The Nanotech is a post-Moon Lord Accessory for the Rogue class. When equipped, rogue projectiles release a nanoblade while active for every half a second, up to a maximum of five blades at once. Nanoblades deal 60 typeless damage which can be affected by rogue damage bonuses and can slightly home into enemies. The accessory grants the effects of the Raider's Talisman and Electrician's Glove. It also grants +15% increased rogue damage and 15% increased rogue velocity.

If the player utilizes a stealth strike and hits an enemy with this accessory equipped, three nano flares will rain down onto the target. Nano flares deal 120 typeless damage which can be affected by rogue damage bonuses. This effect only triggers for the first three enemies hit, and has a cooldown of one second.


For a full crafting tree, see here.



  • Effect can only occur when striking an enemy that has a damage stat of 5 or higher, that are not spawned from statues.
  • The projectiles created by weapons like the Scarlet Devil and Gacruxian Mollusk also leave nanoblades in their wake.
  • This accessory can be considered the counterpart to the Eclipse Mirror, as that focuses more on the stealth aspect of the rogue class, whereas this accessory focuses more on the damage aspect.
