Making a 2nd form

Second Form:

Koroblins enter a second form when they are about to die from violence. 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. No two second forms are the same, however they do tend to share some similar traits. Choose one of the following compositions to determine what physical form your koroblin takes upon transforming.
Ooze: Your form becomes melted and indistinct. Some koroblins in this form retain a humanoid shape, however this is not always the case. You take a -4 to Dexterity, however you gain DR 5/Slashing. Whenever a creature deals damage to you with a natural or manufactured weapon, it’s wielder takes 1d8 + Constitution modifier damage.
Corrupted: Most common in Koroblin/human hybrids as much as your body tries to hold itself together, it begins to warp in impossible ways. Your broken mind takes a -4 to Wisdom, but your form frightens and unnerves others, giving you a +4 to Intimidate. Creatures that begin their turn adjacent to you must make a Will save DC of 10 + half your hit dice + Charisma modifier or be shaken until the start of their next turn.
Monstrous: Your body warps to become more bestial in certain aspects as your body in a final effort of self-preservation. Your primal mind takes a -4 penalty to Intelligence, however you gain scent and get a +4 bonus to Perception. You also gain a +2 natural armor bonus as you are covered in fur, scales, thicker skin, etc.
