Ten rebirths, and no printed price
The description caps rebirths at 10 and the tutorial reading says each match gives skill-tree XP, without printing rebirth prices.
The description lists skill trees, upgrades, and 10 rebirths in one line. It does not say what a rebirth spends, what it keeps, or what the skill nodes are called. Munyecoh's tutorial reading says every match turns XP for the skill tree and that the balance buys gadgets, energy drinks, and cases in the shop. Those shop categories are not the same rows as the Robux cash packs. The Robux packs add in-game dollars. The tutorial's gadgets and energy drinks were not given prices in that page text.
Samwel's page text says "Now we can faster stamina recovery again" after an upgrade click the player calls a steal tree. That is one spoken effect, stamina recovery, from one video. It is not the whole tree. This page will not turn that sentence into a node chart.
A calculator for rebirth number 4 or for a skill point would have to invent the cost. That form is not on this site. When a source prints the table, the gap can close. Until then the usable facts are the cap of 10, the XP line, and the separate Robux shop.
