Hello guys , 

I just want to ask if its possible to make a custom quest using the existing python methods.

Also i want to know if i can edit scroll of escape for the quest.

Example : If i get a specific item from a raidboss to teleport me in a custom specific location and i dont have the item to not teleport at all..

I want to know if its possible 

Yes it is possible. Since you mentioned python you probably using frozen. So, learn python and start coding :D

You can also copy an existed quest and remake it as you want with the npc rewards etc you like.. 

It's easy to modify a quest at frozen
