What sources say — and where they disagree

Name and 129 R$ tier confirmed independently (rbxdata, bloxron). ×70,000 and the 22.5M Water price appear only in the guide lineage; bloxron's in-game table instead puts 22.5M on Demon and calls everything above it Robux-only. Values shown with that caveat.

We record conflicts instead of quietly picking one value. See methodology.
