Hello, it's Matsui.
Thank you for your feedback.
Because many of the posts here are talking about Delve, I wanted to make a few comments on what I've read.
First,
We check every day on the status of Delve boss monsters being defeated.
We know that the use of Stun is one of the main methods utilized to defeat these monsters.
As it is now, although there are three different Delve bosses, the number of defeats of Tojil is substantially higher than the other two. It seems that most players have adopted a method in which they avoid the majority of Tojil's damaging abilities by stunning them.
It is, of course, possible to defeat these monsters in other ways that do not use Stun as significantly, as boss monsters are designed to be defeated in multiple ways.
With specific regard to Tojil, I'll give some more information. Tojil is similar to Achuka from the Wildskeeper Reive, and is adjusted to be able to be defeated within Delve. Both Tojil and Achuka, as you may notice, will occasionally be cloaked in flames. When in this state, there are certain powerful techniques and higher ranked spells which are utilized that are not otherwise used. It is important during the defeat of the monster to clear this state.
Throughout this thread, there has been a lot of information on the behavior of boss monsters, so I'll introduce one of those posts:
I see a lot of people who are convinced that Stun is the only method of defeating these bosses. For the Morimar boss, there are things like Incinerating Lahar which can be completely avoided by ranged attackers and isn't used under certain conditions. The Foret boss has Marine Mayhem, which will always instantly kill people at a distance but only does damage to those close by. Also, even though the forest boss is water-based, it's designed so that it cannot always be Stunned. We will need to focus on other methods anyway, as I'm sure the Delve bosses corresponding to Lightning and Earth elements will not be stunnable.
To highlight one point, as the HP of boss monsters (including Tojil) is reduced or certain conditions are fulfilled, certain abilities replace other abilities, and it is important to note and plan for this when the boss is preparing to use a dangerous ability.
Since Delve fractures are easy to retry, please work on making gradual progress towards understanding the behaviors of the boss monsters. During this process, I believe that new methods of defeating these monsters will arise.
