|Notes:||This spell is an upgrade of Fire Field. On PvP worlds, this spell is useful for trapping players during battle, though it allows for low-level characters to suicide and give unjusts to unsuspecting combatants. The first stage of the fire field lasts 3:20; the second stage lasts for 2:28; the last stage (that does not block a monster) lasts 1:38. Total time that a fire field will block a monster is 5:48. One of the best ways to trap and kill afk botters is to shoot the firebomb directly at them, then they can't move for almost 6 minutes. Also good if you are a lower level than the botter and to test if he has attack player on.|
