Gaslight Joker is a very unique champ which relies only on his health not on will or rage or anything like that, thats why all the items that are build on him should have health scaling. Since he is an enforcer his main purpose is to soak up damage and to slow or stun or in this case fear the enemy and disrupting the enemy team. The core items are more or less a must on him but depending on the enemy team you can chose the last item from the defensive items. For offensive build the only item I would reccomend is Cosmic Belt because he is a tank and is not supposed to do damage. Hope you guys like the guide and have fun carrying with the fatty XD
Item Explanation :
Nil Cloak and 3 health vials should be the the opening items for every enforcer and Gaslight Joker doesnt make an exception, thats because of the early and very good stats that Nil Cloak gives.
I like to go for Ruby of Life because it gives a lot of health, health regen and also it has stacks, so the earlier you get it the earlier you can collect the stacks.I would reccomend to get Ruby of Life to Tier 3 and then continue to Diana's Bracers. Diana's Bracers is a very good item on Gaslight Joker because it gives you attack armor and a lot of health regen especially with the health balance keyword where you get extra health regen for mising health. After that you can decide to go for Suit of Sorrows or Mirror Master's Prism depending on the enemy team but I would still get the one that remains afterwards because the reflect is too good.The other items you can build depending on the other team.
