Hand Kite Mechanist is a good option to deal with Hands at the Deimos encounter while providing boons to the group. This build is easy to gear, as it is almost identical to Heal Alacrity Mechanist.
Your Jade Mech applies Might and Alacrity while you are away from the group. While this build uses healing gear, it does not have the ability to heal the group without compromising its own safety.
