The recursive bullet effectively functions like a machine gun. Upon being called upon via portal, the recursive bullet drains some of the user's aetus in order to accelerate itself to the speed of a bullet. Once that has happened, upon striking a target aetus will flow past the insulator and into the portal mechanism, opening a portal back to https://scratch.mit.edu/projects/737732767/ to come right out of the portal it was summoned through once again, though the portal mechanism can be detonated early via aetus puppeteering (controlling aetus that has recently exited one's flow). 6 Recursive bullets currently exist in this iteration of the space, so that multiple can be in the portal loop at once.
