The Wyden grants a massive +5 HP at level 1. Then another +1 HP per level as you power up your Wyden. Wydens can only level by defeating other Wydens in a future 1v1 tournament.
Multiverse Mikes Hero HP buff is dynamic and increases as the Kingdom Karnage player base increases in relation to the circulating supply of Multiverse Mike NFTs.
The Wyden is the most powerful Hero. He is sold out and only available on the in-game marketplace or JumpNet Marketplace from other players.
