i use my SE mule marksman do the quest Jenn's Brother in LHC. i can not kill any one of them use the skill snipe(max) for 1 hour t0 kill 4 Red Crocky guards,
i just did this on my shad yesterday took me 7 minutes with stoppers at lvl 138. 127wa dagger, maybe 7b in gear. i remember on my bm like lvl 150 and maybe 2b in gear was like .....10 minutes with apple? not sure. but if it really took you 1 hour, seems like bug. i remember another archer says it took her long time on beccas thread. https://royals.ms/forum/threads/lhc-pre-quest-guide.207734/#post-1235931 edit: i see you said mule, so im wondering how bad your gear was
Red crocky has a pretty high hp recovery rate. I recommend you come back with a stronger attack power!
