Veteran players are likely to already have the 3 current Costume hats (Spookat, Frankenzom, Phantom), in which those who have all 3 of them end up having to choose to focus on only the Hallow Boxes or ignore the event altogether. New players can sometimes easily obtain all the items in 1 event as well, given their friends would likely provide the player extra chances to meet Pumkin King even when they struggle to find him.
I was wondering if it's possible to create 2 new types of costumes that use 2 new variants of candies. Each requires the same amount of their respective candies to collect to obtain them:
1) Gorgo Mask - Paper, Replica, and Authentic Variants - Requires Bitter Candies
2) Bombie Mask - Paper, Replica, and Authentic Variants - Requires Spicy Candies
By doing so, it could make veteran players have more options of costumes to obtain, while giving new players an incentive to team up with and make more friends so the player can obtain enough candies for their desired masks. With more candy varieties (and dropping randomly within current PK candy drop limits per encounter depending on tier), obtaining them all may result to multiple Dark Harvest events in order to collect them all (depending on the amount of time the player has to play Spiral Knights).
Hope you like the idea.
Then they should change Hard Candies into Salties :D +1
