What Skills do you have ? And have you still some skillpoints left ? Which Level are you now?
I was level 19 when do that battle .
I started as a Ranger and later on go more and more fro the Priest skilltree & concentrating on magical damage weapons (bow, mace, sword, eetc) and the good thing is now I go also for more Mage skills.
Are you a PURE archer with Dexterity upgraded ?
The minions of Laiken are dealing melee damage and Razakel also + magic damage (I think Fireball or something stronger) ... as a pure archer it's indeed very dangerous !
I fail 3 times trying different strategies ...
The one that succeeded was putting 2 points in "Firewall" and always concentrating on killing Razakel !
But to say: I summoned also my Ghost (5/5) and my Creature (Ranger Head : Fireball L6).
I hope you find a way to kill Razakel ! If Razakel is dead the battle is over !
