What role does a unit with the Deathknell effect play in gameplay?

A unit with the Deathknell effect plays a significant role in gameplay by triggering additional effects upon dying. When such a unit is defeated, it typically initiates a chain reaction that can benefit the player in various ways, such as summoning new units, empowering existing ones, or dealing damage to the opponent. This ability to create advantageous situations upon death adds a strategic layer to gameplay, as players may intentionally place these units in positions where they can be sacrificed effectively for greater benefit or use them as tactical tools to shift the tide of battle.

In contrast, while gaining Might upon death might seem beneficial, this is distinct from the primary intent of the Deathknell effect, which focuses on triggering effects rather than enhancing characteristics. Similarly, while extra actions can certainly alter the pace of gameplay, this is separate from the specific mechanics of a unit with the Deathknell effect. Lastly, the role of a sacrifice is more about the intent behind the unit's use, which may happen in relation to the Deathknell effect, but the core function of such units is to activate specialized effects upon their demise.
