The Mystic Spearhand is more or less a “support” class that can provide beneficial effects for your party of Pawns.
I had roughly an hour and a half to spend with the Mystic Spearhand Vocation in Dragon’s Dogma 2, which gave me a taste of some of its skills.
Naturally with Dragon’s Dogma 2, Capcom expanded on this system with the addition of the Mystic Spearhand, an entirely new vocation that makes use of a spear.
I found the Mystic Spearhand’s strengths to be in providing support to your Pawns, which puts the Vocation in a strange position in Dragon’s Dogma 2.
