Use immolation, and change the art into monsoon rain. Then edit the buffs so they look different, and finally, add a temp negative brilliance aura when activated.
Or use a fan of knives ability which, when used, gives a temp ability based on permanent immolation with monsoon rain art for a limited time, as well as the negative brilliance aura. You can set a trigger so that the level of the Permanent Immolation based ability's level is the same as the level of the ability.
