Similar to the Prisoner, the Confessor is essentially a "jack of all trades, master of none" class that is versatile and capable of being built in a variety of viable ways. From stats to weapons and armor, here's a class guide on the Confessor in Elden Ring.
Confessor Elden Ring Class Guide: Stats
Off rip, the Confessor has truly one of the most well-rounded base stats, with Faith being the strongest at 14. Stating the game at Level 10, are in an ideal position to access some of the most powerful Faith-based abilities relatively early on, but can also simply be a good starting point for those not totally sure what playstyle and particular weapons they want to use yet.
Ultimately, the most important stats for perhaps the best-optimized Confessor are Vigor for HP, Faith for sacred Incantations, Endurance for stamina and equip load and Strength in order to be able to use the best shields.
Confessor Elden Ring Class Guide: Weapons
The Confessor starts players off pretty conveniently with a Finger Seal and a Broadsword, which can easily be made stronger when modded with an Ashes of War to provide a special ability that buffs the stats of the player and their summons. As such, you're pretty much set up right away to fight just as the class describes — both with a sword and incantations.
Confessor Elden Ring Class Guide: Armor
With the Confessor, you're not locked into any particular style of armor, but Light might be the best way to go as it allows you to roll faster and with slightly more frames of invincibility.
You will want to upgrade your Strength up from 12 to 16 right away, however, in order to be able to use the Brass Shield right away, which can easily be acquired early on into the game. The Brass Shield has also has 100% physical block, just like the Confessor's starting Blue Crest Heater Shield, but also has an added advantage of consuming less stamina thanks to its high Guard Boost Stats.
Elden Ring is available now for PlayStation 4, PS5, Xbox One, Xbox Series X|S, and Windows PC (via Steam).
