I do not normally ask questions that are not direct. A question generates a very particular answer set. In this I am unsure how to present the question so that is not seen as speculative or opinionated. I know those sorts of questions generally do not share a long life span compared to the normal ones we ask around here. Any suggestions on the matter are appreciated and will edit this out once established.

This question is a follow up of This Question concerning casting Warding Bond on multiple allies. It was found that This Tweet confirmed my suspicions that it is possible, given a separate pair of rings for each separate creature I want to effect when I cast Warding Bond, to share damage with multiple allies.

Now that we know this is possible, I am curious as to the nature of the survivability of my level 5 Hill Dwarf War Cleric using the Tough feat and taking the average HP every level up for a current total of 53 HP.

It is safe to assume the more simultaneous bonds I have active at any given moment, the lower my survival rate becomes. Sharing 1/2 damage from multiple sources is bound to be hazardous since there is no way to reduce that damage even farther. So how thin can I spread myself without being suicidal?
