Can I get a wand of Ki arrow, cast it on 50 single arrows and have those arrows last until I use them? Duration is instantaneous but I wasnt sure if I had to throw them immediately or if I could have a bundle waiting until needed.
You imbue an arrow with your power and throw it at a target up to 100 feet away. Make a ranged attack roll. If it hits, the target takes damage from the arrow as if you had hit it with a single unarmed strike (including your Strength bonus)
The attack is part of the spell, that is why it is instantaneous.
So you would use the wand and immediately attack with the arrow, no duration required. Just like you would cast Ray of Frost and immediately attack with it.
