The Dust Devil is a sticky explosive weapon variant used by the Raider class in Tribes: Ascend. It can be unlocked for 160 Gold or 18000 XP.
"Modified for dry climates, the Dust Devil -as it's popularly called- is a special variant on the stock Arx Buster." In-Game Description.
Operation
Like the standard Arx Buster, the Dust Devil variant fires three sticky projectiles in quick succession. These rounds travel in a low arc and explode on a timer after 0.75 seconds. Although this variant deals less damage per round, the sticky grenades it fires detonate in a much larger radius, allowing the Raider to cover more area with the same amount of ammo.
Tactics
The Dust Devil should be used similarily to the Arx Buster, wreaking havoc inside the enemy base. While the Arx Buster is made for destroying base defenses and generators as it deals more damage per hit (600) and has a smaller radius, the Dust Devil is more focused in killing enemy players. The Dust Devil focuses on carpeting an area with explosives to kill enemies. The Dust Devil is not quite as effective against base assets dealing 500 damage per direct hit. Overall use this weapon for killing enemies, and the Arx Buster for destroying defences.
