Soul Crystal lvl 8 ??

By looking at the guide on "Lineage 2 Stratic" I can read how to raise a crystal to lvl 7... but for lvl 8 there are no informations :(

So on what mobs can I raise a soul crystal to lvl 8?

I just found out I dident have to drop the crystal to the floor to get more the on at the time(from Jurek in Giran).
I just aborted the quest and then activated it once more. That way I got an ekstra soul crystal in my inventory :)

Kill doom knights by devistated castle or fobiden gateway. You can lvl it all the way to 10 on them.

How long would you think it takes to lvl a soul crystal to lvl9-10, when taking into consideration that some of them might brake on the way to lvl 9-10?

You can get up to stage 8 off Doom Servants, up to stage 9 on Doom Troopers/Warriors, and up to stg 10 on Doom Knights.

If I start with 10 stg 0 crystals I can usually get 1-2 stg 10s. It usually takes me about 2, 3-4 hour killing sessions to stage all (or break all).

ok thx for the answer.

Do you lvl the crystal with a fighter or mage class?

.... and

is it like normal lvl'ing, is it easier to get the first lvl's and then a lot harder to get the last one?
