When Dehaka devours a massive unit, the buff gained will shoot spines back at an enemy when Dehaka takes damage. With the Devouring One prestige, these effects are supposed to affect all units near Dehaka. Instead, when units that gained this buff are damaged, all of the spines that shoot back come from Dehaka. This is especially noticeable when armies split after a massive unit is devoured and spines come flying from halfway across the map.
