Heart of the Mountain

The Heart of the Mountain (HotM) is a skill tree from the Dwarven Mines update.

As players level up their Heart of the Mountain, they will gain more Heart of the Mountain tokens, which can be used to unlock various perks. These perks will only take effect on public islands.

Heart of the Mountain Menu
A Heart of the Mountain Menu showing all perks at max level. Note that unlocking the whole tree isn't possible at the same time, due to insufficient Heart of the Mountain Tokens available. The menu can be accessed via the SkyBlock menu (only while inside the Dwarven Mines), via the Mining skill menu or via.

Gaining Heart of the Mountain Experience
Players can level up their Heart of the Mountain by gaining Heart of the Mountain Experience, which can be obtained from Commissions and from events such as Raffle and Goblin Raid.

The first four Commissions players complete every day will give an additional 900 HotM experience for a total of 3,600 extra experience. Note that once the player reaches Heart of the Mountain 5, they will gain extra Mithril Powder instead of HotM experience.

Tips

 * At Heart of the Mountain 2, it is recommended to unlock Titanium Insanium.
 * At Heart of the Mountain 3, it is recommended to get the Mining Speed Boost ability and to spend the last token on either Daily Powder or Luck of the Cave.
 * At Heart of the Mountain 4, it is recommended to get Efficient Miner and to spend the last token on either Luck of the Cave or Seasoned Mineman.
 * At Heart of the Mountain 5, it is recommended to get Peak of the Mountain and to max it to obtain 2 more Tokens of the Mountain. Then, players can go through the Mining Speed Boost to get Sky Mall and Goblin Killer. The final token should be spent on either Quick Forge or Seasoned Mineman.

Trivia

 * While it is possible to have both abilities unlocked, it is slightly convoluted to use both. Players must use one ability then select the other in the Heart of the Mountain Menu in order to use it.
 * The Mithril Powder from the Daily Powder perk resets once every real life day, not every Skyblock day.
 * Despite being impossible to get every single perk in Heart of the Mountain if you were to get all of them and max each one out it would cost 16,223,038 Mithril Powder.
 * At 1 powder per second (86400 per day) this would take about 187 days to get this amount of powder.
 * It's possible to completely reset your HotM skill tree, refunding your tokens and all mithril powder. It's free for your first reset and 100,000 coins for subsequent resets. Resetting the tree has a cooldown of 24 hours or 1 real life day.
