Well tbh trinity is really expensive to buy at early phase if the game is going pretty normal. but if u dominate the early game with good ganks and have plenty of kills and assists to efford the trinity force in early - mid game it gives really good damage.

and we take enemies down really quick. becuz of kill and level advantage they can not kite us really hard. so we can take someone down in a second or two with a simple Q+Q+Basic attack +Ulti then a safeguard to an allied minion or hero combo

But if things just normal and we rush to trinity we will become a glass cannon which doesnt fit Lee Sin's gameplay in my opinion.

we go down really fast just with a simple focus in a teamfight if we rush to trinity.

Also you can decide to complete trinity before banshee in the game if there is not a big caster treat at the enemy team. but i never recommend to complete trinity before atma if the game is going tough

Good build, just one q why trinity force so late?

Ty for the info bro. it is my first guide and i will try to upgrade it with more info in the following days

Oh, and remember to turn on "comment to vote", or else you will get troll downvotes from people that don't even explain why

Not a bad build, although I do go a different route. Items make lots of sense to me, and the runes are good as well. Overall, this is a nice build. Great job
