Twin Spell and Spiritual Weapon

[Foff]

We've been discussing this over in other threads, and it's looking like a no-go.

The spell doesn't target anything, and to twin a spell it must target a creature. Spi W summons the weapon and then you make an attack with it - so I guess it's not twinable.

I guess they didn't want Sorcs twinning summoning spells, if they got them somehow - through multi or a magic item maybe.

Also if you cast a second Spi W it erases the first one. So if you did twin it, unless they came into existence at the same time, the second one would "erase" the first one.

That's okay because you can twin dragon's breath, and it's a lot more fun. You cast it onto two party members - or you and another party member, or you and a familiar possibly! I mean it looks like it's RAW to be able to cast that on a familiar, though a very strict reading of familiar by a dm might mean the big "no" to that (fams can't have an attack action of any kind is quite possibly what the phb is saying). So okay, maybe not workable on a fam, but on two party members - or if your druid summons two dire wolves or something, cast dragon's breath on them - twinned! That'd be a hoot. Or on sprites or little silly woodland creatures... this is getting surreal.

I'd argue they're not taking an attack action, they're not even rolling to hit, idk
I'll keep casting dragon's breath on my handheld cat-thrower
and i'm not going to be overpowered by doing so
