If you use this recipe so NOT upgrade purify as it reduces the effects Wouldn't that be a self damaging potion then? not a poison because of invisibility? Not exactly. It's possible to create poisons with benefical effects, just as it's possible to create potions with detrimental effects.

However, the Crimson Nirnroot/Regular Nirnroot combo is not the most powerful combo. Use a Human Heart and Blistwort instead. I'm unaware of the Alchemy skill or perks, as this is listed on the Wiki page for Jarrin root, but with those ingrediants, you can potentially reach 6480 points of poison damage, more than double the Nirnroot one, and has 4 additional effects (assuming anything can survive 6,000+ damage) as opposed to the 3 of the Nirnroot one.

I've noticed using Nirnroot in poisons weakens the poison. Not sure why.
