MvP Tombs are already available for the new revisions?

[Zephyr]

I downloaded the rAthena now from the Git Hub and I started to search about the MvP Tomb diff, and when I went to apply it, I discovered this line on battle.h:

int mvp_tomb_enabled;

Is it MvP Tomb already available and functional? How can I edit this, for example, make a custom boss to spawn the tomb, and how to disable the time.

 

If not, someone can give me the updated diff to add it?

just like how any other normal mvp did.

 

spawn using the "boss" flag.
