Sand Vipers are effected by the Slow Death sphere while using the Split Vipers sphere. This leads to a decrease of it's damage. As soon as the player uses the Split Vipers Sphere the Slow Death Sphere should not work on Sand Vipers.
Steps to reproduce:
It should be only possible to equip either of these 2 spheres for both together are useless, or the Slow Death sphere does not work as soon as the Split Vipers sphere is placed inside a sphere slot (this is doable, bugs can do it already too with other spheres XD).
