Siege Archer

The Siege Archer is a promotion of the Archer. Like the Archer, her passive ability is Puncture.

Ability: Slag and Burn
The Siege Archer targets a tile (not a unit), occupied or not, in her normal attack range of 2-5 tiles. She slags the target-tile and its four adjacent ones and then fires a flaming arrow igniting the 5-tile area and causing an explosion. All units in the 5-tile area, enemies or allies, receive strength damage while the unit occupying the target-tile receives additional armor damage.

After the explosion, burning coals are randomly left on unoccupied tiles of the slagged area. When targeting an unoccupied tile, coals always appear on that central tile. Units who walk over the burning coals take 1 strength damage. The coals burn until the Siege Archer's next turn or until she's killed.

Rank 1: 1 armor damage (target unit), 1 strength damage (all units), leaves up to 2 coals

Rank 2: 2 armor damage (target unit), 1 strength damage (all units), leaves  up to 3 coals

Rank 3: 3 armor damage (target unit), 1 strength damage (all units), leaves  up to 4 coals
