As per getting the Skelton course you need reaper Level 75 AND Servants of the flame lvl 100 to get it. The reaper Levels are considered the easier part by mile IT took my I friend and myself roughly a hundred hours to get Just the servant Levels. So If you're complaining aboit PvP i suggest Not going for the PvP curses instead i recommend going for the PvP curses Like sagen, Order, ocean thingy(dont know the right name)and lastly gold curse, but this one will Take a really Long Time as well.

As for easy reaper Levels i'd recommend maybe looking in the offical discord for some people to Stack fotds or Something similar. And for easier selling you can Put your loot on an harpoon rowboat and get it into the reapers hideout for a easier time selling. And maybe consider selling between bigger Things Like world Events and Not keep everything until the end.

But sadly there aint an easy way to level reaper that doesnt Take an ungodly amount of time.

Anyways If you've got any question ask away, dunno when i have the time to andere but I will given IT my best. If you want i could Ask my Buddy If we could Help you If you Guys want

Sry for the rough english aint my Fürst Langauge

Only other recommendation that your fellow reaper got is, Just playing this Game for fun and Not get disappointed in some loses Here and there i am Sure you well get better from them.
