Shared property runes and Spell Storing.

[Falgaia]

Some questions I thought might be good to clarify early.

...Your eidolon benefits from the potency, striking, and property runes on your handwraps of mighty blows, and you can Invest a single magic weapon to share the benefits of those runes from the weapon as well, even though you normally can’t Invest a magic weapon.

1. If you're holding a weapon with the Spell Storing property rune, does this mean your eidolon now has 2 spell storing weapons equipped at all times? And if so, would a player be able to cast a spell into both, or would they share the Spell Storing rune between them and either attack hitting could proc the Spell Release?

2. Follow up question as it will come up with this build:

Spell Storing wrote:

...Activate: Single Action - Command; Requirements: On your previous action this turn, you hit and damaged a creature with this weapon...

Since Spell Storing takes a single action to activate, would it be useable through Act Together, or would being nested within Act Together cause Act Together to become "your previous action on this turn," despite still being in the process of carrying it out?

Presumeably any stored spells to be dropped during daily preparations due to the Invest requirement, but seems like it'd be a great way to make use of the summoner's limited spell slots that is definitely in no way stepping on any other playtest classes that currently exist. Assuming, of course, you are able to find a Spell Storing Weapon, since they are Uncommon and people like me are probably the reason Paizo staff made that decision in the first place. (I'm sorry.)

yes this account does have a post history debating that AoMF from PF1E should either stack Furyborn for all Natural Attacks if any Natural Attack hit, or it should let you store a spell in each of your Natural Weapons if you ran Spell Storing as one ruling implied it gave the property to each weapon individually and the other implied the weapons were somehow connected by the amulet as one unit; what gave it away?
