Help with damage boosting

so, not sure if this is the right place to post this but ill go ahead and try. Me and some friends started this shared randomizer connecting a few different games and i chose Links Awakening. I dont have Rocs Feather so i cant jump but the nightmare key chest in tails cave should be accessible using a damage boost i have just never been able to properly set it up. i feel like it should be simple and i am just stupid but i cannot find any guide online. If i could get anyones help on how to set it up that would be amazing. Thank you
