A set of saves that go along with the splits for my true end any% run, which put each boss in a different split. The saves are titled based on the boss at the END of the split, for example aquaserpent.dts starts immediately after thunderbird. There are a few saves which don't align directly with bosses but it should be pretty clear what part of the game they're for by the title.

If you want to reroute upgrades/equipment, that might throw off these slightly for practice use but they're probably still helpful.
