By using three enchanted pieces of apparel combined with 100 alchemy, I created poison of damage stamina regeneration (decrease target's stamina regeneration by 100% for 100 seconds, causes 100 points of poison damage, plus causes 40 points of concentrated poison damage) worth 1097. Ingredients were: skeever tail + silverside perch + river betty. I'm saving them to use on a dragon.

Have you not used the jarrin root, don't use it for the quest, use it for alchemy and it grants a huge damage health effect. I made a damage health 25000 poison, which I used one hit on gallus and the other hit is saved on an iron dagger.

I used the fortify restoration loop a bit and had a poison that dealt something like "430 damage, 40 damage per second for whatever". I am not sure about the exact stats of this poison. Anyway, I felt that I was abusing the glitch too much at this point and stopped proceeding further along that line.

Jarrin Root+Crimson Nirnroot+Nirnroot=Supermegaultracyanide

FTFY

Potion of Fortify Health Weight 0.5 Value 1360

Health is increased by 36 points for 300 seconds. Drains the target's Magicka regeneration by 100% for 45 seconds. Conjuration spells last 45% longer for 66 seconds. Drains the target's stamina by 27 points.


I had to log into Skyrim and check my potion cabinat out to see.

No i use basic Nirnroot as the 3rd ingredient

Try crimson nirnroot when you get a chance. You will get even stronger poison effect.

Has both positive and negative effects.

I like Human Flesh+Imp Stool+Slaughterfish Scales. Damage health, plus lingering damage health, plus paralysis.

A bit of Vodka in a half glass of rum. Sorry that was the other night... My bad.
