Restore Health, Restore Fatigue, Cure Common Disease:
Saltrice, Wickwheat, Chokeweed, Muck
(ingredient cost 4)
Restore Magicka:
Comberry, Frost Salts
(ingredient cost 77)
Restore Health, Cure Blight Disease, Fortify Willpower:
Saltric, Wickwheat, Ash Salts, Scrib Jelly
(ingredient cost 37)
Thanks (!) to your suggestion I use these three, plus three that I have created. All ingredients can still be found in Balmora.
Restore Health, Lightning Shield, Cure Paralyzation, Restore Fatigue:
Corkbulb Root, Saltrice, Crab Meat, Willow Anther
NOTES: My first 4-effect potion! But unlike the others above, weighs 0.2.
Restore Health, Cure Poison, Fortify Willpower
Marshmerrow, Scrib Jelly, Black Lichen, Wickwheat
NOTES: Among the four "restore health" potions I carry I can cure blight disease, common disease, paralization, and poison. Just about anything, I would guess.
Restore Magicka, Fire Shield, Frost Shield
Comberry, Frost Salts, Fire Salts, Willow Anther
NOTES: This is an expensive potion. I may choose to make some with fire and some with frost, but not both. But fire/frost/lightning shield effect also does *damage* to those who are near the shield. Thus, drinking potions to get all three effects rolling during a fight where you are being crowded -- just by standing there you will be doing decent damage.
I am not using any tricks to create more powerful potions. But still I am finding that if you are drinking lots of restore health potions you can be rather difficult to kill.
Once you have maxed Alchemy skill and obtained Grandmaster equipment, if you do no fortifying prior to making potions then all your potions are identical. All of your potions then "stack" in your inventory, keeping the inventory menu very clean.
