Dante

Dante is a playable character added in Revelations Chapter Two. He is a two-in-one type character, with Charon being his second part.

Dante
Dante is the character the player spawns as, and is the main character of the two. Dante has ink tears, which leave slowing creep where they land. When beginning to fire, Dante will slam a book on the ground, which knocks back enemies and applies an increase of damage taken to enemies hit by the book (2.5x more damage if Dante is alone, 1.5x damage if he is merged with Charon). If an enemy collides with a wall as a result of the knockback, they sustain damage based on the player's damage-per-second rate. Enemies effected by the debuff will be tinted red and will have a red sigil above them. When used, the book will be on cooldown for two seconds, but will recharge instantly once a debuffed enemy is killed.

Charon
Charon is the secondary character to Dante. Phylactery works uniquely with Charon as it also serves as a passive item. If Charon keeps face the same direction, his shot speed will be increased. If he changes direction, hit shot speed will be cut in half. Charon will regain 33% of his shot speed if he keeps facing the same direction for two seconds, and the remaining 66% if he keeps facing the same direction for seven seconds.

Playstyle
When beginning a floor, Dante will spawn alone in the starting room, with Charon placed near the end of the floor. When Phylactery is fully charged (after clearing one room) all doors will be chained shut (excluding special rooms like the Treasure Room, Shop, etc.) Using Phylactery here will swap the player to the other character. The player must traverse through the floor with both Dante and Charon, with the goal being for the two characters to meet up in the same room. When both Charon and Dante enter the same room, their health, items, and trinkets will combine into one character. The player now controls Dante, with Charon now becoming a familiar-like entity next to Dante. Charon fires tears only in the direction he is facing. Phylactery will turn into a zero-charge active item, which is used to swap the direction in which Charon fires by activating it and pressing the firing keys (or movement keys, configurable in the Revelation's Options Menu) in the direction the player wants Charon to face.
