Zagreus Shares & loop

The Zagreus project constants.

Shares required	100
1st Share cost	10²⁸⁰
Cost exponent	×10
Loop gauge (base)	10¹⁰
Growth per cycle	×10¹⁰
Bonus exponents (1–6)	1.02 · 1.03 · 1.04 · 1.05 · 1.06 · 1.07

Example

The Zagreus project requires 100 Shares; the first costs 10²⁸⁰ (×10 exponent). The loop gauge starts at 10¹⁰ and grows by a 10¹⁰ factor.

Cost currencies (OG Tech, Shares, non-milestone ZAT advancements) are not serialized — in-game validation pending. The game's narrative logs are not republished.
