Imp Stool · The Elder Scrolls V: Skyrim: Alchemy effects and matching

Using this reference

Look at the effect list for Imp Stool before comparing weight or value. In the comparison tool, a shared effect means that both recorded ingredients list it. An empty match means this pair has no shared effect in the reference, not that either ingredient is useless.

Try a second ingredient with a different overlap to see which combinations preserve the effect you want. The checker is a pair lookup; it does not calculate potion strength, sale value or the outcome of a third ingredient. Keep those questions separate when deciding what to carry.
