Talents

Talents are upgrades that are unlocked alongside the Skeleton Champion. There are 4 talent mastery lists available: Golem, Skeleton, Spell, and Zombie.

To obtain talent points you must use Prestige points to purchase them, with the cost going up with every purchase. You can reset you talents to reassign them, though you can only do this once every prestige.

Talent Points Cost
The cost of the first talent point starts at 100 prestige points and the increases by 20% for each talent point acquired. The total cost to unlock all talent points can be given by 10*12 points = 120 points to unlock, then $$\sum_{n=1}^{120} 100 * 1.2^n = 1.9E+12$$ or 1,900,000,000,000 or 1.9 trillion prestige points.
