Hey,
Maybe add trimmed comp cape to a list of achievements to complete, i have a few suggestions on how to get it.
suggestion 1:
Lock it behind 5b xp, simple and straight forward to only need this. The grind will be bound to all skills etc.
Suggestion 2:
Lock it behind a certain amount of achievements in the achievement tab. Maybe even all of them, this also adds a bit of a new grind to the table as the achievements does not give rewards yet.
Suggestion 3:
Lock it behind 5b xp AND achievements to make the grind even bigger.
Suggestion 4:
Lock it behind just getting alot of more KC like in the comp req but require it to kill Harb and other hard bosses with like 50-100 kc aswell as double all the kc for regular comp.
