Morale System#

Morale Modifiers#

Morale is the hidden deciding factor of battle in Total War: ATTILA. The table below gives the direction in which each factor acts and the basis for judging it; the specific magnitude is not published as a fixed value in the game and varies with version, unit morale attributes and the state of the battlefield, so go by the hover tooltip on the unit panel.

Factor	Direction of effect	Basis
Battlefield advantage	The winning side’s morale rises, the losing side’s falls	Updates in real time with the balance of forces and the state of the fight; the bigger the advantage, the closer the disadvantaged side is to breaking
General’s presence	When a general dies or routs, nearby units’ morale drops sharply and a chain collapse may follow	The radius and magnitude vary with the general’s attributes and the distance to the units
Exposed flank	Units attacked in the flank lose morale noticeably	Cavalry flank attacks are especially effective
Attacked in the rear	Units attacked from behind suffer severe morale damage and break most easily	Stacks with flank attacks
Fatigue level	The deeper the fatigue, the more fragile the morale	See the table below for the tiers; the exact penalty follows the hover tooltip
Unit losses	After losing more than half its strength, morale drops sharply and the unit approaches rout	The trigger threshold varies with the unit type’s morale attribute
Nearby allies routing	Witnessing allies rout shakes the army’s resolve	The closer they are and the larger the rout, the more obvious the effect
Terrain advantage	Units holding high ground gain morale	Related to the height difference and the gradient
Bad weather	Storms, dense fog and other severe weather put pressure on morale and visibility	The direction of the effect follows the in-battle tooltip
Plague infection	Units infected with plague are under continuous morale pressure	Duration varies with how far the plague has spread

Fatigue Tiers#

In Total War: ATTILA, unit fatigue is divided into six tiers, from the best condition to completely spent: Fresh, Fine, Winded, Tired, Very Tired and Exhausted. The developers have not published exact coefficients for each tier; hovering the mouse over a unit’s fatigue indicator in battle or on the campaign map shows the current tier and the live figures. The table below only gives a description of each state and the direction of its effect.

Tier	State description	Direction of effect
Fresh	Full of stamina, in the best condition	All combat attributes are at normal levels, with no penalty
Fine	Stamina slightly depleted	Attributes are almost unaffected; only a slight change is visible on the panel
Winded	The unit is starting to breathe hard	Melee attack, defence and movement speed begin to fall
Tired	Stamina noticeably depleted	Attack, defence and charge bonus drop further, and the duration of sprinting shortens
Very Tired	Stamina near its limit	All combat attributes are clearly impaired, and morale wavers more easily
Exhausted	Stamina completely spent	Combat effectiveness drops sharply, and the unit routs very easily once engaged

Fatigue Accumulation and Recovery#

Fatigue accumulates continuously as a unit acts. The main sources and means of recovery are as follows:

Action or condition	Effect on fatigue
Marching and forced marching	Long-distance movement makes a unit enter the next battle already fatigued, and forced marching drops a tier faster
Charging and melee grinding	Accumulates continuously within the battle; units that get bogged down in melee after a charge drop a tier fastest
Sprinting	The fastest way to burn stamina within a battle; always keep some in reserve before charging into the enemy’s face
Mountain, snow and desert terrain	Accelerates fatigue accumulation
Standing in place	Once movement and sprinting stop, fatigue recovers over time; recovery is faster out of combat
Garrisoning a settlement and camping to rest	The main way to recover stamina on the campaign layer

A rule of thumb for the rhythm of rest and replenishment: before engaging, bring your main force back up above “Winded” before committing it, and leave the decisive charge to reserve cavalry that is still Fresh; units that are already “Exhausted” should only be used to watch the flanks or to feint, and should no longer be thrown into a frontal grind.

Fatigue Management, Winter Marching and Replenishment#

The core of fatigue management is “trading condition for results”: the same unit engaging while Fresh and engaging while Exhausted amounts to two different battles.

Interaction with winter marching:

Winter marching causes additional attrition, and after long-distance movement stacks with fatigue, a unit may already have dropped to “Very Tired” or even “Exhausted” before it ever engages.
Rule of thumb: do not force march in winter unless necessary; when a long march really is required, rest in place for one turn after arriving and bring fatigue back above “Winded” before engaging.
The harsher the climate, the heavier the attrition; the exact deduction varies with the regional climate and faction traits, and follows the end-of-turn summary.

Interaction with the replenishment mechanic:

Fatigue is recovered by resting, but actual losses from winter and long marches have to be refilled by replenishment; both must be folded into your marching plan together.
Replenishment speed depends on the territory the unit is standing in, local supplies and building bonuses, and is slower in winter and in enemy territory; the exact coefficient follows the unit panel display.
Therefore the general rhythm for advancing in winter is: better to slow down and let your armies finish resting and replenishing inside your own territory before committing them to the next battle.
General traits and technologies can mitigate winter attrition and soften the impact of fatigue, and are the operational direction that winter-warfare factions should prioritise.

Terrain System#

Terrain Types and Effects#

The effect of terrain on movement and combat is described here in terms of direction; the exact slowdown and stamina cost vary with unit weight and terrain gradient, so go by how it actually plays out in battle.

Terrain	Movement effect	Combat effect
Plains	No noticeable effect	Good for cavalry charges, open sightlines
Hills	Slight slowdown	Elevation advantage, good for defence
Forest	Noticeable slowdown	Cavalry advantage is limited, ranged sightlines blocked, can cover an ambush
Jungle	Major slowdown	All units move slowly, high ambush success rate
Swamp	Severe slowdown	Heavily armoured units are especially sluggish, stamina drains faster
Mountains	Major slowdown	Excellent defensive terrain, hard to surround, stamina drains faster
Rivers	Severe slowdown	Extremely vulnerable while crossing, cannot form up
Desert	No noticeable slowdown	Fatigue accumulates noticeably faster
Snow	Noticeable slowdown	Fatigue accumulates faster, winter marching attrition is heavier
City streets	Noticeable slowdown	Good for infantry street fighting, cavalry cannot deploy properly

Elevation Advantage#

The side holding the high ground has the better of it on both attack and defence: from above, charge momentum is greater, melee exchanges are easier to win and ranged units get better ballistic coverage, while the side attacking uphill has a weaker charge and burns stamina faster. The greater the height difference, the more obvious the advantage. The exact magnitude of the advantage varies with gradient and relative height, and follows the in-battle performance and hover tooltips.

Weather System#

Weather	Visual effect	Combat effect
Clear	Bright sunshine	No additional effect
Cloudy	Overcast sky	Sightlines drop slightly
Light rain	Steady drizzle	Ranged accuracy is slightly affected
Heavy rain	Wind and torrential rain	Ranged accuracy drops noticeably, sightlines restricted
Dense fog	Extremely low visibility	Sightlines greatly reduced, ambush success rate rises markedly
Sandstorm	Sand filling the sky	Ranged shooting is severely disrupted
Blizzard	A world of ice and snow	Sightlines restricted, additional pressure on stamina and morale

Siege Mechanics#

Siege Equipment#

Equipment	Function	Notes on use
Siege ladders	Get up onto the walls	Erected on the spot by infantry, the cheapest option, but vulnerable while climbing
Battering ram	Break open the gate	Advances slowly and needs units to cover it
Siege tower	Carry large numbers of soldiers onto the wall	Better protected, but takes up a lot of deployment space
Onager	Destroy wall sections or buildings at range	High impact, average accuracy
Catapult	Shoot accurately at defenders on the walls	Good for suppressing troops on the ramparts
Fire arrow cart	Fires flaming arrows for area damage	Good for burning buildings and creating chaos

How long each piece of equipment takes to build and whether it is available depends on the length of the siege, the composition of the forces involved and technology bonuses, as shown in the siege interface; the longer the siege lasts, the more complete the equipment you can usually build.

Battle Difficulty Settings#

Battle difficulty affects the AI’s tactical decision-making ability and the bonuses applied to both sides’ units; the exact magnitude of the bonuses at each difficulty follows the in-game difficulty description and actual play.

Difficulty	Characteristics	Who it suits
Easy	AI decision-making is weaker, player units get a slight bonus	Beginners practising
Normal	Neither side gets extra bonuses	The standard experience
Hard	AI decision-making is more aggressive and it gains some attack and defence bonuses	Challenging
Very Hard	AI gains obvious attack and defence bonuses and its decisions leave almost no openings	Extremely challenging

Battle Auto-resolve#

Factor	Direction of effect
Relative numbers of troops	The largest influence
Unit quality and counter relationships	A large influence
General ability and retinue bonuses	Some influence
Terrain and fortifications	A secondary influence

Auto-resolve usually costs you more losses than manual command, so fight manually when you can win; the outcome estimate can be checked against the win/loss tendency indicator shown in the interface.

Battle Victory Conditions#

Condition	Explanation
Annihilate the enemy	Destroy or rout all enemy units
Capture the objective	Remain inside the objective area for a set time
Kill the enemy general	Kill the enemy general, causing enemy morale to collapse
Time expires	The defender still holds the objective when time runs out
