I love Alchemy. In fact my user name and avatar is based on alchemy . Alchemy in every context I am all over it. I collect all the alchemy books in game too. Think about it also, alchemy is the most powerful skill in Morrowind and Skyrim with the exploit.
The last time I played Morrowind was on my Xbox until I crashed the game because I had made potions that were restoring health for a total of 16,000 points over 200 some minutes, fortifying health, stamina, magicka, strength and agility by a few hundred points each, much moreso for the health and the stamina.
I went through Morrowind, cackling like a madman as I crushed anything and everything that got in my way. I struck down a god in a few blows while his were received like a punch from a gnat. I was naked, carrying a daedric daikatana and he couldn't even damage enough to leave a hint of an impression on health. I struck down Dagoth Ur on the first shot.
Then I went to some fishing village that had a problem with breeding...netch? Whatever big floating gas bags there were that were breeding there. Saved, game crashes after. Every time I load up the save, it gets as far as the screen and the background water sounds.
Alchemy in Morrowind was ridiculous, and that was pretty awesome.
The trickiest alchemical ingredient to harvest has to be hawk feathers and beaks. I've heard you can kill the hawks, but I've never had any luck with it. I svck at archery and my fire breath shout doesn't seem to work on them.
I managed a shot with an arrow on one, once in Solitude. It landed outside the walls. 5 minutes of chasing the bastard, just for curiosity, and that's what I got for it.
