effect both of you but at half duration or you can have it just effect just your eidolon for full duration as per the base Share Spell ability.
