Solo 9 Minute Intermediate mode Method (3K gold & 40k EXP per hour) | TDX
This is possible without juggernaut and John but you have to spam more towers down when you max out your your farms at level 4.
If you dont own gamepasses its obviously slower at around 14 minutes per run, iv been using this the past couple of days which is why i have like 80 intermediate wins in game.
