Heart of the Mountain

The Heart of the Mountain, commonly abbreviated as HotM, is a skill tree related to.

As players level up their Heart of the Mountain, they will gain Tokens of the Mountain, which can be used to unlock various perks. Some of these perks will take effect only on public islands with new mining mechanism (alongside with infinite Mining Fatigue).

Mechanics
A Heart of the Mountain Menu showing all perks up to Level 7 at max level.

The menu can be accessed via the, while inside the and , via the  menu, or anywhere via the   command.

Players can level up their Heart of the Mountain tiers by gaining HotM experience, which can be accumulated by completing Commissions and participating in various active mining events. Note that unlocking the whole tree at the same time is not possible, due to the insufficient amount of available Tokens of the Mountain.

Each Commission completed in grants  experience, and each one completed in  gives  experience. Players receive additional experience from completion of the first four Commissions, if the Heart of the Mountain tier is below 7. Otherwise players earn additional 1,600 or  instead, depending on the area.

The Heart of the Mountain can be reset. This wipes all of the Heart of the Mountain upgrades and returns all spent, and Token of the Mountain. However HotM tier and Peak of the Mountain levels are kept; thus powder spent on upgrading Peak of the Mountain is not reimbursed. The first reset is free, but each subsequent reset costs. Resetting the Heart of the Mountain has a cooldown of hours.
