If soul gems work exactly the same way as in Oblivion. Do you think the Conjuration perk Soul Stealer will do more harm than good? More specifically, will you be really annoyed to have your grand soul gems used to capture souls of rabbits and deer.

Doesn't it fill up the lower ranked soul gems first?

I thought the Soul Stealer perk just recharged your current weapon, instead of being "Soul Trap On Hit".

You can either Soul Trap something to fill a Soul Gem, or let Soul Stealer just keep your weapon fed in combat.

I think the one you are thinking of is Soul Squeezer. No wait that makes you get more magicka out of soul gems... I know which one you are talking about though.

And if you don't like it you don't have to get it. It will be fine if let's say, Azura's Star returns. Or you keep plenty of small soul gems on you.

...I guess that's something you have to account for, then.

A shame they make it a prerequisite for the awesome Oblivion Binding perk.

Do we know if soul gems still get destroyed when drained?
