惑星OWANDALの邪悪な強敵 Trophy in VVVtunia
How to unlock 惑星OWANDALの邪悪な強敵[The Wicked Formidable Foe of Planet OWANDAL]
[Defeated the formidable foe of Planet OWANDAL.]
For this trophy, you must clear the end-boss of Planet OWANDAL a second time. Notably, the boss will be stronger than it was last time and will have a different color scheme. Unlike the previous bosses, this one actually has a different point of access and most importantly, you will need the six key items from the maintenance area of not only the five previous dungeons but Planet OWANDAL as well.
While traversing dungeons for the first time, you may have noticed that there are areas that have a maintenance wall blocking them. If you contact these walls after clearing the dungeon for the first time, you will be able to break them like you would an open barrier gate and get to the other side. From here, you will be able to access a new entrance that leads to the room with the key item in a purple chest. While these rooms tend to have a higher number of barriers to activate than normal, these should give little trouble and you shouldn't have much issue getting each key item.
As for where to find each maintenance gate, they can be found in the following areas of each dungeon.
Planet OWANDAL: ???3rd (Can only be accessed after collecting the other five key items)
Once you have gotten the first five keys, go through the maintenance room of Planet OWANDAL (??? 0) to collect the sixth key item and then access the entrance to the stronger boss from here. There will be a save point and a warp point right at this area just in case you need to go back or you want to challenge successive tiers of this boss afterwards.
Once you finally get to access the room, just beat the two phases of Planet OWANDAL's endboss again and you will have the trophy. As usual, make sure that you have a character with a high TKMK stat to fill the heart on the second phase more quickly (I recommend Neptune for this as she has a high rate of fire and the highest natural TKMK stat).
