In Carlin, at houses East Lane 1b or Harbour Lane 1 (Shop), there's a unique setup on the upper floor. When you ascend the stairs, you’ll find a square meter (sqm) that isn't a protection zone. With only one stack available, if you reach it first, no one else will be able to attack you.
To start, block the bottom of the stairs with Magic Wall or Wild Growth runes so that the Mad Sheep is summoned upstairs, in the sqm without a protection zone. Then, summon a Mad Sheep using a Spellwand until it breaks. You may need to use two or three Spellwands, as there’s a 75% chance of summoning a Mad Sheep upon each wand break. Keep in mind that summoning a Mad Sheep has a 12-hour cooldown.
Next, someone outside your guild needs to gain a white skull—this can be done by attacking you or someone else. If the player take skull you, they should use a Fire Field on themselves to maintain the white skull. Meanwhile, you should wait until your battle sign wears off. Once it does, attack the player with the white skull for you to gain a yellow skull. When you go up the stairs the Mad Sheep will continue attacking you, but it won’t inflict any damage. This keeps you in battle mode, so even if you exit or remain idle for 15 minutes, your character won't disconnect due to the battle status of the yellow skull (you can't enter protection zone).
After this, the player with white skull can hide to lose it, ideally someone with a lower level in case they are discovered and killed. At this point, neither the Mad Sheep nor you can be killed. As anyone who tries to climb up later won’t have the initial stack spot.
Now, it’s simply a matter of waiting for the cooldown timer of Gift of Life to reset. You can check the current cooldown by adding Gift of Life to an action button (right-click and select "Assign Passive Ability").

(Don't forget to use magic walls/wild growths downstairs so that the Mad Sheep is summoned upstairs, not downstairs as shown in the previous image)
