Native terrain
Native terrain is a creature's "home" terrain type. It gives creatures fighting in their native terrain +1 attack, +1 defense and +1 speed. Additionally, a hero moving on a terrain that causes movement penalty with only creatures native to that specific terrain suffers no movement penalty.
Towns and their Native Terrains:
- Castle – Grass
- Rampart – Grass
- Tower – Snow
- Inferno – Lava
- Dungeon – Subterranean
- Necropolis – Dirt
- Fortress – Swamp
- Stronghold – Rough
- Conflux – Grass
- Neutral – Dirt
Sieges are always fought on town's native terrain (e.g. inferno town sieges are fought on lava).
