The Falador Mole Lair is a popular dungeon located beneath the Falador Park, home to the Giant Mole, a mid-level boss that’s both accessible and rewarding for players looking to start their PvM journey. This dungeon is straightforward in design but offers plenty of excitement for adventurers.

The Giant Mole drops valuable resources like mole skins and mole claws, which can be exchanged with Wyson the gardener in Falador Park for bird nests. These nests often contain valuable seeds, making this lair an excellent money-making spot for mid-level players.

Accessing the Mole Lair requires a spade to dig at one of the molehill locations in Falador Park. Players equipped with a light source and a Dwarven Cannon can increase their efficiency when hunting the Giant Mole, as the boss often burrows and relocates within the lair during combat.

For players seeking a relatively low-risk PvM encounter with decent rewards, the Falador Mole Lair is an ideal destination. It’s a great starting point for those new to bossing and offers consistent profits for minimal effort.

#12: Lumbridge Swamp Caves

The Lumbridge Swamp Caves is a dark, eerie dungeon located beneath the Lumbridge Swamp, offering a variety of content for low- to mid-level players. Packed with unique creatures, resources, and even a Slayer Master, this dungeon is a versatile spot for training and exploration.

Key inhabitants of the swamp caves include Cave Bugs, Cave Slimes, and Cave Crawlers, making it an excellent location for players working on Slayer tasks assigned by Mazchna or Vannaka. In addition, the caves provide access to Rockslugs, which require bagged salt to defeat, adding a fun mechanic for Slayer enthusiasts.

Players must bring a light source to safely explore the caves, as the darkness can deal damage if left unlit. However, caution is advised—open flames like lanterns may explode if gas pockets are encountered, making a Bullseye Lantern or Kandarin Headgear the safest choices.

For skilling, the caves also contain waterfiends, providing decent combat XP and occasional rune drops, as well as Swamp Toads in the above swamp, which are useful for Herblore.

What makes this dungeon particularly appealing is its accessibility and simplicity. Located just northwest of the Shantay Pass, it’s easy to reach for players completing Slayer tasks in the desert. The monsters within the cave are weak to Crush attacks, and their high numbers allow for quick task completions with minimal downtime.

For those looking to maximize efficiency, using cannons in the cave can dramatically speed up Slayer tasks, as Kalphites tend to gather in clusters, making them ideal targets for area-of-effect attacks. The cave also offers safespotting opportunities for players with lower combat levels.

While the Kalphite Queen resides in a separate cave, the Kalphite Cave is an excellent training ground for Slayer and combat experience, providing decent drops like Herbs, Runes, and occasional valuable items.

Revenants scale in difficulty, from low-level Revenant Imps to the formidable Revenant Dragons, making the caves accessible to players of various combat levels. However, their powerful attacks and the danger of player-killers (PKers) patrolling the Wilderness make this a challenging and risky area to explore.

The loot from Revenants is what draws players to these caves. Notable drops include Ancient Crystal shards, Bracelet of Ethereum charges, and high-tier weapons like the Craw’s Bow, Viggora’s Chainmace, and Thammaron’s Sceptre. These items can be incredibly profitable, but farming them requires caution and preparation due to the constant threat of PvP encounters.

To maximize survival, players are encouraged to bring minimal risk gear, utilize escape routes, and keep teleportation options like a Royal Seed Pod or Amulet of Glory handy. The Revenant Caves also have multiple entrances, allowing strategic access points to minimize PKer encounters.
