Firebomb
Campaign: Eye of the North Profession: Monster Attribute: Unlinked Type: Skill
¼ 3

Full: Launch a slow-moving firebomb at this foe. This skill cannot recharge slower than normal.

Concise: Launch a slow-moving firebomb at this foe. This skill cannot recharge slower than normal.

Notes

• After a few seconds the firebomb ends, creating a Firebomb Explosion at its location.
• Firebomb is a skill used by Ilsundur, Lord of Fire, the boss of the dungeon Catacombs of Kathandrax.
• It appears Ilsundur doesn't use this himself, but rather throws it at the target.
• The fire bomb can apparently be caught rather than picked up, thereby disabling weapon specific attacks (such as a warriors sword/axe/hammer attacks).

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. If you play in Non-PvP worlds, you can use the Fire Bomb like Destroy field runes, because the fields disappear in 3 seconds and clean the fields that were there before. 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.
