I am on Rune Knight Job Change Quest. I progress till the final test of the quest. The final test requires me to defeat 3 monsters in a row. The 3 monsters are Executioner, Augurtus (a modified version of Ogretooth) and Mysteltainn.
I can not defeat the 3 monsters, because they are too high level. I found out that using the runes given by the quest npc does not work. Augurtus will immediately stun if I use Millenium Shield. The furthest I progress is using normal attack with all the supportive skills of Lord Knight and Knight to fight them, and able to kill the first 2 monsters, but no hp left.
How to defeat the 3 monsters?
