Shekels

Shekels are one of the main currencies in Castle Doombad, the other being Evilness. They are gained from the following: Heroes can drop coins, giving 5 Shekels. You also get a set amount upon finishing a level, that scales up with the difficulty. Completing a level without the Princess being captured will give a Crown Bonus, which gives you a Crown for unlocking Mastery Stages, Chapters and doubles the Shekels you gain for completing the level. They are used for unlocking and upgrading all traps and minions.
