Well WoTC had made another crossover with an established IP again. This time with League of Legends. The thing is though, It's free and digital only on DND Beyond. Some interesting notes about it.
They pretty much made their own "version" of the Mercer Gunslinger Fighter Archetype called Renegade. It's interesting because it has a feature where you can upgrade your gun and add stuff to it. They legit made a Gunblade option for the Pistol. It is also a CHA fighter since the Fire Arms Upgrade DC fuels off of CHA.
The Rogue is pretty interesting. You can subtract dice froma special "Loaded Dice" pool ,that equals your Sneak Attack Dice Pool, to decrease damage against ya and you get special abilities that change effects and also can use your Sneak Attack Dice Pool as well. It's a CHA Rogue as it's Save DCs are CHA as well. Also it's capstone "Super Mode" that a number of classes get seems really legit.
The Barbarian can breath underwater, has a Force Damaging Teleport, and the ability to multi grapple s number of things via Appendages. It's interesting.
Even if you don't like or play League of Legends, those are some pretty cool Subclasses. And I make the Argument that if you play the Mercer Gunslinger, you can jack the Renegade Firearm Upgrades to use on your guns. Whether you use CHA still or fuel em off of WIS, or even just treat them as basic upgrades. My personal opinion is choose whichever you want it to be.
