Cannons at green dragons are not supported yet but that is a good idea. Are you talking about green dragons in wilderness or corsair cove dungeon? I can add cannon support for green dragons but in the wildy locations it can be very complex to code a system for anti-pk with cannon, although I am working on it
As for crabs, activated trial you can test it, seems to be working for me now . Ammonite crabs aren't supported just yet but they are the next item on my to-do list for the script.
Thanks, I enjoy coding the fighter script more than all my other scripts except maybe the runecrafter, really fun to code.
