Coming back to RS with 150K loyalty points - what auras to buy? And is invention helpful for bossing?

Hey guys, so I quit for 6 months after losing 3B at duel arena. - Yes i went through a 'IDGAF' moment which is pretty grim.

Anyway, I'm deciding to comeback for the release of Telos, the new solo boss, now I know we don't know specifics about its mechanics however what auras would you pressume be OP against this boss? Got vampy, got the prayer version of vamp forgot it's name (facepalm), any suggestions with maybe a small explanation as to why will be sooo helpful!

Also, I knew about Invention whilst quit as I would check back every now and again on here but does invention have a big impact on bossing now? Would i benefit a lot from augmenting t90's? I do not have a clue about invention so any advice related between invention and bossing is also helpful!

Thanks guys, muchly appreciated<3
