The BG3 Warding Bond also doesn't end if the caster drops to 0 HP (It's such a hassle to get a downed WB caster back on their feet.) and most players seem to use it with a camp follower or a companion they leave behind so the 60 ft rule also does not seem to apply.
In reality, the actual quirk of this spell is that the damage to the caster is counted as if it came from the Bonded target. So if the Bonded target has effects like the Caustic Band, Callous Glow Ring, Elemental Adept etc. These effects are applied to the damage that gets sent to the caster. Which is more of a Larian coding quirk than a RAI scenario.
Thank you, I hadn't even considered this. ^^;
