Attack Strength
Also called "Attack Roll" in some places.
Defense Strength
Also called "Defense Roll" in some places.
The target's block, effective dodge, and cover are added together to give Defense Strength.
Block
Block is straightforward. Just add Block to Defense Strength.
Dodge
The defender's Dodge is modified by the attacker's weapon Wield. Heavy weapons (low wield) are easier to dodge; light weapons (high wield) are harder.
Multiply by the following to get effective Dodge:
| Wield | Weight | Modifier |
|---|---|---|
| 1 | Ultraheavy | 135% |
| 2 | Heavy | 115% |
| 3 | Balanced | 100% |
| 4 | Light | 85% |
| 5 | Ultralight | 65% |
Cover
Partial cover is worth up to +30 Defense Strength; Good cover is worth up to +60. It is reduced if the attacker is firing from an angle, and they can "lean" to further improve their shot.
Specifically, the attacker consider five possible firing positions: the center of their current tile and positions offset by 0.7 to the north, south, east and west.
- For each of these positions that are not obstructed, check five lines to the target (or to each of the target's tiles, if it is large): from the firing position to the midpoint of the tile and to just inside the midpoint of each edge—technically, to offsets (0,0), (-0.49,0), (0.49,0), (0,-0.49), and (0,0.49).
- For each of these lines that is obstructed by any part of the cover tile, add 20% of the maximum cover value to that shot option.
The attacker then picks their best shot at the most exposed (lowest cover) part of the target.
