I did few FSC runs and I noticed, a few times when you're going against vanaduke after you do the second mask phase there's a chance that the deadnaughts wont spawn. At first(since it was my first time doing it in a while) I thought that they took out the deadnaughts spawning, so I did it the second time and I still prepared to kill them with the shiv, and then they still didn't spawn. Then the 3rd time I was for sure that they wouldn't spawn, I didn't do any preparation for them, and when the deadnaught's should've spawned they didn't. And then they spawned again like 5 seconds later and they surprised me and killed me. Has anyone else run into this glitch?
Deadnaught Spawning FSC
I don't know why Vanaduke sometimes skips the summoning, but it has been happening since 2011 (and probably during the game's beta phase too).

There actually is a reason. If you do damage to lord vanaduke in his invincibility phases and dash or use the shadow cloak there's a chance he won't spawn any of his minions or fire orbs making the fight much easier. It is, however, hard to pull of, since you need perfect timing. It's best done with pre set traps like drakon's firestorm or seraphinix's ray or tortogun charges or just any bomb. Just charge and dash just at the right time shortly before his invincibility phase ends and he won't spawn anything.
I've also tried hitting him through the shadow fore before the fight actually starts then dash before he begins to spawn his minions and just starts to attack me or turn around.
Sometimes, however, I've only delayed this behaviour rather than cancelling it. If you're solo and hou hit him then dash he'll just delay it by a few seconds.
If you can master his AI you can kinda break the fight making it extremely easy. I believe that very very few if none know this info. But those were my observations on the matter. I don't have any other info and would like tp research but IDK how.
Every time a different non mask phase begins, Vanaduke uses ( is meant to, that is )his summon skill. But sometimes he will try to attack a player imediatelly, cancelling the summon. Usually its because the player he " aggros " to first is on front of him so he attempts to use the mace slam.
