Dredge Slag Slinger

General
Slag Slingers are the basic ranged unit of the Dredge army. They have slings that they use to fire rock-like projectiles in a range of 2-5 tiles, just like the human Archers. They don't have high stats but their increased range can make them difficult to reach with your melee units, especially when safely behind their bulky allies, Stoneguard or Scourge. Slag slingers have no active ability but their passive, Back Off (see below), makes them hard and unpredictable to handle.

They come in three ranks: regular, Marksman and Veteran. The higher ranks, distinguished by different colors, are encountered later in the game or in the Hard difficulty setting.

Passive Ability: Back Off
When a Dredge with the Back Off passive receives either Strength or Armor damage, it will move 3 tiles randomly, in a general direction away from the attacker.

Notes:
 * The random nature of Back Off makes Slingers hard to get, especially when you want to Break them and follow-up with a Strength attack.
 * Always be cautious when attacking a Slinger. Back Off movement can expose your allies to attacks from back-line Dredge that were blocked by that Slinger!
 * The exact conditions under which the Back Off passive triggers are not entirely clear; for example, Splinter damage does not trigger it. What is certain is that Back Off can only be triggered once between two turns of the Slinger.
