So today is the first time I have ever tried to enchant something other than a sigil stone. My question is how can I put more than one effect per item or if there is even a way. Only asking because on most of the magic loot from quests and whatnot there is more than one enchantment on it

http://www.uesp.net/wiki/Oblivion:Enchanting#Enchanting_using_Altars is what the UESP Wiki has to say about it.

Enchantments?... Enchantments!

Gotta love Sandal.

Weapons may be enchanted with multiple effects. Armor and jewellery may not, at least not without mods.
