Heroes 5.5 WarGame Edition - Tactical Edition.

There are triggers for AttackerBuildingDeath / DefenderBuildingDeath, and crystals, walls of swords, and hives should, in theory, be considered buildings. But even in this case, it's unclear how to track the Earthquake itself (and not just that the crystal exploded due to other reasons). In general, as I understand it, you can track the start of the battle (before and after deployment), the movement of units (written for AI control, needs to be checked), and the death of stacks. You can assign actions to units (playing an animation, giving the "Defend" order, shooting, casting a spell, using any activated ability, setting mana). You can speed up or slow down the turn of units (although they say they haven't figured out how the numerical parameter works), kill any stack, or create any stack. You can set or reset automatic control mode (for example, emulate uncontrolled berserker movements in this way). You can teleport units, force them to move, or attack. Basically, that's it – not that much.
