Great for Exploring, Worse for Performance

IDAS is a great structures mod with impeccable design, numerous secrets and an overall fantastic generation that is only held back by the fact that like most structure mods, it adds noticable strain on the server.

Many of the structures are full of minor lore, easter eggs and secrets that reward you for interacting with Create, Supplementaries and the other many mods that have integration with this mod. It resembles Dungeons Arise but with more reasonably sized structures and a better application of mob spawners.

I recommend combining this with a mod for managing structures in order to control their frequency, spacing and to disable unneeded structures (e.g. if you don't have fire and ice installed, you can disable the related structure and keep the error logs down a bit).

All-in-all a lovely mod that I can rare do without these days.
