---Introduction---
=============

Once again, I decided to reinstall Oblivion, as well as to update this mod for my personal use. However, I decided to share it on nexus in case you want to use it too.

Version 4 comes with few changes, if you are already using this mod you can skip the Description section and go straight to the Changes section. 

============
---Description---
============

This is a simple mod that adds 3 altars in Cyrodiil and 1 in Shivering Isles that you can use to convert any soul gem to Black soul gem. It works exactly as original altars, except the fact that, with this mod, you can use them anytime you want and there aren't those 'purple effects'. You know the procedure, insert an empty soul gem in the altar, cast soul trap on it and take your prize. In order to avoid this being a cheat mod, the weaker the soul gem is, the more of them you need to swap for one black soul gem. So, this is how it works:

- You need 5 empty Petty SGs to swap for one Black SG;
- You need 4 empty Lesser SGs to swap for one Black SG;
- You need 3 empty Common SGs to swap for one Black SG;
- You need 2 empty Greater SGs to swap for one Black SG;
- And of course, you need 1 empty Grand SG to swap for one Black SG.

Say that you place 3 common, 1 grand and 5 petty soul gems in altar and cast Soul Trap once. You've just made 3 black soul gems.
I don't consider this as cheat mod, because Bethesda should have made BSGs more common.

===========
---Changes---
===========

1. Unlike in previous versions, all you have to do is cast the Soul Trap on the Altar once and no matter how many Soul Gems there is in altar they will all be converted as long as they are convertible (if you have 7 Greater Soul Gems, you will get 3 BSGs immediately, and 1 Greater Soul Gem will remain). 

2. Now there are only 4 altars in the world because it always bothered me that I've put the altars in Mages Guild when necromancy is banned, you had the altar in Anvil which simply doesn't make sense having in mind that Carahil is strongly against it. There is only one MG location where it made sense to put the altar in. 

3. Fixed the duplication issue, the script should now work as intended, but please let me know if something unexpected happens.

---History---
==========

v4:
 - changed locations again
 - fixed duplication bug
 - casting soul trap once should be enough to convert all the soul gems

v3:
 - changed locations of altars as suggested years ago;
 - smaller altars to avoid incompatibility with other mods;
 - now includes only one .esp, to avoid Data folder clutter.

You can do whatever you want with this mod as long as it's not used for profit, and you credit me.
