Shingi sent a message to everyone, letting them know of the creature heading toward them. They had recruited An into their party the other day to communicate with her through the chat function.
Shingi and Little Phoenix cast their INVISIBILITY Spell at everyone to hide, except Syra, who could conceal herself. Casting INVISIBILITY was expensive, and keeping it active for a long time also added to the amount of mana needed, especially when using it on so many people. But Shingi, who had most of the party targeted with his Spell, had enough mana to keep the Spell active for quite some time.
They all used their STEALTH Skill even if at some wouldn't make much of a difference, but any help would be helpful.
