Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Ive tryed a few of the tank trundle builds but in the end this build helps me to survive and do alot of damage as trundle at the same time. It starts off by giving trundle good speed to run away in certain situations while giving him enough attack speed at the same time to be able to down other champions quickly. The first five iteam you get are always going to be the same then the last iteam slot usually veries dependant on how late the game has gone and if u need more survivability versus damage. If you just need to kill i normally go with the phantom dancer for the last iteam if u need a better chance at surviving i go for a thornmail against melee heavy teams and guardian angel for a caster heavy team. This probably isnt the best build in the world but i noramlly average about 10-4-20 against melee heavy teams in ranked and get anywhere upwards of 20 plus kills against caster heavy teams.
