Kvk 1 infantry legendary equipment
Mid KVK1, running suntzu-ysg(5524). Equipments as shown in picture, i recently got enough of chests to unlock a legendary leg blueprint. However, i got two types of chest with same name but different choices which confuses me a lot.
The first chest can give me eternal empire but only 13 pieces. Second only gives eternal night but with first combined i can get a eternal night blueprint.
The question is, should i be going for eternal night? (I might not be able to craft it right away), Or, get eternal empire and wait for the remaining pieces? Thanks.
