There are 4 affinities in total and each is represented by a symbol.

Every Champion in your roster, and enemy you face in Raid Shadow Legends, has an affinity. Should be Iron Twins or Gear Ascension Dungeons instead. Read this Raid Shadow Legends Affinity Guide for all you need to know. Content is easy and you don't have to grind it often.

Unkillable team is already tightly tuned to 2 key UNM easily but is far from 1 key so putting anything into it would either be a huge negative (speed) or effectively do nothing. Basically same as spider but to a much lesser extent. Currently only able to farm hard mode stage 6 and want to get to stage 10 ASAP since every single champion needs a bunch of stats from Spider and farming anything less than the highest stage for the same energy cost feels like a waste. If I could get to the point of at least 1:1 turns that'd help a lot. Hydra is the area I'm most behind in by far and I think the biggest reason is because how quick they are relative to my current gear level.
