YUNG's Better Strongholds (Forge)

 A complete redesign of Minecraft strongholds like never before, making them much more complex and exciting while still staying true to vanilla themes. There are over 15 different rooms, various types of tunnels and hallways, staircases, traps, and even hidden areas!

YUNG's Better Strongholds is intended to be fully compatible with every worldgen mod.

• Better End - Fully compatible. No action necessary.
• Endergetic Expansion - Fully compatible. No action necessary.
• Repurposed Structures - Fully compatible. No action necessary. Use the latest version of Repurposed Structures!!
• Save My Stronghold! - You no longer need SMS! Better Strongholds includes all the functionality of Save My Stronghold built-in.
• End Remastered - The ER team is working on it. There will soon be a setting in the ER config for allowing ER eyes to be used in vanilla portals. Better Strongholds will generate in addition to ER's End Gate and End Castle. In the meantime, you can still use the mods together, but you need to enable vanilla eyes in the ER config, and you won't be able to use the portal in the Better Strongholds to get to the End.
• Other - Certain specific mods that add custom dimensions, like Lost Cities and Gobber will need their overworld-like dimensions whitelisted in order for Better Strongholds to spawn in the overworld. This is because these custom dimensions use the same internal settings as the overworld. Note that this doesn't apply to most dimension mods, since most modded dimensions have entirely custom settings.
