Just kill a filthy greenskin.

Touch a scruffy skull of fate.

During your adventures you will find blue magic potions. Spend them at the magician in the village and learn three new skills/abilities.

To unlock the dwarf you have to complete the map "Searching for the Dwarf".

To unlock these three heroes you have to complete a certain number of dungeons. Then just visit the tavern to hire them.

The first one you will probably unlock during your adventures.

Collecting 100k gold requires some effort. Apart from the bonus levels (where you will get a lot of gold) you can repeat all other maps to earn cash.

IMPORTANT: The game counts the total amount of gold you grab. So you don't have to worry about spending money at the merchant... or at the gravedigger.

Tip:
Have a look at the Workshop. There are maps which make it very easy to gather 100k gold :)

To create the talisman you must find the three parts of it. You can find them in the following maps:

• Descent to Chaos
  
• Hall of Black Mirrors
  
• Castle of Doom

After finding all parts, the talisman will be created automatically and you can continue your way on the map "Talisman Gate".

Just kill the nasty Executioner in "The Executioner".

To get the first achievement you have to defeat the Evil Sorcerer on normal difficulty.

For the second achievement you have to play on hardcore mode and kill the Evil Sorcerer.

IMPORTANT: Unfortunately it is not possible to play the game only on hardcore to get the achievement "Hardcore" and "The Sorcerer" together.

Just play a map with someone online.
