This celestial booster build is great offensive support made for open-world and is beginner friendly. The equipment above is designed to be played with no modifications from the exotic gear obtained by the level 80 booster. If one does not have the level 80 booster available to them then the equipment can be obtained through crafting or purchasing directly from the trading post. This build utilizes the elite specialization of mechanist. Specifically, this build will allow you to provide permanent Alacrity, Might, and Stability uptime and some Barrier. Being a pet build makes it very strong as it allows your mech to tank for you.
While applying boons with mechanist is easy, one should remember that the boons are around the mech. The mech must be nearby you and your allies to provide the best support. Shift Signet teleports you and your mech, removes conditions and breaks stun. Overclock Signet allows you to recall your mech should it become destroyed.
Dealing damage with this build is done by combining rifle skills with a grenade kit. Use all your rifle skills off cooldown. Blunderbuss and Shrapnel Grenade share the same cooldown and you want to use them together.
