The beta boss randomization is a rework of the previous boss randomization feature. Where the legacy boss randomization only swapped single-target bosses with other single-target bosses and did the same for double-target bosses (leaving bosses with 3 or more targets as they were), the newer version does a much better job of mixing them up. Single- and double-target bosses can not only mingle with each other, but with few exceptions, bosses with 3 or more targets are now part of the shuffled pool as well.

While this version of boss randomization is much more popular with the player base, it is still being tested, and the information on this page is subject to change.

The following bosses will never be shuffled from their space, even with Boss Randomization enabled:

• Dragon Tank
• Masa/Mune (twins form)
• R-Series
• Magus
• Azala & Rust Tyrano
• Final Bosses (Lavos, Queen Zeal, Mammon Machine; all forms)

The following bosses are eligible to be shuffled when Boss Randomization is turned on (bosses that do not appear in standard mode are marked with an asterisk):

• Yakra
• Guardian & Bits
• Heckran
• Zombor
• Masa & Mune (combined form)
• Nizbel
• Slash
• Flea
• Nizbel II
• Retinite
• Golem
• Giga Gaia
• GolemBoss*
• Dalton Plus*
• Yakra XIII
• Flea Plus*
• Super Slash*
• Son of Sun
• Atropos XR*
• Mother Brain
• Lavos Spawn (one only)
• Mega Mutant*
• Giga Mutant
• Terra Mutant
• Elder Lavos Spawn

In 3.2 Boss Randomization, the twin boss is not treated as a separate “single” slot with two targets as it was before - it can now be a repeated “twin” of a boss that players have already seen in the seed. The major things to note are that having already seen a boss does not exclude it from appearing in the Ocean Palace and Dalton Plus is now eligible for the Twin Boss slot (previously he was banned from it for being too difficult - balance changes have also been made to accommodate this).

Currently, the beta boss randomization uses a formula to scale boss HP depending on the location where it's slotted. There is a spreadsheet of this info from the guides page.

We are looking into using spot-based HP like the legacy boss randomization had, but it needs to be tested further and for the time being the above will remain in place.
