Special properties of units and heroes.

1). Tactics – stacks of creatures with this ability can split and merge directly during combat (a variation of "tactics" is the "scatter" ability, where a stack can instantly split into individual units during combat if the battlefield allows it);

2). Self-replication – a stack creates an exact copy of itself, which disappears from any attack on it or after 2 turns after appearing;

3). Piercing scream – when taking damage, the stack emits a very loud cry of pain, inflicting damage within a certain radius to both enemies and allies, and giving a 2-3 turn stun chance;

4). "Infection" – when attacking, a stack has a chance to turn the enemy stack into copies of itself until the end of the battle; after the battle, the effect is removed;

5). Corruption – a stack targeted by corruption has a chance to completely disappear after 3-4 turns (let this be a type of magic, so it doesn't affect immune units and can be dispelled);

6). Evil eye:D (since corruption exists...) – a stack affected by the evil eye receives a 20% chance to miss in both melee and ranged combat.
