Gunbreaker: they are the other expert tank, they specialize in physical damage reduction. They use lots of small, long general cooldowns (along with some phys-focused one) and regens as their playstyle is split into two phases: a more tank focus phase where you’ll apply said mitigation and a DPS-focused phase where your Continuation combo can’t be interrupted, so you’ll have to time your mits and heals beforehand or risk losing most of your damage.

White Mage: White mage is your starter healer with simple but most powerful and direct healing and offensive spells. MP managment and positioning are key since all WHM spells are more expensive than other healers’ and they have the longest cast times as well, with Glare and Holy leaving no weave windows normally. At higher levels can gain different types of Lilies to cast istant and free magic (both healing and offensive) and they can enter an amplifier stance that’ll greatly increase the MP cost of their offensive spells for even more damage. WHM has the potential to top the charts of healer damage with proper MP managment and stance dancing, but overhealing and greed will quickly drain you of mana if you’re not careful.

Astrologian: Astrologians combine time magic and rng to make a mixed healer/offensive support. They have selected powerful heals that need to be timed precisely and long regens, along with a costant stream of cards to play to buff their allies. As such, it has the least DPS tools and personal damage but more than makes up for it in terms of rDPS.
The Major Arcana features one of 6 cards:
Bole: applies a small shield that reflects back part of damage absorbed if broken
Ewer: bulk MP recovery + increased MP recovery over time
Arrow: doubles auto attack speed and halves cast time of spells
Spire: reduces recast time of all skills currently on cooldown
Balance: increased luck (crit and proc chance)
Spear: haste (increased skill and spell speed)
The Minor Arcana consists of a random Lady or Lord of the Crown, but they also features 2 more cards as oGCD: Refresh, that resets the timer of a Major Arcana buff, and spread, that extends the current buff of major arcana of a player to all players. It’s a high AMP job as cards will be coming out fast and you’ll have timed heals and bombs to manage as well, so spells will have shorter cast times than WHM and Lightspeed will be essential. Although your personal offensive kit is limited, Astrologian can also multiply the damage done by a party in a certain amount of time through Foresight, that’ll place a timed “damage shield” on an enemy that if reached will increase the damage done (think of it as Wildifre but you need to deal x amount of damage in order to activate).
