Terrain System
Terrains are persistent or temporary entities existing directly on the battlefield. They operate identically whether deployed prior to the game (Decorative Obstacles) or generated mid-game via Spells/Abilities.
Terrain Types
- Blocking: Restricts both Movement and Line of Sight (LoS). Units cannot intersect or traverse Blocking terrain. Exception: Units possessing the keyword bypass the obstacle during movement, but cannot legally end their movement stationed upon it.
- Traversable: Permits free Movement. Units may enter and occupy Traversable terrain. Applicative effects (e.g., Poison damage, Healing) trigger exclusively based on the specific terrain's card text.
Terrain Rules
- No Stacking: A terrain piece cannot physically intersect or overlap another terrain piece.
- Stack Interaction: Pre-game decorative terrains bypass the Stack entirely. In-game terrain generation relies on a Spell/Ability entering the Stack. The terrain physical materialization occurs strictly during the spell's resolution.
- Destructibility & Targeting: Permanent terrains possess a printed HP value and can be legally attacked. They are classified strictly as "Structures", not "Units". Spells dictating "Target Unit" cannot affect Terrains; the spell must state "Any Target" or "Structure". Upon reaching 0 HP, the terrain is destroyed and removed. Temporary terrains lack HP and cannot be attacked; they vanish when their listed duration expires.
