15. After you kill the first form, Ispita's second form will spawn, first in the lefthand square in the middle of the room, then it will jump to the right square ect...until you kill it. It hits just as hard as the first form but has a lot less defense. You cannot run through the barriers that pop up around it so you need to be inside the square in BM when it spawns. You have 30-35 seconds to kill it.
16. About 10 seconds after killing the second form, Ispita's final form will appear, this time surrounded by mobs. Kill the mobs and Ispita's final form. After you kill Ispita, click again on the lamp in Step 13 to continue.
17. There will be a long, poisoned hallway filled with mobs after Ispita's room. Dash through it until you come to the next room with a fountain like the first boss.
18. In the room you will find the boss Trugater, surrounded by more mobs that were by Ispita. Kill the mobs and the boss.
19. Click the panel shown in Trugater's room to break down the gate.
20. Beyond the gate are strong powerful mobs. Clear all of them to make it easier on your party later.
