Howling Cave

The Howling Cave is a semi-secret cavern located behind a waterfall in the Birch Park. It requires Superboom TNT to enter, which can be bought for 2,500 coins from Walter in the Gunpowder Mines, or can be bought for 3,000 coins from Ophelia at one of the two Dungeons entrances.

It is located at in The Park, in the Birch section behind a waterfall.

The NPC Old Shaman Nyko resides in the end of the cave. He is a merchant and sells a True Defense enchanted book, and a brewing ingredient named True Essence, which is useful when fighting Sven Packmaster because it deals True Damage.

The enemies inside include the Pack Spirits, which range from 6,000 to 7,000 HP, and the more powerful Soul of the Alpha, which has 31,000 HP. They all deal True Damage. For this reason, it is only advised that high-level players enter, otherwise they will most likely be killed by the hard enemies.

The Pack Spirits and Alphas drop various types of logs (e.x. Jungle Wood, Birch Wood, Spruce Wood) and Bones.

The Soul of the Alpha has a 1/200 (0.5%) chance to drop a Weak Wolf Catalyst, used to craft a Wolf Ring.

There is a Fairy Soul here, obtainable by swimming up a 1x1 block water column near the back of the cave.

Trivia

 * If a player uses Superboom TNT to open the passage, all present players from either side of the wall are able to pass.
 * This is an excellent place to create a Sven Packmaster, as the enemies here are high-level, requiring fewer kills to summon. The numerous pits and spikes offer places to climb upon or run to, which can slow down Sven from attacking you.
 * If a player has a Horse Pet or Pig Pet, they could stand against the wall and spawn it in the wall, ride it and go straight forward they could glitch through the wall to get through without using Superboom TNT.
