Place a fire trap that explodes when an enemy approaches, causing [RAP * 0.1 + X] to [RAP * 0.1 + Y] Fire damage and burning all enemies for Z additional Fire damage over 20 sec to all within 10 yards. Trap will exist for 1 min. Only one trap can be active at a time.
Explosive Trap is the only trap that can deal damage to more than one mob.
Against mobs that split into smaller mobs, such as the Razzashi Broodwidow in Zul'Gurub, drop this trap in the middle of the group to deal lots of damage. [Feign Death] afterward if necessary.
Limitations
Trap will exist for 1 min.
Traps can now be placed while in combat; however it will not become active until 2 seconds have passed.
Only one trap can be active at a time.
Can be resisted.
Some units are immune to this trap.
It may strike neutral targets, causing them to aggro you.
[Entrapment] (SurvivalTalent): Gives your Immolation Trap, Frost Trap, and Explosive Trap a 5% chance per rank (5 total ranks) to entrap the target, preventing them from moving for 5 sec.
[Clever Traps] (Survival Talent): Increases the duration of Freezing and Frost trap effects by 15%-30%, the damage of Immolation and Explosive trap effects by 15%, and the number of snakes summoned from Snake Traps by 15%-30%.
Resourcefulness (SurvivalTalent): Reduces the manacost of all traps and melee abilities by 20% per rank and reduces the cooldown of all traps by 2 sec per rank. (3 ranks total).
This is used in a few situations. Use it if you'd prefer a higher initial spike of damage with a short DoT rather than Immolation's long DoT. Another use is to pre-damage mobs when you have an unavoidable group pull. In groups, it is best used when faced with a large group of grey mobs. Almost always hit [Feign Death] after the trap is triggered. The textbook example for the proper use of this trap is Herod in the Scarlet Monastery. After he dies, several low-level mobs run into the room. They hit hard, but have glass jaws. An explosive trap combined with another group member's AoE is guaranteed to take them out before they hit anyone.
Explosive Trap trades with [Immolation Trap] for the best damage per second to a single target (depending on what level you are). Ultimately though, Immolation Trap will do the most damage per second to a single target but Explosive Trap will be better for multiple mobs. Even though this is true though, you will want to use [Immolation Trap] more often due to the horrendous mana cost of Explosive Trap.
Explosive Traps are also useful when fighting Elementals, as elementals generally have heavy armor and are immune to stings.
They are very useful in all aoe type situations and if you place them in front of the priest in a situation where healer aggro seems likely they will almost always divert mob/s going for the healer to you.
Explosive trap can give the hunter enough burst aggro to momentarily hold the aggro of multiple mobs off a warlock or mage doing heavier sustained AoE. Aspect of the monkey is a must in this scenario, coupled with [Deterrence]. Aspect Of Dragonhawk will work as well.
[Feign Death] afterward if necessary.
