Hint 1 is the tower stack, with a 4du buff beam, you wanna split the towers up on the beam and have the owls on the south end of it because of where you will be placing your guardian characters in which one will have a squire guard, so you want the squire guard targetting the owls, more on that later
Also at hint 1, you will place your tower booster (and upgrader adept for the first wave) and aim it at hint 2
Start with tower booster main split and adept upgrader second split and remove adept upgrader once towers are maxed and run JUST a tower booster until w35, on w35 you can add whatever characters you want to target the weapons for with two huntress guardians and a squire guardian and place them at hint 3 below the ledge that you put your towers on, i use huntresses because i like the gun
I get around 10:30 total with 8:30 combat on avg with my stats, you may end up with faster or slower depending on yours
listed stats are just my stats, i imagine lower stats will work just fine
