Unlocking Guardian
You unlock Guardian after defeating Revenant in chapter 4.
Equipment Guide
Guardian has S rank in Spears, and S rank in all armor.
Armor
Heavy armor is the way to go, since this class is best suited for tanking and you get the full benefits for wearing heavy armor. Definitely put a shield in your off hand, unless you are trying a damage dealing Guardian. Accessories that increase HP or Defense, are useful.
Weapons
Spears are what you want to go with since it is the only S rank. You will also want multiple support skills, so there is no room for those that raise you to S rank in another weapon.
Ability List
The specialty for Guardian is Guardian Spirit.
Guardian Spirit - Gain the ability to accumulate soul power, which can be spent on certain abilities. Soul Power will rise by 25% for each attack sustained, up to a maximum of 100%.
Level 1
Possession - Transfer your P. Atk, M. Atk, HP, MP, and Soul Power and take control of your target for 6 turns. Max HP, MP, and Soul Power will also be increased. Also clears a number of statuses and will lead to a game over if all other party members are K. O. or Ghosts.
Level 2
Soul Smash - Consume 20% soul power to unleash a powerful attack on the target that does 1. 5x damage.
Level 3
Soul Boost (Support Skill. Cost: 1) - Begin each battle with Soul Power already at 50%. Does not apply to successive battles.
Level 4
Soul Blaster - Consume 50% Soul Power to unleash a powerful physical attack on all targets that does 1. 5x damage.

Level 10
Soul Cannon - Consume 100% Soul Power to unleash a powerful physical attack on the target that does 8x damage.
Level 11
Twin Souls (Support Skill. Cost: 1) - Gain access to both characters’ abilities when possessing or being possessed by another character. Abilities cannot be used if you did not unlock them already.
Cross Job Tips
Exorcist is great for a side Job because you can just Undo HP when you aren’t using a soul ability to keep teammates at full health. Templar is probably the best to have just for the support abilities. Fortitude is great since you gain an extra BP while Defaulting. BP Limit Up is great so you can reach a max of 4 BP. Kaiser is nice if you want an extra BP for everyone every 4 turns, but it also applies to enemies. Knight is good if you want to dual wield shields for extra defense. Valkyrie is good if you want to deal damage and since both use spears, they work well with each other.
Combat Tips
Guardian is best used as a Tank, to take all the damage from enemies. It is helpful to have another character, or an ability of your own, that can raise the chance that enemies will target you.
Soul Mirror is great for stopping physical attacks, even though it can only be used on 1 person. This is useful for yourself or others. If people are more likely to target you, putting it on yourself has a higher chance of activating.
It can also help to put it on another member who has low defense to help them in case they do get targeted, or from multi-target attacks.
Possession or Possessed is great for offense and defense. You can take out enemies, or increase your own power by using it on them. You can also save a teammate from dying by possessing them.
