so my experience with this has not been great.
in no particular order, here are my chief complaints about this macro. some of these probably could be resolved with a better mesh, but I dont know how to do that.
1. Frequently my lev'd toons will get stuck above the slime after I say defy her and they all run down at once.. I often have to tab over to each toon, pause them and set them manual so I can reposition them to engage
2. randomly, toons will get stuck in the upstairs spider room because they are trying to path over the balcony. sometimes they get stuck trying to path over the lava chute in the middle.
3. I've had inconsistant and infrequent failurs with soundproof. I've followed everyones advice, set barbarian campfire, lev on, and my sk tank is never called by the notes so I think he's agroing fast enough. I typically am watching the tank and looking for the fail message so I can kick the task...
4. when we win, the script runs all my toons to the LS zone entrance. you know, a mile away from the chest...
other than the above, the macro does get the win and occasionally i can get all 3 achieves.
I did however try this alternative
https://www.redguides.com/community/resources/heroes-are-forged-mission-script.2976/ and after 10 or so minutes setting up the LEM event, I ran it and got all 3 achieves on the first try. My poor chanter has been waiting so long to upgrade his neck!
