Weird. I 've rarely used this spell but always assumed that it simply passed the damage to the caster, without any further fiddling.If it means the protected person becomes a new source of damage, then what would happen if the caster -- for instance -- had the "armour of agathys" condition. Would they damage the one protected by the spell for cold damage which would then turn back on themselves also ?
Nothing would happen with Armour of Agathys, since it specifies a "Melee" attack. While Warding Bond is considered a Spell.
But something like say, Cindermoth Cloak will trigger and yes, you can set your bonded target on fire, dealing damage, which goes back to the caster... Which triggers Cindermoth Cloak...
It's a pretty odd interaction to say the least.
