Grand Conquests (Japanese:大制圧戦Great Conquest Battle) is a game mode inFire Emblem Heroes, added in theSnow and Ash update and starting its first event on April 13, 2018.

Grand Conquests is a game mode that allows players to join armies in an attempt to conquer as much of a game board as possible, much in the vein of games such as the board gameRisk. Each Grand Conquests event lasts for six days, with three battles per event, each battle lasting twenty-two rounds over two days.

Gameplay

During each battle of a Grand Conquests event, players are assigned randomly to an Outrealm and to one of three armies within that Outrealm, each army led by eitherAlfonse (the red army),Sharena (the blue army), orAnna (the green army). During a round, players can choose a space in which their color is adjacent to a space of another color (i.e. someone on the blue team can choose any space that is either a blue space adjacent to a red or green space, or a red or green space which is adjacent to a blue space), use some stamina, and initiate a battle; the battles themselves work similarly to theRival Domains mode, right down to offering the same four difficulties of Normal, Hard, Lunatic, and Infernal. The stamina used in Grand Conquests is specific to this mode, and can be refilled by using aConquest Lance. The more battles an army wins on a specific space increases the chances of that square turning that army's color for the following round.

Battles on each space may at times be affected by certain effects that affect units of a certain movement type; one effect for each movement type involves increasingAttack,Speed,Defense, andResistance by +4 each on all units of a certain movement type. The other effect for each movement type is unique to that movement type: infantry units may receive a cooldown acceleration effect for special skills, armored units may be allowed to move an additional space per turn, cavalry units may guarantee follow-up attacks when initiating combat, and flying units may move adjacent to spaces adjacent to flight allies within two spaces.

Area Effects

Various effects can appear in any area on the map, and once this occurs, players can take advantage of that specific effect.

Effected Unit	In-game Description
	Grants Atk/Spd/Def/Res+4 to infantry units.
	Grants Atk/Spd/Def/Res+4 to armored units.
	Grants Atk/Spd/Def/Res+4 to cavalry units.
	Grants Atk/Spd/Def/Res+4 to flying units.
	Grants Special cooldown charge +1 per attack to infantry units during combat. (Only highest value applied. Does not stack.)
	At start of turn, armored units can move 1 extra space. (That turn only. Does not stack.)
	If cavalry units initiate combat, units make a guaranteed follow-up attack.
	Units can move to a space adjacent to a flying ally within 2 spaces.
