how many spirtual weapons can you summon?

[Sgt Spectre]

like the subject states, someone said you could effectively create multiple, casting one each round

any clarification.

[mplindustries]

You can create as many as you have spell slots, if you really want to. Why would you think you were limited?

[Sgt Spectre]

so you can effectively have as many out as you have spell slots at once?

so you could theoretically have 5 out attacking on the same turn?

[Weirdo]

Yes, but you have to spend 5 rounds casting to summon them all, and since the duration is only 1 round/level you're unlikely to have them all in place before combat. By the time you get all 5 out, combat might be close to over. By the time you have enough resources to cast 5 2nd level spells, you've probably got something more effective to do with your actions and spell slots.

Might be cool if you've got a few rounds to summon them before you kick in a door.

Somewhere between a bit and a lot off topic, but if you really want to find a use for casting as many Spiritual Weapons as possible then go: Cleric/Magus/Mystic Theurge. You'd be using lots of spell slots, but you could get in ungodly amounts of weapon attacks per round.

Way off topic, I went and worked it out and Cleric 3/Magus 6/Mystic Theurge 3 is the first real sweet spot to optimize this "strategy". You prepare Spiritual weapon in all of your level 2 Cleric spell slots and all of your level 3 Magus spell slots. Then, if you Spell Combat, casting Spiritual Weapon every round you tip into the possibility of a staggering 90 attacks over 11 rounds with a peak of 13 attacks possible in one round. Are there other ways to do more damage and faster at a level 12? Yeah probably. Would the possibility of needing to do something other than a full attack arise and cut into that 90 attacks? Yeah, most likely. But gosh was it fun to think about.

I have a character that is super fun to play

They have magical lineage spiritual ally, and wayang spellhunter spiritual weapon
I have them keyed to toppling metamagic feat. So for each attack they get a chance to trip. With my high level paladin, that is a lot of trip attacks
Plus i usually start out with a quickened spiritual weapon and ally round one.
