I now have all three crowns from the DLC. I used player summons to help with the Fume Knight and the Ivory King. Both, even with player summons were good fights. The Ivory King fight kind of represents the entirety of the DLC as if you do it right you end up with a gang war.
I still haven’t beat 4 bosses from the three DLC’s. I was invaded three times trying to get to the Blue Smelter Demon and the I haven’t even found the third boss in the final DLC.
Before I quit I am going to try to beat the Smelter and Sir Alonne. Maybe I will give the gank squad another try.
