>>79957222She should've got her manager or someone in Cover to contact Jagex directly. Jagex will make custom worlds for independent content creators fairly often, if a big company like Cover approached them with an idea for a private world for the Hololive Girls to stream in, Jagex would've probably offered them payment for the marketing. The private world could've had some enhanced XP and drop rates so the girls didn't have to grind forever, making the streams more fun to watch, and it could've easily become the new Minecraft/Rust for the girls.
But I don't blame Nerissa. Chances are, just getting all of Advent to settle on a collab time probably exhausted her to the point of near death. It would've been great if the other girls/managers had seen the potential and had helped prep though. Pity FWMC were sick for the last half a month, otherwise they might've been able to help considering their experience with the game.
TL:DR
Kaela reaching 99 in all skills will forever just be a dream
