While wearing a Mantis Helmet (done with chitin and football helmet), noticed that it didn't absorb any damage from attacks and remained in 100% (died because of that too, since it was a vampire bat attack). I don't know if it was made whether to be just a decorative item or not, but since it takes a football helmet, I guessed not (especially since the Mantis armor took damage similarly to a log suit but with more durability).
Steps to Reproduce
Make a mantis helmet, wear it, get attacked by any non-Charlie entity. Full damage taken by Wilson, helmet still at 100% with no damage absorbed.
