Well, it was mentioned by you just a few posts back with an image from the monster girl encyclopedia... so it kinda was a given.
As for gaining something, regain health for starters. But thinking about it, the same way we are (usually) given a choice about how to sex certain npc/enemies, with a high mantis racial score and being female or herm with marked feminine features (breasts, face...), the option to eat the male is offered. To make it more of a choice for those that might enjoy it, for example it could be made that if you indulge too much on the eating the male part, a counter goes up (like on the shark girls bad end, you rape too much, you get bad ended) and when a certain threshold is reached, the PC becomes a feral raping and eating mantis to be met by the next champion and perhaps tempt him/her much in the same way the mantis npc did to them?
Well yeah I could jsut forshadow mantis-girl npc or just using pic to explain faster than trying to write wall of text hiw I wanted mantis morphs to looks like.
Interesting idae about high mantis score at female PC. SO in survival mode eating would restore quite much hunger comparible to drinking dose of milk of some npc's. And I quite much like idea for bad end with been too much mantis-like especialy for PC's with female bits.
Tonight I won't work more on mode so will share some effects of last hours.
You began your journey as a human, but gave that up as you explored the dangers of this realm. You are a 5 foot 6 inch tall female mantis-morph, with a slightly wide frame that displays your curves and has hints of muscle underneath.
You are currently wearing your glistening gel-armor plates, comfortable bra and comfortable panties and using your dragon rapier as a weapon and buckler as your shield. Your face is human in shape and structure, with olive skin. It has a beautiful, feminine shapeliness that’s sure to draw the attention of males. The long, orange hair on your head is parted by a pair of cute pointed ears, bigger than your old human ones.
You have a humanoid shape with the usual torso, arms, hands, and fingers. A pair of large mantis-wings sprout from your back, reflecting the light through their clear membranes beautifully. They flap quickly, allowing you to easily hover in place or fly. Shining green exoskeleton covers your arms from the biceps down with a long and sharp scythes extending from the wrists. You have flared hips that make you walk with a sexy, swinging gait, and your substantial butt fills out your clothing nicely. A large insectile mantis-abdomen dangles from just above your backside, bobbing with its own weight as you shift. It is covered in hard greenish chitinous material. Your two legs are covered in a shimmering green, insectile carapace up to mid-thigh, looking more like a set of 'fuck-me-boots' than exoskeleton.
Still not done all body parts that will showing up in appearance screen nor all stats changes or bonuses for high enough racial score. So I would say Blade Grass item is around 50% completed atm.
