Shieldwarden

Shieldwardens are a healing class that walk a tight line between being too cautious and being too confident. Those too cautious will burn through their mana quickly, while those who wait too long before shielding may find their allies already on the floor where their shields will do little to get them back up. They lack traditional combat healing, but make up for it with superior numbers on their shields.

Power Word: Shield is their standard protection spell. You’ll want to cast it on your tank or the target most likely to get hit in the early rounds of combat.

Power Word: Barrier is also an option for an early cast, but the mana cost may feel high if the temporary HP doesn’t get used. Since it can be cast while using RP, it may be better to wait until the party is targeted by AoE attacks before using it.

Power Word: Reinforce is a manaless way to give your allies more shields, with the condition that you probably already placed shields on them beforehand. It also works with temporary HP not applied by you, so there’s some possible powerful synergies there.

Secret Art: Lifesaver is something you’ll only use as a last resort. Unless someone is low on hit points, it will not provide great value for its mana cost. But if you combine it with the above mentioned reinforce, an ally can fight at near death for a long period of time.

Recover Power makes it less likely you waste your mana by shielding yourself near the end of the combat, but it only works on yourself.
