Hello everyone, I hope you are doing ok

I'm doing some ILs in the DLC category (which must include builds from the DLC, i.e. Chalice, weapons or charms from the DLC). However, I've seen a lot of WR of these categories with no builds from the DLC, for example, runs with just mugman, charge-shot and wetstone. This is seen more cleary in plane levels, uploaded in the DLC category, but the build is Cuphead and Wetstone. Am I missing something?

No,some people just prefer playing as mugman.

I don't know if you understood my question

I have seen runs in DLC content ranking that did not use any DLC weapons, charms or chalice.

for example

https://www.speedrun.com/cuphead/run/mr7gdq7z

Of course you can use cuphead/mugman, but you need to use at least one DLC weapon or charm

I'm not complaining or anything, I just want to know what am I missing and why these runs are in DLC category despite not having any DLC items

Both of the runs you linked are using the Divine Relic charm, some people also use Heart Ring for plane levels or Twist-up as secondary weapons in ground levels

Ohh, I get it now, Divine Relic max charge was the thing missing there, thank you a lot for your answer!
