A specific epic variant of the Deconstructor is available for purchase at level 36 from Dome City's Recon Gear vendor for 7,500 Conquest Tokens. It is extremely useful in all levels of PvE, and in Sonoran desert raids. It is mandatory in ddr and lacking one can get you kicked from most professional teams.
When deployed the decon becomes permanent unless it is hit by enemy fire, the recons own bombs hit the decon, or the recon moves too far from the decon. It is placed in PvE on the spawners that spawn minions in the boss fight as well as during the mission on the alarm responeders spawners or to burn the boss. Decons are useful in SR to kill adds coming in from certain loctions and to help "burn" the boss. Decons are used in ddr to kill ticks and in segments were there are no ticks to help kill adds. In PvP the decon is used to destroy robo-nest quickly.
