The Renown heart ‘Help Doolsileep protect Moogooloo village’ is right next to the Tower of Nightmares, causing much of the area that has the enemies that count towards the task to turn toxic. One step too far one way, and I’m out of the renown heart range (though enemies can still be found), but one step too far another way, and I’m dead in seconds due to the toxic shroud around the ToN.
Possibly increasing the range for the Renown heart could help fix, or is there some other area where we are expected to complete the task? I have usually completed the task in the area around the Auld Red Wharf, but that area is toxic now.
