One of today's Sunny Sunday perks is that when an elite monster spawns, a second elite monster spawns at the same time.
I saw this happen earlier while grinding in Black Heaven: Black Heaven Junction 1.
But while killing Corrupted Masters in Phantom Forest: Forgotten Path, Stormcaster Caeneus appeared alone.
I was able to complete a surprise mission to kill 3 elite monsters by killing him, so he does count as an elite monster.
I'm guessing it doesn't spawn 2 elites in Phantom Forest because the elites there aren't enlarged copies of regular monsters.
Is this intended behavior?
Edit: I've seen a rune of darkness properly spawn 3 elites before, and that 2 will appear with an elite boss.

Summary: Wielding a Crimson Arcglaive with NORMAL attack speed, my attacks are noticeably slower than they were before the v208 update. I don't actually know what else this may apply to, but there's already another thread complaining about a particular skill being slower. I think it's being caused by the same problem. forums.maplestory.nexon.net/discussion/25948/chaos-lock-considerably-slower-after-v-208-update
I'm sorry if this is counts as a duplicate report. I want to avert a case of them looking at that skill, seeing nothing wrong with it, and overlooking a root cause elsewhere.
