During the Hatching Tide Event: The Spells that the Spriggans used although similar in name, they looked different than the normal spells. They had more of a FF'ish feel to them. The Ice was a large ice block, the fire was a flame. The lightning was wider. Was this the effects team testing out what the spells are going to look like?
For those that haven't had the pleasure of seeing the Moderator/NPC that appears at the camps at random times. They give you cool buffs, similar to Bubble. Boosting HP/MP values. There is also a buff to increase movement speed (lasts for like 3 mins).
It gives an idea of the things that are lying in wait that have been produced but not yet released. Really cool IMO
