To round off the end game, I need the following things:

• A way to spawn the 3 legendary spirits
• Compelling ways for the players to get the 3 orbs to summon Palkia, Dialga, and Giratina, that are appropriately gated.

After that, there's still a lot to put in the modpack. For instance, Thermal Foundation is in the pack, but the other Thermal mods are not in the pack because they violate the modpack's aversion to single-block machines. But I think it's reasonable to add in Thermal content that's gated until very late in the game, and maybe even Big Reactors to help power it. Access to additional spawning eggs, like Basalz/Blitz/etc spawn eggs, should round out access to materials.

Thermal, once combined with the ores made available from Botania and Astral Sorcery, will be able to rapidly increase player resources and let them transition into a builder-focused phase of the game where they're just making their void palace as cool as possible, and possibly trying to complete their Pokedex.

I'd also like to put in ways to summon and fight more boss Pokemon, and I'd like a more satisfying end to the Extradimensional invasions questline, where you've been getting harassed by mobs and decide to take the fight to the mobs. There really should be some kind of capstone boss to fight, or a dimension to visit. Alternatively, this can be the start of the 'biomes in jars' availability.

End game has been added. The three legendary spirits spawn in the three dimensions the player has access to, and also created quests that can spawn 1 guaranteed encounter.

The player has the option of looking for the Lustrous orb the old fashioned way (End Cities), finding and fighting an ultimate boss, or they can do the Evil Forces questline and guarantee a fight with a boss 20 levels lower than ultimate level that's sure to drop the orb. Similar quests exist for the Adamant and Griseous Orbs as well.

Additionally, chest loot has been added to defeating the gateways, and this means one can defeat the shulker gateway to have a chance at getting the Lustrous Orb.

Pathway untested.
