OoC @Berk: "Jona cowered as the falling mech came to a halt just centimetres from his faceplate"
You made a typo there.
Envy was unable to twist the sword around, no matter how much force it applied. The sword would quicker bend then the keyhole would turn. As he 'commanded' the sword to use fire, nothing happened.
"Earth magic? No, I don't know that." Savranth called out to Data. Seeing Envy drop to one knee, Savranth rushed over to it using high speed movement magic. "Can you still stand?"
As more of Xyleena's acidic blood dripped on the mech, it began eating away at the plates at a faster rate, although it still happened slowly.
When Rex's electricity beam struck the mech, it was electrified, potentially electrocuting Grace and Xyleena.
When it was lifted up by Jona, the mech dispelled the ring of fire, and instead used earth magic to lift up a pillar of earth towards its feet. Now clear of any danger of being crushed, the mech aimed its tail at Jona and unleashed a blast of cold that would freeze anything in ita path, how much depending on the duration of the exposure. As this happened, the mech aimed three of its back-mounted laser turrets at Lyra, Data and Marcus, and fired.
