A terrifying adversary! The 3-4-3 alone makes this difficult to beat. But the effect is also debilitating to the Blessed Papa. The advanced version really needs to be dealt with before playing most of the bless seal cards and abilities that Father Mateo has. Otherwise Serpents of Yig truly makes it scary to play any bless cards, let alont he advanced The Codex of Ages. My way of dealing is to try to mulligan and even hard search for this enemy, letting my fellow investigators help me in defeating this monster :D Is nicely countered by Father Mateo's statline being boosted by whopping +1 on all skills.
