Perks change the way you play in Call of Duty Black Ops 7 Zombies. The Wisp Tea perk is one of the best freebies on Vandorn Farm. The perk normally costs a lot of Essence, but a simple map sequence called the Ghastly Waltz can hand you Wisp Tea for free. Players who practice movement and timing in a CoD BO7 Bot Lobby will find the steps easier to learn, but you can also do this on a normal run if you know the order.

Step 1 The Haunted Broadcast — the farmhouse second floor
Start inside the main farmhouse and go to the second floor. The old TV there is the first trigger. Stand by the TV and interact with it until the screen image changes. Keep pressing the interact button until you see both ghostly twin figures appear on the screen at the same time. This is the first visual cue that the ritual has begun.

Step 2 Isolating the Twin — TV to cellar
After both twins show up, keep interacting with the TV until the image changes again. The screen should now show only one twin. Once you see the single figure, run down to the cellar right away. The cellar holds the ghost you must find. When you find the lone ghost, interact with it repeatedly until the spirit fades. The ghost must disappear for the sequence to continue.

Step 3 Clearing the Screen — return upstairs
Go back up to the second-floor TV and check the screen. The image should have returned to both twins. Interact with the TV again until the screen clears of any ghostly images. This step confirms the ritual has completed the middle phase and sets up the final event outside.

Step 4 The Final Dance — outside the generator area
Head outside toward the area between the jump pad and the main power generator. The two ghost girls will appear there and perform a short, silent dance. Wait for them to finish their movement. After a few seconds, the ghosts will vanish and drop a free, ready-to-use Wisp Tea Perk bottle. Pick it up and you keep the perk without spending Essence.

Why the Wisp Tea perk is worth doing
Wisp Tea gives a strong early boost that changes how you spend Essence later. Saving Essence on this perk lets you buy Pack-a-Punch access, armor, or other map upgrades sooner. If you practice the steps in a CoD BO7 Bot Lobbies, you can repeat the run quickly and learn the timing without wasting high-round attempts. The free perk is especially useful on high-round runs where every point of Essence matters.

Tips and common pitfalls
Move fast between steps and avoid long delays. The sequence is strict and timing matters. If the TV image does not change, step back and try the interaction again; sometimes line-of-sight with the TV or a stray zombie can block the trigger. In the cellar, be sure you hit the exact ghost you saw on the TV; other spirits may spawn but only the matched ghost will clear the phase.
