Hey there great to see you are trying new bots/skills ^^ Okay so for GE that's a good idea we had that request I have laid the groundwork will be adding more options including falador, varrock (east & west) firemaking, and in the future I'll be adding clue hunter outfit gathering, maybe even chopping for logs (HCIM/IM only) for firemaking, and that's about it not sure what else would be missing at that point
So for running backwards my best guess is the bot is going back to safezone where it won't get attacked anymore, now depending on your stats I would usually select [Switch to chop burn] under the setting [After 500 points...] so that you can get more xp/hr and potentially better rewards from the game. Otherwise the bot will just retreat back and wait. Another thing is that it could be going to bank due to no food, what's your food settings? I usually set it to Cake, withdraw 6, and bank when less than 3. I have a feeling you already set this up correctly but just worth mentioning. Either way I will go and take a look just to make sure. I recently ran this bot on my main for 70 firemaking yesterday and Saradomin Brew (4) from level 50, will keep going and see if I can improve anything
For percent I would base it off wc level, if you feel that you can easily achieve 500 points then I'd set it to lower (no lower than 80), but the default 90 should be enough. That setting basically tells the bot: don't participate in this game because the boss's health is less than 90%, wait until the next game.
As for banking I've noticed it sometimes clicks behind the bank especially during lag, I'll see what I can do about this should be an easy patch,
Again thanks for letting me know + for all the feedback
