The Rogue is a very fast unit that can attack at a medium range. Her main attack has double attack power with two attacks each time, similar to a Tier 5 wizard. She originally was unlocked in level 6-2, but after the update, she is available to purchase during the Frostburn campaign.
For her regular attack she throws two daggers at a medium range (Tiers 1-3), and later two large shurikens in Tiers 4-5 (ninja stars).
Her main special from Tiers 1-3 is a backstab sort of attack. She will teleport behind the enemy unit, and continue her normal attack.
