The movement of a unit is determined by its movement stat, its skills, and the terrain it moves across. If not impacted by any other factors, a unit can move to tiles whose distance to the unit's starting tile is not more than its movement stat, as measured using Chebyshev distance. However, this is affected by the terrain the unit move across, the presence of roads, as well as some other factors. A unit may only move once per turn (besides the use of the dash and escape skills), and each tile can only be occupied by one unit at a time. A forced unit spawn occurs when an unit is spawned on a tile that already has an unit on it.
A unit's movement stat determines how far it can move every turn. Moving from one tile to an adjacent tile incurs a cost of 1, but moving between tiles with roads has a cost of 0.5.
Terrain[]
Certain types of terrain impact movement. Forests without roads and mountains block movement. Units cannot move through them (they can move onto them, but no further in the same turn). Also, units cannot move into clouds (the fog of war).
Most land units moving into a Port will be turned into Rafts and will be unable to perform actions for the rest of that turn, even if they had excess movement points or had not attacked. However, units with the float or Fly skills are not affected.
Zone of Control[]
All units exert a passive Zone of Control onto enemy units. This takes priority over movement bonuses conferred by Roads or Polarism (see #Glide). A unit that moves to a tile adjacent to an enemy unit cannot move any further, even if the unit had excess movement points.
This does not prevent units with the Dash skill from attacking after moving, and the Zone of Control goes away when the enemy unit is destroyed.
A unit that starts its turn within Zone of Control may be able to move out and then back into it, occasionally leading to seemingly impossible but valid movement destinations.
Roads[]
Movement between two tiles with Roads (or a Road and a city) requires only 0.5 moves, ignoring the movement penalty from Forests (it is impossible to place Roads on Mountains) but not Zone of Control. This only applies to Roads in friendly territory or in neutral territory, but not when moving onto Roads in enemy territory. Bridges follow these same rules, but with the added benefit of allowing land units to cross one tile of water.
In order to utilize bonus movement from roads, you need to place a road where your troop is standing and then on the following tile. City tile works as a road tile. Roads can be placed on villages, but they disappear when the village is claimed.
When calculating movement cost of a tile, the game rounds up - meaning even if you have 0.5 movement points remaining, you can still move onto a tile costing 1 or more movement points. The place the unit ends up is irrelevant - you don't need a road at the final tile and movement is not blocked if final tile is an obstacle.
Glide[]
As Polaris, researching the unique Polarism technology unlocks the Glide skill, which halves the movement cost of moving into ice tiles, functioning more or less as if every ice tile had a Road on it. However, moving from an ice tile to a land tile with a Road still costs a full movement point.
Forced Unit Spawns[]
A forced unit spawn occurs when an unit is spawned in a tile that already has a unit on it. The unit that is already on the tile is pushed in a specific direction. Forced unit spawns can happen when a super unit spawns in a city, a Ruin spawns a unit, or ∑∫ỹriȱŋ spawns a Polytaur or Navalon. The forced spawn of super units are commonly used in besieged cities to push out the invader, and the forced spawn of Polytaurs are commonly used to "boost" the movement of friendly units.
The push order for forced unit spawns determines the direction in which the unit already on the tile where the new unit is spawned will be pushed. The push order is as follows:
- Friendly units that previously moved will be pushed in the same direction of their movement.
- Example: A friendly unit that previously moved north will be pushed north.
- Enemy units that previously moved will be pushed in the opposite direction of their movement.
- Example: An enemy unit that previously moved north will be pushed south.
- Ranged units get pushed in the direction of their last move or last attack.
- Units that were not previously moved will be pushed toward the center of the map.
- If the city where the unit spawns is on the exact center of the map, the unit will be pushed south.
- If the tile where the unit is supposed to go is occupied or impassable, it will try counterclockwise and then clockwise one tile at a time until it finds a free tile, or if there is no free tile, it will be removed from the game entirely. This does not count as a kill for the Gate of Power, nor does it count as an attack for the Altar of Peace.
Unit Skills[]
- This section needs to be updated.
The unit skills listed below impact movement in some way. (Units without any of these skills are called “land units”.)
- Carry (Raft, Scout, Bomber, Rammer, Juggernaut, Dinghy and Pirate): The carry skill allows a unit to carry another unit inside and travel on water. (Navigation or Free Diving must be researched to travel on ocean tiles.) A unit with the carry skill can move to land tiles adjacent to water, but doing so turns it into the unit it was carrying and ends the unit's turn.
- Fly (Phychi, Baby and Fire Dragon): The fly skill allows a unit to ignore all movement barriers imposed by terrain. However, units with the fly skill cannot utilize roads.
- Navigate (Navalon and Raychi): The navigate skill allows a unit to move across shallow water and ocean even if the prerequisite technologies are not researched. Units with the navigate skill cannot move to land tiles, except they can capture cities (but not villages).
- Skate (Mooni, Battle Sled, Ice Fortress): The skate skill doubles movement on ice but on land limits movement to one and bars units with it from using the dash and escape skills.
- Creep (Hexapod, Doomux, Raychi, and Centipede): The creep skill allows a unit to ignore movement penalties due to mountains and forests, but disabling bonuses from roads. It also does not allow traversal over water.
- Sneak (Hexapod, Cloak): The sneak skill allows a unit to bypass barriers presented by tiles adjacent to enemies at no cost.
- Boost (Shaman): The boost skill grants a unit the Boost unit ability, which increases the movement of all adjacent friendly units by 1 until their next action (excluding moving).
Note that the Amphibian, Tridention, and Crab's movement are reduced by half on land.
