Mountain Leveling

Mountain level is the main progression clock. It raises health, changes rewards, opens artifact choices, adds den opportunities, and eventually points you toward special mountains.

Health	Mountain max HP uses a level-based base value, multiplies it by 1.115 per mountain level, rounds it, and never lets it fall below 1 HP.
PP Reward	Awards +1 PP at the next prestige reward level, then moves the next PP reward ahead by 1-3 mountain levels.
Soul Reward	Every fourth level after level 1 can spawn a Soul and lowers base gold per damage by 0.01, down to a 0.3 floor.
Artifact Choice	Offers 3 artifact choices at level 2 and then every third level after level 1; level 49 banks three choices before the level 50 Triple Seal Gate.
Den Count	Every mountain starts from one den roll, then makes up to three extra den rolls with chances that rise by level. Spelunker multi-den bonuses multiply those extra-roll chances, with a minimum multiplier of 1.

Leveling Priorities

Progress Point	What To Do
Levels 1-2	Build damage and hauling first. Artifact choices start early, but weak economy makes every bad buy more painful.
Dens appear	Treat den clears as part of progression, not a distraction. Dens feed artifacts and mithril.
Every fourth level after 1	Watch for soul rewards and the gold-per-damage reduction. Soul matters more once rituals and late upgrades are available.
Special gate level	Before the Level 50 gate, keep Ruby Key, Sapphire Key, and Emerald Key. Before the Level 100 spire, compare against the Great World Spire checklist.
World Spire path	Shift from normal economy into required artifacts, PP, mithril, and permanent scaling.
