It has come to my attention that the text of Warding Bond, the legal target(s) of Warding Bond, and the rules as written for target's and spell casting and such; leave it possible that Warding Bond can be cast on multiple targets; each casting of the spell targeting a new willing creature; so long as you are able to provide the material components to each creature.
PHB pg 287.
1 Action
Range of Touch
Components: A pair of Platinum Rings which you and the target must wear for the duration.
This spell wards a willing creature you touch and creates a mystic connection between you and the target….
The spell ends if …. the spell is cast again on either of the connected creatures …
So we know Warding Bond only targets one creature, as emphasized by me above, the creature that you touch and thus designate as the singular target of the spell. The spell doesn't have a target of 'Self' , nor does the spell have the ability to target more than the designated touched creature when you cast it. The spell also lasts for a full hour of non concentration.
So it occurs to me that, if I have several complete sets of Platinum Rings, let us say 3, and I am wearing 3 of them on separate fingers and give each matching ring to 3 of my companions; I can cast this spell 3 times on each of them, never once targeting anyone already affected by the spell and never once being affected by someone else casting the spell. I would then be sharing 1/2 damage from 3 separate sources for about 1 hour.
Nothing I have found prevents this except for A: I cast the spell again on one of the already affected companions. B: Someone ELSE casts the same spell on one of the already affected companions OR on me, effectively ending the spell.
Does anything, RAW, prevent me from having multiple instances of Warding Bond active as long as a different creature has been targeted for each separate instance?
