Before we start, i need to introduce who is Batman aka The Dark Knight. Batman is actually a superhero without any super power but rich. Yes, he is rich and he scare bats when he was young, then he just become Batman when he is grown.

The first and the most important armor to become the Batman is the Black Knight Helm.
The Black Knight Helm can be dropped by the Black Knights. One of the first Black Knight is near the Farron Keep Perimeter bonfire. You can found a lot more BK after you defeated Champion Gundyr, there is about 5 to 6 Black Knight near the Firelink Shrine in the Untended Grave.

The second armor is the Drang Armor. Of course you can change to other similar armor in order to look like Batman.
Drang Armor can be found in Cathedral of the Deep, it scattered around a giant near the stair. There is lot of something like muck monster under the giant, in case you not sure which giant it is.

The third part of the Batman set is the Ringed Knight Gauntlets. This gauntlet is quite important in order to look like batman because of the horn thing.
The Ringed Knight Gauntlets can only be drop by the Ringed Knight in the Ringed City DLC. Good luck !

The last part of the batman set is the Dark Leggings. But you can choose whatever leggings you want, i'll chose this one because it look like armored leggings.
This legging can be drop by the Darkwraiths in Farron Keep or High Wall of Lothric. I recommend farming the Darkwraiths in the High Wall of Lothric its a lot more faster than the other for me.

This is how the whole set look like.


This is the third person view of the set.

Ceastus will be great weapon choice for Batman, because Batman mostly fight with fist in the movie.
And buffing with Human Pine Resin ( Dark Magic ) , darkness is the ally of Batman.






Having some projectile item will be perfect for Batman, it may not deal much damage on enemy but it can stop enemy from drinking estus. Three item below is good to use but the Church Guardian Shiv is more recommended because its unlimited and its blue color.

At first i thought it won't actually seem like batman, but when i try about the final result kinda surprise me, you too gotta try it. Special thanks to @Gentleman Dog for suggesting weapon idea for this guide ! Thank you for viewing this guide by the way, hope you like this guide and the batman cosplay. Long may the sunshine ! \ ( ---- ) /
