Throwing these volatile flasks after setting the fuse ablaze will result in a fire field that either blocks the enemy's advance, or burns outright. However, the weapon is somewhat unreliable, and should not be used for regular combat.
The exact strength of flaming oil can't be measured, because of the fire-effect.
The use of flasks of Flame Oil constitutes an innovation in Britannia. Any of the Eight Great Professions can use it. The wielder casts the ignited oil in a chosen direction, creating a corridor of flaming oil which lasts several minutes. Any enemy entering the field of flaming oil suffers burn damage for each turn passed in the inferno. A favorite weapon among those badly hurt and in need of rescue - a last ditch defense.
Popular throwing weapons include daggers, spears, axes, and flasks of flaming oil.
Lightweight, hand-held items such as daggers, spears, axes or flasks of flaming oil can be most effective in times of need.
- In Ultima IV, enemies killed with flaming oil did not grant Experience Points.
