The final chapter of the Oh No! Skeletor! Tales questline, introduced to BTD6 with the v51 update (November 2025), is Skeletor Gathers Power. Despite being the longest and most resource-focused chapter, it is still very easy to complete once you follow a simple economic buildup. This mission revolves around generating enough income and reaching the required 333,333 Cash before Round 60. No Monkey Knowledge is necessary, and the strategy relies on straightforward tower upgrades and controlled farming.
How to Complete “Skeletor Gathers Power”
This mission is all about scaling your economy efficiently while supporting Skeletor’s growing strength. Watch the video above to see all placements, upgrades, timings, and the full path to reaching 333,333 Cash smoothly. Here’s the full optimized approach:
- Start by building five Banana Farms, each upgraded to 2-0-0. While placing your Farms, add a Mermonkey to support Skeletor.
- Upgrade the Mermonkey to 3-0-2 to strengthen your early defense.
- Upgrade three of your Farms along Path 3 to 2-0-3 for faster income.
- Before Round 15, upgrade the Mermonkey to 4-0-2 (Abyssal Warrior) to easily destroy incoming MOABs.
- Upgrade your remaining two Farms to 2-0-3, bringing the total to five 2-0-3 Banana Farms.
- Place a Wizard Monkey and upgrade it to 0-2-4 for strong mid-game support.
- Add four more Banana Farms (2-0-3) to boost your income generation even further.
- To maximize money, place a 0-2-4 Alchemist near the entrance.
- Place a Monkey Village and upgrade it to 2-0-2, providing support and discount synergy.
- Around the Village and Skeletor, place six Druids, ensuring they benefit from the Village buffs.
- Upgrade the Village along Path 3 to 2-0-4 for even more income.
- Add two additional Banana Farms, also upgraded to 2-0-3.
- Upgrade all your Druids to 0-2-4, turning them into powerful support attackers.
- When the Round 35 DDT appears, use Obyn/Skeletor’s Wall of Trees ability to instantly stop it.
- Your defense will dominate every wave — at this point, place as many 2-0-3 Banana Farms as your map allows to push your economy even further.
- Upgrade your Mermonkey to 5-0-2 (Lord of Abyss) for maximum power.
- Upgrade your Wizard Monkey to 0-2-5 (Prince of Darkness) for tremendous damage and cleanup.
You’re now ready for the final step.
Final Step: Achieve 333,333 Cash
Before Round 60 begins, sell all your Banana Farms. This will push your total cash extremely close to (or above) the required 333,333 Cash.
Sell a few extra towers if needed — and the mission is instantly completed.
Skeletor Gathers Power is a farming-focused mission that looks intimidating but is actually very straightforward once you follow the proper sequence. With efficient Banana Farm scaling, a reliable Mermonkey path, and strong late-game magic support, you’ll reach the required cash well before Round 60. This completes the Skeletor tale and wraps up the entire Oh No! Skeletor! questline. Enjoy your victory and the rewards that follow!
