Koroblins enter a second form when they are about to die from blood lost. When a Koroblin is reduced below 0 hit points, they do not fall unconscious. They instead enter a second form that is unique to themselves, changing in appearance and gaining some new abilities. A Koroblin can be in their second form for a number of rounds equal to 3 + Constitution modifier. Once entering their second form, a Koroblin gains a number of temporary hit points equal to half their maximum hit points. Being reduced below 0 hit points second form causes a Koroblin to actually fall unconscious, or die if dealt enough damage.
A 2nd form can not use any wepons they normally can unless they can a ability that allows them too
There are 3 basic types of second forms, But some classes have there own architypes of second forms. When creating second form you choose a Basic form, you can stay with just the basic progression of a second form or use a class specific progression. (I'm going to have people help me with this later this is a WIP)
Some of these 2nd form progressions are locked only to Half Koroblins.
