Units

Recruiting Armies

Armies and Militias are the primary methods of recruiting and controlling units in Ymir. The in-game tutorial provides a full explanation for how to create, reinforce, and manage them in the worldmap.

As you progress in the game, new unit types automatically become available for recruiting once you have the equipment for it. So for example, you can scavenge bows from an event and produce leather clothes, then recruit bowpigs even without the technology that allows bows production.

Where Coin costs are listed, they only apply once players have unlocked the State Treasury

Stats Comparison

Combat in Ymir is entirely AI-controlled, so players often put a great deal of effort into planning the composition and positioning of their troops ahead of possible engagements. As a result, the stat system in Ymir may be more complex than most players have encountered in other games.

While the exact combat formulas are not currently known, the in-game tooltips provide the following summaries for each stat:

Base Stats

Strength

A procedurally calculated score based on all of the units stats to estimate its overall level of combat abilities.

A basic measure of a units overall strength. Affects how much Loyalty is gained from armies or lost from militias when units are stationed in a Territory.

Movement

The movement speed of the unit on the battlefield. It also affects the overall movement speed of the formation in the worldmap.

Mass

The mass of the unit combined with its speed gives a damage bonus when charging and a skill bonus in melee combat versus lighter units.

Carrying Capacity

The amount of resources this unit can carry. The formations inventory capacity is the sum of all its units carrying capacity.

Armor and Toughness

In combat units do not have a health value, but die from a single landed hit which penetrated their Toughness and Armor. When a unit is hit - the game rolls 2 dice, one after another, to determine if the unit has survived the attack. The unit has to roll a good outcome on either one of the dice to survive.

Toughness

The resistance of the unit to damage. The higher the toughness is compared to the received damage, the lower the odds of being killed by the hit.

Damage Resist

When a unit is hit, the game determines whether the unit resists it or not, by rolling a die.

This roll is affected by the units Toughness and by the attackers Damage like this: Damage equal to Toughness would give a unit 50% chance to resist the blow, with every point difference between damage and toughness changing the % by 12, up or down accordingly (For example: A unit with 3 toughness has a 50% chance to resist an attack with 3 damage. And a unit with 2 toughness has a 26% chance to resist a blow with 4 damage).

More Damage				-	More Toughness
-4	-3	-2	-1	0	+1	+2	+3	+4
2%	14%	26%	38%	50%	62%	74%	86%	98%

Armor

Gives chances to deflect enemy hits. Odds are increased versus ranged attacks.

Armor is a stat that works like Toughness, except that it provides a percentage chance to deflect the attack, for every unit of Armor the unit has.

Each point gives a 14% chance to deflect a melee hit OR a 16% chance to deflect a ranged hit (A unit that has 3 Armor has a 42% chance to deflect a melee blow and 48% chance to deflect an arrow hit).

There is always a minimum chance for a unit to still be hit through all the armor - some one in a million arrow may kill your armored elephant.

High armor units are very durable and may survive for longest. Units that deal more than 5 damage per hit reduce Armor with their Armor Penetration bonus (refer to Damage below for more information).

Wall Cover The Cover Bonus from Walls can also affect Armor and make a unit practically immune to arrows (The cover bonus provides Armor equal to the value it gives).

Walls provide the following amount of Cover:

Palisade	Mudbrick	Cobblestone	Brick	Stoneblock
5	4	6	5	7

Damage

Damage is compared against enemy Toughness and Armor values to determine whether the unit has deflected the blow in relevant checks. See more in the Toughness & Armor paragraphs above.

Penetration Bonus A damage value above 5 provides a Armor Penetration bonus that reduces the enemy Armor by 1 for every additional point of damage. (For example: An Axepig's damage of 9 provides an Armor Penetration bonus of 4, reducing enemy Armor by 4).

Wall/Gate Damage

Damage also determines the speed of wall/gate breaking by a ram during city invasions. It has a linear effect, with 9 damage unit being 3 times quicker then 3 damage unit.

Damage Types Attacks are split into two types: Melee, and Ranged.

Melee

Offensive and Defensive Melee Skill

The ability to hit enemies or dodge their attacks in melee attacks. Chances to hit depends on the differences between the offensive skill of the attacker and the defensive skill of the defender.

Melee Damage & Attack Speed

The amount of damage inflicted to the enemy when successfully hit with a melee attack. Attack speed etermines the average amount of attacks dealt per turn.
Damage above 5 gives an armor piercing bonus reducing the enemy's armor saving rate.

Reach

Represents the maximum distance at which the unit can strike its enemy in melee attacks. A higher reach than the opponents gives a skill bonus to hit.
A reach above 2 also gives a bonus to hit in melee against units of higher mass (Excluding spears vs cavalry).

Ranged

Ballistic Skill

The ability to hit distant enemies in ballistic attacks. Difficulty is increased by distance of the target and its movement speed.

Ballistic Damage & Attack Speed

The amount of damage inflicted to the enemy when successfully hit with a ballistic attack. Attack speed determines the average amount of attacks dealth per turn.
Damage above 5 gives an armor piercing bonus reducing the enemys armor saving rate.

Height Bonus

Attacking from above or below another unit improves/reduces the amount of damage a unit will do:

• Attacking from above will give +1 damage per tile height difference.
• Attacking from below will give -1 damage per tile height difference.

The Height Bonus is capped at -3/+3.

Range

For ballistic attacks, the maximum distance in terrain tiles this unit can target enemies.

Civilian Units

All civilian units are available from start of the game, since their equipment does not require any knowledges.

Ranged Units

Ranged units are a mainstay of city defense throughout the game, but always perform best when they have either a Wall or melee formation between them and the enemy. While fewer options are available than melee units, each tier increases both the recruiting cost and attack range at which they can engage enemy formations.

Cost and Requirements:

Unit		Type	Cost Per Unit
			Resource(s)			Cost	Upkeep
	Rock Thrower		Stone			-	0.5
	Javelineer		Javelin			1	0.6
	Bowpig		Bow	Leather Clothes		2	0.7
	Longbowpig		Longbow	Padded Armor	Light Helmet	3	0.8
	Crossbowpig		Crossbow	Brigandine	Light Helmet	4	0.9

Ranged units benefit from an alternate set of Attack stats when performing a ranged attack on enemy units, which behave like their melee equivalents with some minor differences:

• Ranged Attack Rate - (Not shown in-game) Determines the time between ranged attacks. Continues for as long as units have ammo remaining.

• Ranged Damage - Amount of damage inflicted to the enemy when hit by a ranged attack.

• Ranged Skill - Provides a bonus to hit enemies based on this unit's Ranged Skill. Does not provide any bonus chance to evade attacks.

• Range - The maximum distance (in terrain tiles) at which a ranged attack can hit enemies. Does not provide any bonus hit chance. If attacked by an enemy unit outside of their available Range, formations will attempt to charge them in melee combat instead.

Range attack modificators:

• Ratio of target distance to max Range: modifies skill. bonus below 40%, malus above it.
• Height difference: +/-1 damage per 5 heights, +/-1 skill per 5 heights.
• Target under cover: adds cover level as armor to target.
• Target is moving: skill malus proportionnal to target moving speed
• Target in melee: skill -50%
• Is embarked: skill -1 damage -1
• Target is embarked: target's armor -50%
• +1 attack per 5 units in the troop
• -6% skill per unit below 5 units in the troop

Mounted Units

Mounted units become available at later stages of the game and are best employed as separate Armies to take advantage of their high movement speed (the slowest units in an Army set overall worldmap speed). They are especially useful for skirmishes with smaller Armies and raiding territories for resources, where slower units might be left open to follow-up attacks by enemy forces.

Mounted units benefit from a "mobile attacker" trait making them considered as moving even when in melee. This means they benefit from the moving cover against enemy range attacks event when they are fighting in melee, further increasing their strength against range units.

Tamed Units

Although they're exceptionally rare, players can sometimes obtain Animal units through "taming" exploration events when moving Civilian units. These animals cannot be re-recruited if they are lost or disbanded, but have nearly perfect stats to serve as early game scouts. Although new units of animals can't be recruited already existing units can be reinforced using animals from your stockpiles, as some of the animals you can get are breedable at ranches this means that you can more easily replenish losses to those units.
