What happens to a unit when it has the Deathknell effect?

The Deathknell effect is a mechanic that specifically triggers an ability when a unit dies. This effect emphasizes the thematic elements of loss and consequence in gameplay, often granting a critical advantage or summoning another entity upon the unit’s demise.

When a unit with the Deathknell effect is destroyed, it can unleash powerful abilities, such as summoning additional units, enhancing stats, or triggering other beneficial effects according to the specific rules of the game. This makes the strategy around using such units particularly compelling, as players may seek to leverage the potential power gain from their units being eliminated.

In contrast, gaining health, reinforced defenses, or allowing for an extra turn do not align with the nature of the Deathknell effect, which is uniquely tied to the unit’s death and subsequent triggering of an effect, rather than enhancing the unit's functionality or survivability.
