Huh, I'm still a noob at your side xD
Of course i'm still working at that (focusing on my heat since yesterday xD)
I think i'm doing it well since i have 6-7 days (with my old account, so i was in lvl 30 and equiped with legacy items)... but not sure
(Physic mech) did nothing in particular... Just sitting around and waiting for better weapons and modules (and hoping that they will change the fusing system to recover the power from that torso)
(Heat mech) Today fused my Nightmare torso and Corrup Light to legend, changed Ironbark with
that BackHammer and Terror Cry (because both only weigh 1kg more than Ironbark...), to make combos and put the enemy withing the range of the Corrupt Light, then will fuse Scorching feet and the other Corrupt Light and so on...
