Effect Shader "Priority"

[guerillamoderno]

Do any of you guys know if there's a way to make certain effect shaders display over other ones? For example, the Ebony Mail's "DA02ArmorShadow" effect shader appears to be overridden by almost all other "cloak" type spells. I'm making a mod that makes an item that gives this visual effect all the time, not just when sneaking or in combat (and without the poison damage enchantment) and would like to have it "outprioritize" other effect shaders.

Here are some images to demonstrate what I'm talking about:

This is the shadowcloak effect when it's the only effect present:

This is what it looks like with oakflesh active as well. The green mage armor effect overrides the black effect, and the only thing remaining from the shadowcloak is a few blackish-green wisps of smoke radiating around the player:

This is with a flame cloak spell, oakflesh, and shadowcloak. Flame cloak appears to have the highest priority, completely overriding oakflesh. Once again, shadowcloak is relegated to a few wisps of smoke:

I'm looking through the SpecialEffect > EffectShader section of the Creation Kit at all these spells' entries, and it's a whole ton of really alien-sounding descriptors with numeric values, and frankly I don't know where to begin, or even if making changes to any of these values will actually produce a change in priority and make the shadowcloak appear over other effects. If anyone has experience with this kind of stuff I'd greatly appreciate your input.
