In this video guide I will show you how to defeat the Blade Bearer and Connoeer in the Crypt Spire. This fight will be a real pain since you have to deal with two bosses at the same time. For this fight I
highly recommend that you have either the elemental resistance to all elements. Or have the fire and ice element resistances on. These will help a ton in negating damage from the bosses and help you survive. Other helpful spells would be Cleansing Light and Hasten. I also recommend using the assassin's sickle for the Cannoeer and a single handed sword for the Blade Bearer. It seems to match up better for the types of enemies they are. I also used Ios for the fight, but Yakumo would work as well. One other thing I would recommend doing is that you need to try and keep one boss on your partner and one on you. If the other one attacks you, go ahead and fight it. If they are both attacking you, one will eventually attack your partner. Just don't let your partner take them both on at once.
They both have pretty much the same moves, but opposite elements.
They both have a AOE move that they will cast around them when too close. Cannoeer has an ability where he will summon fire underneath you. Blade Bearer will cast some ice projectiles at you from a distance. Cannoeer has a flamethrower move he will spray fire at you. While he also has a flame punch with some basic slow moving punches with stomps.
The
Blade Bearer has some ice crystals she will summon from the ground at you. While she has some ice blade moves with some quick strikes. Not to mention she has some charging abilities also. The achievement will pop once they are defeated.
