Effects and formulas#
- The target first receives a spell-resistance check. On failure, poison strength uses the caster’s Magery + Poisoning (subject to duel skill rules).
- At distance 3 or more the poison is Lesser. Within 2 tiles: total > 200 has a 10% Lethal / 90% Deadly roll; otherwise > 199.8 gives Deadly, > 170.2 Greater, > 130.2 Regular, and the remainder Lesser.
- Between 2 and 3 tiles, subtract (distance − 2) × 31 from the combined skill before the thresholds. School conflict scales subsequent poison damage rather than changing the selected poison level.
Notes#
- Magery–Necromancy school conflict can reduce the effects identified as school-scaled. Listed mana and cast delay are base values; equipment and casting rules modify actual costs and timing.
