So i've had some time to check out this script and honestly with it not being updated in almost 2 years it's pretty solid.
The ONLY issue i've personally found is when it's collecting tokens...
When the script uses enough food to trigger a bank, it will finish killing the current armor set then leave the tokens/armor on the ground and go bank, while at the bank it will grab a new armor set if you have it or stop script if you don't have extra sets.
Then the script will go back into the room and pickup the tokens on the ground.
This causes you to loose an armor set if your account doesnt eat enough food to make inventory space by the time it despawns.
Additionally when finishing the dragon defender the script just ends and if you're not babysitting it you'll die and lose your stuff.
Other than that it's solid.
