Orcs Must Die!: Nightmare 5 Skull Guide 2021

No videos, just a simple guide you can print off and keep with you as you play, instead of having to constantly exit the game to watch videos.

 

Basic Introduction

If you are new to the game I recommend playing it through fully on apprentice, then war mage.
When nightmare is available play each level on War Mage first to get 5 skulls as a practise round, then switch to nightmare for the same run.

Standard setup:

– Steel Weaver + first skill (Death Augmenter) to get more money from kills
(update it for either traps or archers where appropriate)
– lightning/fire (to be used where they enter and near traps)
– ice + sword (for trolls/hunters)
– fire ring for ice trolls

Standard wall setting:

– barricade leaving one space (a kill zone)
– tar
– mace
– grinders
– brimstone in front
– spring traps behind (sometimes) or archers (other times)
