[@Raijinslayer] True. 

[@EnterTheHero] Portals aren't an item, they're a power. Lapis's wings aren't a power since not only are they permanent but they also come from her gem. On top of that, when her gem was cracked Lapis could still use her water powers but couldn't summon her wings. Therefore, they are most likely unconnected.

[@BrassOtter] Neither does Bismuth. The argument here though is that Bismuth hasn't gotten enough air time to showcase her weapon (Altough it may be her hammer hands) and Peridot probably doesn't know she has a weapon, she didn't even know she had powers at first.
