at 100 stacks, you get a 10% buff of the stat you chose. the buff is a persistent effect and remains after item is sold. can buy multiple upgrades, but only stack one at a time. the movement speed buff and mana(also energy) would not be affected until the stacks are completed. the stacks mean nothing unless you finish the full set of 100. large minions/monsters, kills and assists count for 3 stacks.
