Title:
Improve party play for Constellation Tower instance.
Description:
As of now, lots of people prefer to farm CT alone with their double logins, but what if there was an incentive to play it with others?
Instead of making the current meta worse, i propose giving a fixed reward per single master account when completing the instance, based of the amount of master accounts in the party (and in the map).
Exemple:
1 Master Account: Current reward.

2-3 Master Accounts:

4+ Master Accounts:

This would help not only improve party play for this instance but also bypass some of the RNG rewards that can sometimes be frustrating.
I'm not proposing any exact number since it already scales with difficulty, but the idea should be give some extra materials per master account when claiming rewards talking to Betel.
Why is this a good idea?
Getting extra rewards for playing an online game with other people seems a good idea to me!
What risks or downsides does it have?
More CT materials maybe would lower the price, but that's all the cons i can think of, since people who run the instance would still be able to decide to keep on doing so alone and getting the same as of now, or share with others for a bit of an increased reward.
Additional Info:
Chest rewards would be untouched.
