The upgrade system in EtherForge allows players to enhance the power of their Heroes and Monsters by consuming in-game resources and $ETHER energy.
Each Hero or Monster has a unique stat that can be upgraded from Lv 1 → Lv 10, representing long-term progression and evolution over time.
Level Progression by Rarity Tier
Each rarity tier determines the growth rate and the $ETHER upgrade cost, helping maintain economic balance between new players and high-investment players.
This upgrade progression encourages strategic investment, allowing players to optimize their lineup for both PvE efficiency and PvP dominance.

2/ Token Deflation Mechanism
The upgrade system serves as a core $GENESIS token sink, helping control supply and increase scarcity. Specifically, 100% of the $ETHER spent by players on upgrades is converted into $GENESIS and permanently burned, forming an effective deflationary loop that:
Maintains long-term token value stability
Drives continuous and sustainable on-chain activity
Aligns player progression with the increasing scarcity of resources
This mechanism ensures the EtherForge economy remains self-sustaining, value-balanced, and durable over the long run.
