The warding bond spell description states:
While the target is within 60 feet of you, it gains a +1 bonus to AC and saving throws, and it has resistance to all damage. Also, each time it takes damage, you take the same amount of damage.
If you cast the spell on another creature and then that creature is damaged, what type is the damage you take? If the target receives 12 slashing damage, do you get 6 slashing damage, or just 6 (untyped) damage?
