Buy a summoning spell (Demora and Demora Lords are best) and a soul trap spell (NOTE: Make sure you select to buy SPELLS, NOT SCROLLS!!!). After you get both "soul trap" and summoning, talk to someone with the "spellmaking" option at the top of their options list. First put the summoning spell in for five seconds and below that put "soul trap" in for TWO SECONDS ON TARGET. Finally, give the spell a cool name. For instance, if you are summoning a Hunger, name the spell "Eternal Hunger".

Now that you have a spell that has the potential to summon any creature permanently, you've gotta know how to cast it correctly. First, go to any place you can legally rest without using a bed. Equip the spell and look STRAIGHT DOWN. Now cast it as many times as possible, rest, repeat as many times as desired. Soon enough you will have an army that will defend you from anything that disturbs you while you are resting or harms you.

Enjoy,
