# Fusion Regeneration

Combine either a Genesis Hash or a General Hash to regenerate a monster through fusion. Typically, a genuine seed with matching main and sub seed is produced; however, a derivative seed may be generated through this process.

Rather than consuming both regeneration times, the ability of the resulting monster tends to surpass that of monsters created through normal regeneration. Moreover, unlike the regular fusion, this method does not lead to a decrease in the monster's lifespan.

The cost will be the average of the normal regeneration of the two Hashes.
