This is a list of skill points in Ratchet & Clank: Into the Nexus.
It could be achieved by using a Grav-Tether to transport an enemy over a gap, and then deactivating it to let them fall to their doom.
It could be achieved by destroying all of the tables, chairs, and pots in the first area on planet Yerek.
Guide: This skill point is fairly easy to obtain, just check the left and right sides of the fairly linear path for tables and chairs. You only need to destroy the objects up until the area where you receive the Grav-Tether.
Keep on Moving
Assassin of Leisure
Eye for an Eye
The skill point is based on an old legal principle in which a criminal is punished the same way the victim of the criminal was treated, sometimes in a literal sense (such as having one's arm cut off after cutting another person's arm). In the Eye for an Eye skill point, Ratchet retaliates against the Mr. Eye's Nether attacks by striking Mr. Eye with Nether based attacks (Nether based guns, like the Nether Blades and the Netherbeast).
