Teemo gains invisibility if he stands still for 1.5 seconds without acting or being acted upon. He will remain stealthed so long as he doesn't move, doesn't act, or is displaced. If within a brush, Teemo gains stealth after 0.75 seconds even while moving and may move freely within its boundaries without breaking stealth.
When Teemo breaks stealth, he gains the Element of Surprise for 3 seconds, granting him 20 / 40 / 60 / 80% bonus attack speed.
Passive:Teemo stores a Noxious Trap charge periodically, up to a maximum of 3 at once.
Active:Teemo tosses a mushroom trap on the ground, which stealths and arms after 1 second, lasting up to 5 minutes. While armed, mushrooms grant sight around them.
Mushrooms thrown on top of each other bounce on the previous one a short distance before planting.
If an enemy steps on a mushroom, it detonates, poisoning all nearby enemies, slowing them, granting sight of them, and dealing them magic damage over 4 seconds.
