New Monster: Adult Alatreon, my first mythic monster

Hi All,

I am finally satisfied with the Alatreon and its loot table. The play tests we did in the prior month were quiet successful in my opinion, but it did require some minor tweaks to the stat block, mostly making it so its attacks count as magical and settings some DCs and ranges for skills I initially missed. 

The first group that attempted the fight went in blind and did well until the first judgement hit. None of them died to it, but it weakened them so much that the alatreon wiped them out in the new few turns.

The second group, were some of my hr5+ patreon players and went it with some insane builds along with adjusting their materials to combat the alatreon. By the time the first round occurred the alatreon was able to use its judgement and the party found a way to avoid it, basically saving themselves from a tpk. I still killed one PC by the end, but with min/max brute builds they did end up killing the alatreon in the end.

The final group, were more common classes and builds you might see in a standard 5e game, though most of them were ranged characters.  The fight lasted 4 hours and during that time they avoided the first judgement taking a note from the second group and ended up healing themselves to full twice during the fight. It was intense but well played.

The Alatreon is a CR 30 monster that's power rivals the Tarrasque with more ranged attack options. It will not be an easy fight and PCs who go in without the proper gear/materials will find this fight to be almost impossible, or require an insane amount of luck and skill. 

Normally I would have added this to the MHMM, but due to issues with the clickable table of contents right now on GMbinder, I have decided to to wait until that issue is fixed to add it to the manual. 

Please let me know what you think and I hope you enjoy sending this beast up against your players.
