Rashield is Zatch's second spell, gained after their first encounter with Reycom and Hosokawa. It summons a tall, wide electrical wall to defend against frontal attacks by deflecting the attack and charging with with electricity to do additional damage.
The spell can guard at best mid-level spells, but after its enhancement during the battle with Faudo, it is shown to easily be able to guard against Gigano-class spells. If Zagurzem is used on it, the strength of the shield increases.
It is used by Zeon only in the video games.
