[Patched] Tombstone Bug Abuse Solo Boss - Undying - Aghanim's Labyrinth 2 (2021)

The new way to Tombstone abuse:    • Wooden Crate Tombstone Solo Boss Abus...  

Patched on 19 January 2022.

Sorry about the sound, it's a party game and my friends keep spamming weird annoying words so I delete the audio and slap some NCS instrumental.

All you need to solo the bosses is stand where I stand in the video, you need to do this so you will not aggro the bosses (except the final boss). Next, you want to put the Tombstone at your max range. That's it, I can't explain more than this because this is all that I and people do and I did not want to waste your time by extending the video by 5 or 10 more minutes.

You can solo most bosses except the Wriggling Wreef (the boss blob that split) because you're forced to stay inside the room when the boss scene started and because of the split, probably you can abuse the big one (I'm not sure) but after the split, you can't abuse it anymore.
I haven't tried Eldwurm Aerie (Winter Wyvern). I have tried Rizzrick the Razorsaw's Deep Cuts (Timbersaw) but failed, but I'm pretty sure you can abuse him but I don't know the spot yet. All you need is patience and time, also Tombstone cooldown reduction and duration for the final boss.

Edit: You CAN NOT abuse the amoeba split, timbersaw, and tiny with Undying. The rest of the bosses are abusable.
