When two rival players forces engage, either in open battle or during a siege of a city, combat takes place in a separate phase of gameplay within a hexagon grid-based 3d battlefield where units are designated movement and space. Each side can lead multiple armies into battle with up to six units per army, many represented by multiple soldiers forming ranks as a single combatant that reflect their overall health (as figures are killed, their combat ability does not diminish until the unit’s health reaches zero) while others are shown as single yet stronger characters. Both sides take turns to move and utilize their units while also being able to grant abilities that can enhance their effectiveness in combat, including magical spells that can also be used to boost unit capabilities, summon in new units and call down potentially very devastating area of effect attacks. Spells that leaders have learnt are usable in every battle regardless of his or her presence while others require hero units to be present, spell usage being limited by their mana pool. Units can also make use of the battlefield environment, such as defensive walls during city sieges, foliage and being able to make use of a flanking manoeuvre where attacks from a units rear can be more effective.
Units are allocated “action points” used for attacking, defending/retaliating and using special abilities, separate from yet dependent on their choice of movement shown by colour coding their choice of hexes they can act within. For example, if a unit does not move during their turn, they can perform up to three actions with the surrounding hexes displayed as green to the player, whereas if they move, they would appear orange and could now only perform two actions and finally one with red hexes. Any remaining action points a unit has or does have carries over into the opposition’s turn, always having at least one left regardless of how far the unit moved prior. These remaining action points can be used to retaliate against any attacks they received from enemy units during the opposing player’s own turn. It is also possible to expend action points entirely, potentially leaving units unable to move and/or retaliate themselves. Other options include the ability to just sprint or guard, greatly raising movement and defense respectively and evoking various different status effects such as stuns and poisons and damage enemy units that move into adjacent hexes.
