We’ll begin by looking at the characteristics of a forest. We will use a Small Forest (14” x 14”, Con 80, Density 3) as described in 3.3.4. According to 3.3.3.3.2 Terrain Wounds, this forest has 14 x 14 x 3 = 588 wounds.
Our unit of 5 dyndraig maneuvers into position where they’re able to hit the forest with their Fire of Gwaelod breath attack. Referring to 6.34.3.2 Spraying Terrain, the unit will have a total of 5 shoot dice needing 2s to hit (skill 28 vs 0, easy shots). The forest will evade using its constitution of 80, requiring 3s to avoid taking damage. Probability says that the dyndraig probably only do a single point of damage per turn using their fire breath, with a 5% chance of the forest actually catching fire.
Unless I’m missing something, it’s not really worthwhile to try to burn down the forest.
Some thoughts I had on how to make this more effective:
- provide some sort of multiplier for spray attacks against terrain (use density?) to increase the chance of a fated hit to cause continuous damage
- adjust the modifiers to the evade roll. Trees do a better job of avoiding damage than an unconscious warrior
