X-Men – Destiny: Triggering X-mode
Here’s what you need to do: match up all of the four items you have for the same character. For example: wolverine utility, wolverine offense, wolverine defense, and wolverine suit. After you have a complete set and matched up all items, you can then use X-mode. Important: you cannot mix and match x-genes and then use a suit’s x-mode. Mixing and matching x-genes cancels the x-mode.
