Since you are technically a "streamer" you can invite a "party" and have them participate as guests; With that you could make some raise their level and contribute applied knowledge.
It would be fun if you could introduce Kuroneko (Gokou Ruri) and that she could give you information about Terraria since this game started in 2011 and through an exchange give her power
Also when you go to the world of RWBY you can completely seduce Ruby Rose/Yang Xiao-Long/Blake Belladonna and be able to mark them so that they can be enhanced and then you update their weapons with materials
You must take advantage and activate the RWBY world mission and then acquire the Aura and Semblance to later be able to grant it when you visit other worlds
