Here's what I do:
Obviously the script only truly activates after it gets inside the dungeon.
But I have an upgraded range/melee ring, so I use ring switch, with melee as my primary, and range as my secondary.
Make sure you have a really good 2h/maul/spear, and 125 arrows binded. If you're over level 50, then get a great platebody (a shadow silk hood is useless).
Next, I suggest you turn on the following settings (if I don't mention them, turn them off).
Food prep (for 80+ cooking tbh), Quick pray, Pray Doors, Summon Doors, Explorer, Runecraft
On Complexity - Complexity 6, Prestige, Rush settings ONLY IF YOU ARE GETTING PRESTIGE, Grab food.
Then click through. It should start.
Click on Options, go to Binding, in the "Destroy" box, type your platebody's name (with the (b) ). Don't put anything in the 'Bind' box. The reason I've done this is because when I don't do that, I have a Katagon platebody and it tries to update and doesn't work. Even though I don't want it to bind.
