Back in the good ol' PVE days (and probably still now), I remember assassin golden son was one of the most favorable attacker. Comes as a 3 star, does a decent damage, and cheap to be maxed (takes only 4 skill shards).
However, I found that assassin corrupt droid is more interesting than the golden son. Both comes as a 3 star, both does a decent damage (albeit it's physical & magic damage instead of true damage). The difference is, corrupt droid has abilities to heal (both skills) and grants void shield, whereas the chance of golden son healing is only with vampiric talisman, oh, and he grants endure.
Corrupt droid needs 6 skill shards to be maxed, just 2 more than the golden son. I still need one more to max him for his basic skill. Yet, he's on my PVE farming team most of the time now.
Any thoughts about this robot?
