After testing the Jungle item for a long time, I came to the conclusion that the red one is the best. The reason for this is that you then have a slow on Teemo’s “Q”. The range of the “Q” is higher than the autoattack range of Teemo. The slow on the Q makes it easier to get into range so that you can deal damage with your normal attacks.

As mentioned at the beginning, Nashor’s Tooth is the most important item for Teemo in the Jungle. In combination with the on-hit damage of the “E” and PTA as a keystone, you deal a lot of damage. Then go for the Spell Shoes to get the necessary penetration on board and buy the second most important item; Liandry’s Torment. This synergizes incredibly well with Teemo’s mushrooms. The third essential item is Malignance. Even if you don’t necessarily need the mana values, they are still nice to have. In addition, the effect is brilliant for Teemo’s mushrooms because it is activated twice by the mushrooms’ Dot (Damage over time). This creates additional AoE fields, all of which also reduce the opponents’ magic resistance. This not only helps Teemo, but also every other champion in the team who deals magic damage.

After these 3 core items, you have various options. I recommend items such as Shadowflame, Crypbloom or Zhonyas. These items are particularly good because their effects are extremely helpful for Teemo. Due to the fact that the AP scaling is not particularly high, I explicitly do not recommend Rabadons (unless you are full item build and have enough gold). Lower AP scalings ensure that the high magic values of Rabadons are not utilized efficiently.
