Better Ultra Secret Rooms
This pack adds 125 diverse ultra secret rooms to spice up your Red Key shenanigans.
* 78 layouts have a random item from the Ultra Secret pool, 77 of which also come with a free Soul of Eden, allowing to reroll the said item into a different one from a random pool;
* 46 layouts have a non-ultra secret item which they are designed around, but these rooms always come with a free Dice Shard or Soul of Isaac, so you can reroll it into something from the Ultra Secret pool;
* 1 layout (the one from the thumbnail) has Chaos, because why not.
Some rooms may have a couple of enemies in them, so be careful.
