Get ロストドラゴン to appear

[bladesoframen]

For the 100% monster compendium, one of the hardest monsters to find is the ロストドラゴン. To get him to spawn, you have to fight a 竜術士, and make the AI think you're struggling. What this entailed for me was having 3 of my characters die and having my last character take a few thousand more damage each turn. If you do stall it out enough while taking damage, a 竜術士 will hopefully transform into a  ロストドラゴン. When it does appear, kill it, and the monster will be added to your compendium
