WvW Core Swap
As the old saying goes, “You never truly know your enemy until you’ve defeated them and stolen their profession’s skills.” You can finally put this wisdom into practice in your everyday life during the WvW Core Swap Special Event!
From July 5 to July 12, defeating an enemy player in World vs. World will spawn a glowing orb over their corpse for a short time. Claiming the orb will grant you some knowledge of your enemy’s profession. You’ll retain your own weapon skills and gain access to a special skill that allows you to use the healing, utility, and elite skills of the defeated player’s profession.
The healing, utility, and elite skills you can obtain are the same for every enemy of a given profession, and cooldowns persist when you swap to and from the purloined skill set. For example, when you defeat a thief, you’ll have access to the following skills:
- Scorpion Wire
- Blinding Powder
- Skale Venom
- Thieves Guild
In addition to these wonderful toys, you’ll also gain double WXP, 25% extra WvW reward track progress, and 50%+  Magic Find in WvW for the duration of the event. Head over to our official forums to discuss the event and prepare for the mayhem!
- Call of War: Earn increased rewards in WvW.
- Defeating an enemy player character will spawn a Knowledge Orb of their profession on their corpse for a short duration. Moving your character over the orb will pick it up automatically.
- A Knowledge Orb grants special action skill to use a pre-determined set of healing, utility, and elite skills from the defeated enemy of a given profession, as listed below.
- Using the special action key a second time will Release the spirit, and remove access to the Knowledge Orb, therefore allowing the player to pick up a new one.
- The Spirit of ... special action remains until used, then the alternate skills remain until Release ... is used. To go back to the same or other alternate skills, you need to pick up another Knowledge Orb.
- Knowledge Orbs persist through death.

- Revenant Knowledge Orbs grant modified versions of their skills.
