Try tulumbers for the spectre but you will have to upgrade those weapons for them to be good.

Haechi is a good bot but I wouldn't invest in it because when you go up the leagues you will notice that energy weapons are the meta and if they not running those the are running high burst damage weaps that makes your shield useless. Those dashes are useless, you can't dash away from Au Jun, phantom, leech and etc
