What level do I need to go RG? it is necessary to do the lhc prequest I m already lvl 176 being mm I'm new to this LHC thing
Prequest guide: https://royals.ms/forum/threads/lhc-lkc-pre-quest-guide.207734/ I believe you have to do everything up to and including "Is there any hope?". Rose garden guide: https://royals.ms/forum/threads/rose-garden-guide.222052/ I will leave it to a pro MM to give you tips.
to actually enter you need to be 175 and do most of the LHC prequest (technically its VL prequest). as for how efficient it would be for you to RG, I am not sure what level would be good and that also depend on what other content you got. I dont have a MM so I have no idea how good they are there.
The second page of this thread does include some RG tips for MM: https://royals.ms/forum/threads/posts-marksman-guide-2023.214703/page-2 You want to level up Dragon’s Breath to 23 so you can push up to 6 mobs so you gather mobs faster. (lvl1 push 3 iirc) Use Frostprey in the boss fight so the mini golem won't bother you, and properly use a puppet to trick the boss so KCG can only case falling rocks attacks. The bonus stage trick mentioned in that article means you want to gather the second and third platforms to shoot 5-6 targets at once. To achieve this you want to learn Pierce Arrow jump shot timing. Aim at the bottom of the third platform first you'll get the trick. It's worth mentioning that Dragon’s Breath can also utilize jump shot as well, just press jump and Dragon’s Breath at the same time plus the arrow key.
I already did half of the lhc missions I just need more damage since the bosses are very tough and I spent 4 gelt (2 each) I still need the elite mobs I will take your advice it would help me a lot
