Note: Obscuro's Oblivion Overhaul (OOO) or one of the other mods that I have installed plays with ingredient weights. So the un-modified version of Oblivion will result in higher potion weights. Note that the first potion of a particular name and strength sets the weight for all other potions created under that particular name and strength. So use the lightest weight ingredients first (make a single potion) then use heavier ingredients until you see the potion effects change (when your Alchemy skill increases).

Any listed effects were calculated at Alchemy level 83 (with Luck of 85). I try not to list any rare or hard to obtain ingredients in my lists. I'm using Expert level Alchemy equipment (except for a Master level Retort)

Poison (Caster, Fire) (0.075 best weight)
- Combine Harrada (0.1), Spiddal Stick (0.1), Steel-Blue Entoloma Cap (0.1) and Bergamot Seeds (0.0)
- Damage Health: 7 pts for 28 sec, Damage Magicka 13 pts for 52 sec, Fire Damage: 8 pts for 34 sec, Silence for 23 sec
- A nice lightweight potion that can be used to great effect against casters.

Poison (Caster, Frost)
- Combine Black Tar (0.1), Harrada (0.1),

Poison (Caster, Shock) (0.1 weight)
- Combine Black Tar (0.1), Harrada (0.1), Ectoplasm (0.1), and Rot Scale (0.1)
- Damage Health: 7 pts for 28 sec, Shock Damage: 8 pts for 33 sec, Silence: 24 sec, Paralyze: 3 sec
- Although it's a small pain to obtain the ingredients, it's useful in cases where you want to knock down (paralyze) an opponent.
