If you're asking if the battle is hard, then it mostly depends on what class and companions you use. When I did this battle I was able to teleport to Deacon right at the start of it, because I have a Witchdoctor spell which allows me to. Also, I can take off roughly half of his health with only two spells (Mojo Blades) so that helped. I recommend the use of Musketeers or Witchdoctor companions because they don't need to be right next to Deacon to attack him, trust me when I say that trying to using a Buccaneer to go through the ever-growing crowd of Deacon's Henchmen is not the way to go. Remember, you and your companions and/or Henchmen (you buy these with crowns to help you during the battle) can be attacked tons of times per round, so make sure you pick ones with high health and good attacks. I ended up purchasing a Henchmen for this battle because my companions couldn't even make it to Deacon because of the massive crowd of Armada fighters. Whatever you do, don't let these guys scare you, you just got to keep fighting and eventually it will pay off. Don't be discouraged if you get defeated the first time, just heal and teleport back before the 30-minute timer runs out (or else you have to do the whole dungeon over again). I wish you the best of luck in this battle, and if you need any help just tell me!
The final battle with Deacon is in Cool Ranch, Haunted Skyway in Motherlode Mine I think it was. He can be difficult even if you did sidequests, just focus on taking him down, there isn't allot of point in dealing with the minions, unless they are blocking your way
Me in the final battle. Run to the cannon Shoot out spike trap The robots does not take damage from spike trap but disappear when it step on it. ( what?!)(bug?) The boss didn't move inches the whole long time. Beat most of the robots. More come (aw man)
Now you feel my pain
P.s one-eye jack why is the spike trap don't work on these robot and kept disappearing when they step on them?
I've been reading these replies, I'm in Haunted Skyway right now. Not even close to Motherlode Mine yet. I have a lot of Musketeer companions I like, so I'll go with one Swashbuckler, like me, and a Musketeer and Witchdoctor.
Hopefully they can do ranged attacks on Deacon while me and my Swashie companion take out the Armada troops. And, yes, it is in Cool Ranch.
