some gemsonas for me + my friends:

opalized fossil: can detach its head and throw/kick it around as a weapon, prefers a more animal-like form

amber: i havent asked em about air weapon but i was thinking they could be bombs, but filled with a sticky/gooey substance to trap enemies (like tree sap)

chrysoberyl: gem is in the back of her head and she can "see" anything she's looking for at that given moment (like garnets future vision but restricted to the present, and she can only see things she can recognise/has seen before) she's a brawler with a pair of horns as her weapon

pink quartz: team healer and has a bow for her weapon, magical girl aesthetic (her hair looks nicer from the back bc its made of hearts and i need to fix it)

woo!!

(edit: o ya i changed my gemsona bc every time i chose a gem they make a canon one on the show o my god)
