If you fall you will be teleported back to the nearest land mass. Just FYI. Used mek and kod 3 each with 1 shot to the head. Highest level 100 lowest level 25. Use hazmat suit to be able to move around in radiation and not burn to death. Bring med brews and stew to counter freezing.
Singleplayer taming is so hard. I had nobody to aim the cannon, and I'm currently waiting for the astercetus to wake up. I struggled so hard. He's a blue level 8. LEVEL 8. Dododex says there's a 93% chance of death for the cannon for a level 8.. Pretty lucky, eh? Singleplayer taming is.. Hard. Not impossible, though. I managed!
