Lightning Ball is an arcane offensive spell in ADOM. It allows the caster summon an lightning storm around himself/herself, damaging all beings in the area.

Lightning Ball is the second most expensive (and powerful) ball spell in the game (not counting Improved Fireball), thus sharing the following common features:

  • Effective range is approximately a circle (counting in tiles) with the radius based on PC's Willpower
  • Attacking monsters with Lightning Ball while invisible will betray the PC's location to them
  • Lightning Ball will damage everything in its effective area including monsters in walls and outside the PC's line of sight

Lightning Ball is very effective against humanoid constructs (most notably steel golems) inflicting increased damage. This allows for a great albeit very risky way of clearing Darkforge even for low-level spellcasters.

Stats[]

Damage

Lightning Ball damage is dependent mainly on PC's level (L) and slightly on spell proficiency (P). The exact formula is the following:

max{3, [2 + L / 4]}d8 + L + P

Radius

Lightning Ball radius is solely dependent on PC's Willpower (W). The exact formula is the following:

max{2, [W / 8]}

Only every even value signifies a different blast size. Radius value should be divided by 2 and rounded down — the resulting number corresponds to actual circle radius counting in level tiles. In practice, the observable increase in spell radius will first occur when the PC reaches Willpower score of 32. Every 16 more points of Willpower (48, 64, etc.) will trigger another increase.
