Your Worshippers start with Energy equal to the total Power Strength of all your other Mutations, multiplied by two.
The US Military have 100 Energy. At the start of each round, they will decide to Attack the Monster with the most Energy for 20 damage (or as much of 20 as possible), and to spend the rest on Defence.
Reverting to Human Form
The Monster(s) who bid the least on this Mutation will revert to human form at the end of Round 5; they will lose all Mutations and have their Energy set to 1.
Everything Is a Projectile
Your creative use of the city as a weapon adds this Mutation's Mutation Strength to your Attacks but also earns you the wrath of a 20 Energy Militia which Attacks you for 5 each round until slaughtered.
