When the Asgard games event patch was added earlier in the game, the Union feature from the mercenary relic had gone missing or either removed. Is this a bug or did the developers removed it from the game?
This is not a bug, some game mechanics have been revised and so far Union will not have additional attributes to improve.
I see. According to the people who have already upgraded Union training features and gained the BR boost from it said they still have the boost so I thought it was a bug just like the previous time when the artifact had the runes bug. Anyways, thank you for your help. ^^
