Castle Necrocom
 

Does anyone know where i can find this castle? Thank you!

It is in a cemetery area in the death valley, use the book of life in ellinia to go there (can't remember if you spawn closer with the book of life in great forest, or with the one in magic valley).

*Little help in white ->It is one of the toughest battle in the game, so be prepared. Remember to "magic shackle" the artifact :)

to be more accurate of the location, is in most southern part of the death valley map guarded with black dragons and ghost inthe cemetary etrance, you can avoid those dragons and ghost by coming from the sea, and timing to go to castle when dragons are coming out from castles etrance...

The main problem with the battle is there are 3 sources of raise dead spell. The udnear s itdels are easy. So get 1 stack of thorns with you and start turning the killed enemy stacks in thorns.

There are many ways to counter the raising such as magic lock, thorns, totems, demon portals, demon summoning, necro call, ice ball, phantoms, etc.

If you are playing a mage, necro call will be your friend in this battle (at least one of many friends you could use ;) ). Take out his necromancers (if there are any in his army - for me, there were 2 stacks) with ranged units/spells and necro call them (necro call lvl3, possibly with necromancy, raises a lot of necromancers). Karador resurrecting his troops shouldn't be a problem anymore for the rest of the battle ;)

the imba way to beat at any difficulty Karador is to come with one stack of Green Dragons :) and to use invisibility on 'em. Enemy should skip his turn every time.

Probably only a valid strategy for mages, I couldn't keep my mana up and do enough damage with a warrior so I went to Demonis first, came back, kicked his ass with no losses, and moved on.

It's 100% possible even for Warrior ;) As well as the best party to beat the last boss is...a single stack of faeries (beatable by lvl 13 with only one stack of faeries. diff=impossible) :)

Well it seemed pretty much impossible for me, between the stack's mana drain ability and mana spring/poison rain combo (which for some reason only triggered a few times for me), there just wasn't enough mana to keep invisibility up, much less use any other spells, especially once Concentration gain started falling. So I was either doing something wrong or I just couldn't double as a mage at that time.
