The Perk Tree features unlocks and upgrades for many of the features of Idle Skilling. Players gain perk points by leveling up their skills in the game. Once earned, these perk points may be spent in any of the first three branches and later on in the last four branches once they're unlocked permanently after clearing Grasslands, Desert, Mountains, and Purgatory. There are no restrictions to which branch perk points may be allocated to, therefore it's possible to fill up all six trees simultaneously, although it requires 2601 points to do so.
Initially, each individual perk can be upgraded up to 5 times. However, once the Skilltree Overcharge Ascension Perk (+5 max), All Star Rebirth Perk (+5 max), and Tressii Brew Bobby Potion (+35 max, excluding 3 perks) are unlocked, perks may be upgraded up to 50 times (only 15 times for Smithing Multi-Craft, Poison Attack, and Botany Overgrowth Time Redux).
Perks in the Infinity Tree have no cap, and can be upgraded forever, with the perk point cost increasing by 1 each upgrade. You start with 2 perks in the Infinity Tree, and unlock more as you bring Ice Creams to Dairy Aisle.
