About this Mod

About:
Luki's Strongholds is a structure overhaul mod for 1.20-1.21 focused on transforming the titular structure by introducing new mechanics and a fresh new look. Vanilla Strongholds don't offer very much in terms of gameplay. Sure, they house the end portal, but not much besides that. Luki's Strongholds aims to mend that.
The structure now features Trial Spawners and Vaults, creating a more engaging gameplay experience before entering the End. In these vaults, you can find end-related items like Phantom Membranes and Dragon's Breath, as well as equipment to finish rounding out your gear before the End fight. You can unlock these vaults by utilizing the two brand new types: the Stronghold and Dragon Key.
Attention:
While this pack has a version for 1.20, this structure was created using 1.21 mechanics. The backported version excludes these mechanics. If you want to experience the Strongholds at their best, please use on more recent versions. (If you're a content creator showcasing this mod, please use the 1.21 version!)
There may be complications with mods also featuring custom keys, like Dungeons & Taverns. This will only affect the texture, however.
