Mod Reviews
Improved Stronghold

The true adventure update!
With the only change to the overworld, the Stronghold now is much more bigger and has several redone rooms. Along with some custom mob spawners bringing forth a bit more challenge to your adventures such as invisible cave spiders! The new stronghold has two levels too it, with the second level including the portal room and the library.
Changes to the Base End Biome

(Upper Left) The Avalon, a mysterious trader that can rarely be found offering enchantments and upgraded weapons for a price. You can also find the Avalon's Coin for a unique challenge.
(Upper Right) Turium, a new plant found rarely in the biome or at any of the structures found in the base end biome. When eaten, it gives Regeneration 2 for a short period of time.
(Lower Left) Compulsors, machines that suck up any entities or items. Great for farm utility or making traps at your base.
(Lower Right) Ancient Guilder, a new denizen in the end that doesn't really like anything Ash Wasteland's related and can be given items that'll display in it's head. If you place the requested block near it, It will convert that block into a different one.

The End Vaults
This structure is where you can find the end's new resource, Pure Crystals. They are heavily locked away and these vaults can be found by looking for a well like structure on the surface or poking throughout the side of the islands. They are known for being heaily guarded and the chance for a mini-boss to be at one of these is by chance.

The Lamented Islands
This behemoth of a floating city is where the first major boss is found, it is reccomended to defeat the Lamentor to get an idea if you're ready to head to the Ash Wastelands. You can also find a small amount of Pure Crystals here as well.
The Ash Wastelands

The Ash Wastelands
This biome is filled with hostility and a dark shroud of fog lies in it when entering. However it holds the key to some of the most powerful equipment in the mod and bringing forth more utility machines.
(Upper Left) The Dark shroud within the Wastelands and some peery eyes, best to light up the area.
(Upper Right) One of the new resources found in the biome, rarely on the surface but more common in the underground. These crystals are to be combined with Pure Crystals to be the base material for the best armor set in the mod.
(Lower Left) With the Wastelands, it holds it's secrets in the underground as well with the Ashed Mines you'll be able to explore large cave systems and encounter new life. As well this is where the second resource is found, Cordium.
(Lower Right) We can see one of the denizens of the underground, it likes to latch onto your head if you wake it up.

End Game Structures
(Left) We have the Ashed Towers, looming over the biome and holding puzzles, traps, and the best chance to find an Avalon's Coin atop of the tower. As well where the Fell Knights guard there treasures, and another chance for a mini-boss to spawn atop of the tower.
(Right) The Ashed Kings Fortress, this massive behemoth of a floating fortress is the final stop in the mod. Where you'll encounter several variants of the Fell Knights, and at the top of the main building is where the 2nd and last major boss is. Make sure you have the best equipment you can take as enchanted diamond armor doesn't cut it.

FAQ:
Will you port this to a newer version?
A: As of now it is a no, it all depends on how smooth the porting for another smaller mod goes and if I wanna take that risk with this mod. But if it does port forward, it will be when the Barrend Bogs update is complete.
Will there be any more updates/additions?
A: Good news! this project will be slated to get another content update, it may not be as massive as the Wake by Ash Update, but it is at minimum to include some new creatures and a new biome!
Will you be making parts of this separate mods or changing the Ender Dragon?
A: Yes, I do plan on making the Better Stronghold it's own mod in the future and that second part is classified. :)
