Whenever Poindexter has to generate a new Bogey, they should secretly randomly determine its Energy, Attack and Defence based on the published ranges, and secretly randomly determine whether it has any of the native special features for its sub-species.  While a Bogey’s numerical statistics can never exceed the maximum of the respective ranges for its subspecies, once it has emerged, it is legal for those statistics to be reduced below the minimums of their respective ranges by various means.

In the rule “DEVA Sub-species”, change

a list of possible special features

to

a list of native special features with the probability a new individual of that sub-species has each of those features

Add a new sub-rule to the rule DEVA Actions. Call it “Hibernate” and give it the following text:

A Bogey can only schedule the Hibernate action when its Energy is below the starting minimum for its sub-species. If a surviving Bogey has 1 or less ENERGY, its next scheduled DEVA action is replaced by a Hibernate action.

A Hibernate action is a staged Timed action with the following stages:
* 8 Hours - Torpor
* X to Y Hours - Dormancy
* 8 Hours - Stirring
where X is half the difference between the Bogey’s current energy and the starting minimum for its subspecies, and Y is half the difference between the Bogey’s current energy and the starting maximum for its subspecies.

When the DEVA starts Stirring, it gains 2 Energy for each hour it spent in Dormancy, rounded to the nearest whole Energy.
