You use them to enchant or recharge magical items.
Usually in random loot.
If im right, then i suggest you are talking about the game Elder Scrolls IV Oblivion. If so, Then no you can't.
petty soul gems, lesser soul gems, greater soul gems, grand soul gems
You can easily find the expensive and stronger soul gems by going to a mage guild become part of it and then you can search all the places for gems. if you want bigger go for getting all the recomendations and then go to the arcane university. there will most likely be very good gems and staffs you can take. i suggest that if you can go the deans dorm and if you can take his staff without stealing it then take that.
No. Soul Gems are used for enchanting and recharging magic items.
Assuming you mean Grand Soul Gems, they are usually on display or for sale in various Mages Guild halls, though the Chorrol hall is the best bet for taking them for free- if you can pick the locks on the display cases, that is. And once you get your level high enough, you can start to find them around dungeons- but only rarely.
Nope, you have to use filled soul gems on it.
Black Soul Gems are the only soul gems that can trap the soul of an NPC, including all ten playable races, and NPC daedra such as Dremora, and Shivering Isles' Aureals and Mazken.
it may be you're birth sign atronach=no magika regen NOT SOUL GEMS!
First you have to have a filled Soul Gem,Then go to an Enchanting Station like the ones in the Arcane univercity. you can also use a variety of game mods on the net to do much the same for much less cost.
Basically, Any sentient human being or dremora soul can be placed inside the gems, and will automatically equal to a Grand soul (highest level soul in the game)
