Ablilites
Saraya possesses standard Gem abilities, including weapon summoning, shape-shifting, bubbling, regeneration,Cluster, agelessness, and superhuman strength/durability.

She appears to have telekinetic abilities. In addition, she seems to have extreme tolerance towards pain. This is explained and justified due to the fact that she is a Cluster of two gems. Out of all of the Gems, it is clear that Saraya is the strongest physically, but just how strong is currently unknown.
