Combat Positioning and Attack Rules (Thematic)

Scope

Use this skill for line-of-fire disputes, adjacency triggers, cover math, and attack/damage adjudication.

Attack core

• Attacker and defender roll opposed d20 + modifiers.
• Defaults: weapon attacks use attacker skill vs defender agility; many abilities use intelligence vs willpower.
• Hit if attacker total exceeds defender total.

Damage pipeline

1. Roll damage dice (with exploding dice rule).
2. Add melee strength bonus where applicable.
3. Subtract toughness (unless ignored by effect text).
4. Apply to temporary health first, then current health.

Positional pressure rules

• Threatened: in melee range of enemy.
• Major movement can trigger opportunity actions when leaving threatened adjacency.
• Ranged attacks can trigger opportunity attacks from adjacent enemies.
• Missed ranged attacks may still hit adjacent creatures near intended target.

Terrain interaction

• Cover: defensive block value vs ranged attacks.
• Concealment: sight-obscuring defensive block value.
• Obstacles: full line-of-sight and/or movement blockers.
• Taking Cover doubles current terrain-cover value but constrains movement.

Tactical stances

• Firing Position: fixed facing, no movement, gains offensive bonus choices and improved defensive posture.
• Exposed Targets: targets with no cover or concealment allow attacker offensive bonus choice.
• Flanking: exact opposite-side adjacency grants advantage.
