You should know your own strenght better not to enter some creepy dark place with 13 ghosts in it. The last time I went in there, I was lv 9 Warrior (you won't survive as mage, especially ELVE) and still having trouble fighting them.
Yes, those headless zombies are very scary and deadly (it can stun you too) I am sure you rather fight a troll (cause troll dunno how to use shield).To solve your problem:
-1st: Do what Siberys said-Option-Random Counter-less (you fight less monsters, which make you safe, but slow level up) Here is a thing about this option "what there already there, what not be there won't be there" Meaning all the monster that there when you save game will still there. However the next wave they won't spawn as much as it should be.
-2nd: Those headless, you won't be able to fight them hand-to-hand, 1 wack would make you fly, especially if you are Elve or Mage. "Use range weapon and keep the distance" . Now, get out the tomb and get yourself a bow or dagger (to throw), buy some potion too.
-3rd: Then go back in the tomb, run faraway from the Headless, take out your sword start swinging to rid all the bats (keep the distance from Headless)
When you done = only you and the Headless left. Now switch to your range weapon and start nail him down, he will block most of it, but also take most of the attack. That should solve your little "Scary" movie problem.
PS: 1) I think there are at least 2 and at most 4 in the catacomb. Listen to the footstep sound to know and get ready.
2) If he get to close, raise your shield to block to avoid getting stun. However, that freaking huge axe will destroy your shield in 10 hits, since you can only carry one of each type of shield, make sure you have 2-3 different types of shield in your inventory.
3) Make sure you know some magic attack or carry magic weapon (y? those white ghost ONLY take damage by magic and they can freeze you, not that deadly but very anoying)
4) Use shield to block smoke when you fight the BOSS. (also recommend to keep distance and use range vs. Boss)
5) DO NOT stand behind the mummy coffin while you open it. If you get stuck, that your problem now, and it gonna cost ya. (
BUG!!!)
Well hope all of these will help some new people
, since this new game got a hive of bugs.
Oh!!! one more thing, if you really trapped by the monster. You have no choice but to die, they should walk away from your dead body. Wait until they far away the revive and run like hell.
