Of course, I do know about Nether Void, but to do so you have to farm there until you get keys, then you have to go kill the otherworldy serious bosses, and wait for them to give us the 150 mystic gem (as the drop is random), The idea of this video is just to go kill, since it doesn't take more than 10 minutes, it's a good idea, of course your suggestion is also good, but there it requires more time, it would be a matter for each player. Either way, I appreciate one more alternative.
