A character has life points. When the character receives damage his hit points drop by the same amount. When a character reaches 0 points of view or less he dies and is removed from the map, making room for the characters still alive. In addition, it is possible to heal characters with healing skills. However, it is not possible to exceed the target's maximum hit points, any exceeding will be ignored.

The characters are not immune to damage from their allies, the player must be careful not to attack his characters. Likewise, it is quite possible to heal an enemy.

A character can receive shield points. These shield points absorb any damage the character takes for a 1:1 ration. There is no limit to the amount of shield points a character can receive, but they disappear at the start of the player's turn who gave the shield points.

There is a certain type of damage that ignores shield points and attacks health points directly. In this cell the life points are lost as if the character had no shield points and dies when he reaches 0 life points, even if he still has shield points.

Each character has a size category. This value determines the number of spaces the character takes on the map. The categories present in the game are currently 1, 2 and 3, which respectively represent 1, 7 and 19 cells arranged in a circle.

Skills whose effect covers multiple cells only affect each character hit once, even if the character is on more than one of the hit cells. Likewise, if a large character is on several cells with the same effect, he is affected only once by this effect.

Certain skills allow you to push characters hit by a certain number of cells, either to push them back or to attract them. A jostled character moves in a straight line on the map until reaching the indicated number of cells or meeting an obstacle. The distance of the pushover is affected by the character's stability factor. For example, a character with a stability of 0.5 who is jostled by 10 cells will ultimately only be jostled by 5 cells.

Both characters and tiles can receive effects, either in their initial state or through a skill. An effect is an element which attaches to its target and causes various events according to its specificities. The effects can have an unlimited or temporary duration, in the second cell the temporality is determined in number of turns and disappears once the turns have passed.

Although a target can receive several different types of effects, identical effects do not stack. If a character or cell receives an effect that he or she already has, it will be reset and the new effect will not be added. There are also cumulative effects as stated in their respective descriptions.

A trap is a cell effect invisible to the opponent and which is triggered when a character, ally or enemy, walks on the latter's trigger zone.

A camouflaged character is invisible to the opposing player but is not immune to damage. It is quite possible to attempt an attack in the void to try to hit a stealthy character. A camouflaged character is temporarily revealed if he is hit by a skill. Likewise, if during a movement the moving character collides with a camouflaged character, the movement is interrupted and the camouflaged character is revealed for that turn. In addition, some skill reveals the user's position and some stealth skill ends when the stealth character launches an attack. A revealed character will return to the stealth state upon completion of the turn or after making a move.

There are several ways for a character to become camouflaged, whether through a skill or an effect. Tall grass for example has the effect of giving the camouflaged effect to characters of size category 1 entering the cell and removing this effect when the character leaves the cell.

Some skills allow you to summon characters. A summoned character can be immediately controlled by the player. Some summons are limited in number while others disappear after a certain number of turns. When a summoner dies, all of their summons die with them.

The characters that the player can control are active characters and are present in the list of characters that the player has on his team. Passive characters are characters without any abilities and who are not represented in the player's list, even if they are part of his team. In addition, certain effects take this difference into account, for example the crystals which give victory points only if the character in his zone is an active type character.

Some characters can go into an off-map state. When a character is in this state he is totally isolated and is in no way affected by what is happening on the map, even if the position is the same. Being off the map does not prevent the character from moving and even allows characters to be on the same cells. In addition, an off-map character is not visible to the opponent and his position cannot be revealed.

Some characters can have special properties that can vary how they work in the game. For example, there is the Always Visible property which prevents the character from being camouflaged or the Immobile property which prevents the character from being jostled or from gaining points. movement.

Lostria is a pure strategy game. Therefore, in order not to force the players to be careful not to miss a stealthy movement from one bush to another, a bar summarizing all the events of the game is at the bottom of the screen. Information on an event can be accessed by hovering over the associated icon. In addition, it is possible to obtain the location of the event by clicking on it.

Le récapitulatif ne donne aucune information supplémentaire à ce que le joueur peut voir par lui-même. La localisation d'un événement prend donc en compte que le personnage est camouflé et n'indiquera pas sa position. Dans le cas d'un déplacement, l'indicateur montrera la zone des positions possible.

Events from identical sources are cumulated in order to gain readability in the summary bar. For example a character who moves 2 cells, then 3 cells, then ink 2 cells, without any other intermediate action will be presented as a displacement of 7 cells. Another example would be the effects of boxes, like the Flaming Terrain which, at each change of turn, presents only one event which brings together all the affected characters.

During the transition between team building and confrontation, a screen presenting the players and their teams is displayed.On this screen players can see the ranking of each, their avatars and usernames as well as the composition of each team and the corresponding faction mastery level. In addition, a small random sentence presenting aspects of the universe of Lostria or game tips is present at the bottom of the screen.
