Delita - Full Spirit Support Build by Kataikou

Introduction
So you just pulled a Delita and you've finished staring blankly at the ceiling contemplating your life choices. Though I'm sure you were hoping for one of the highly coveted 5* units, maybe a part of you might be trying to make the best of the situation. Although Moonblade is certainly a very nice trust mastery reward, it would be much nicer to put Delita to work.

Luckily for us, Delita's ability awakenings shot his power through the roof. While initial impressions on his upgraded breaks amounted to a hard "no", the global exclusive adjustments put him into a niche yet powerful position as an offensive support.

This build aims to maximize Delita's utility as an offensive support unit, primarily focused on his Helm Break and Shield Break while giving him additional options through Meditate and Cura by maximizing his SPR stat. With this build, Delita can:
 * 1) Increase your party's damage by 185% on vulnerable targets
 * 2) Recover 35-40 mp per turn,
 * 3) Heal 1200-1500 hp with Cura, almost 3000 hp with dualcast.
 * 4) Massive Healing through healing items
 * 5) Provide additional utility through Esper and Ability Materia.

Helm Break/Shield Break
Any Delita build will focus on using Helm Break and Shield Break. They are simply the best DEF/SPR breaks in the game right now. We were all pleasantly surprised when Delita's enhancements gave him an extra 5% to his breaks in Global, amounting to a 35% additional damage, giving the team an unmatched total of 185% increase in damage.

Here's a comparison of Delita's breaks against common breaks found in the game.

Delita wins by a large margin. Not only is the break the best in the game, but also lasts the longest. This gives him plenty of extra turns to buff, debuff, and heal.

Helm/Shield Break will almost always be the first thing you use in a battle, and often you will only need one or the other based on your team composition. The few times you'll want to use both in a single battle is if you have a mixed physical/magic damage team, or you want a bit more damage out of your hybrid damage dealers.

Meditate
Meditate, Delita's other signature ability, comes in the form of a beefed up Focus. A party wide 65% MAG/SPR buff for 5 turns is certainly nothing to scoff at, especially if there's a decent amount of magic damage on either team. Awakened, the skill grants a party wide buff that recovers (20 MP + 0.5x) over 5 turns. Scaled with your SPR stat, Meditate has the potential of healing 35 to 40 per turn for 5 turns. Here's a table with expected recovery numbers:

Meditate has the benefit of having a relatively high modifier for mp recovery skills, as well as a very long duration. Other MP Skills, such as Ling's Invigorating Dance and Ace's Spirit Hand, require recasting every turn for its effect. Noctis's Cover (FFXV) lasts only 3 turns and recovers MP with a lower modifier, but compensates with an included HP regeneration (though a SPR build on a Noctis is very rare).

It appears that the MAG/SPR buff is applied before the MP Recovery buff, so take that into account if you are aiming for a target MP per turn. It amounts to a difference of 3-4 mp, but that can be an important difference.

Equip: Rikku's Pouch
Rikku's Pouch is a fantastic addition to Delita's kit as it gives him three additional spells to his arsenal:
 * Panacea
 * Cures all status ailments to all allies. Incredibly useful ability, and takes the pressure off your healer to cast Esunaga or some other equivalent ability.
 * Eccentrick
 * Increase LB gauge fill rate (200%) for 5 turns to all allies. Another 5-turn buff that fits into Delita's kit perfectly. Very useful if you happen to have units who benefit greatly from using their Limit Bursts (Y'shtola, Cecil, Olive, Zyrus, Kelsus, etc).
 * Chaos Grenade
 * 30% Break to ATK/DEF/MAG/SPR to all enemies, inflict random status ailments, and does a bit of damage. The break is a little redudant, but gives Delita access to ATK/MAG breaks. Definitely useful against battles with multiple enemies. You probably won't use this much.

Equip: Healer's Wisdom
Items got a huge buff with the addition of two things: Ilias's Healer's Wisdom and Expedition items.

Healer's Wisdom doubles the effectiveness of healing items, and they stack additively (NOTE: Needs Confirmation), so a second would give you 3x item effectiveness, a third will give you 4x, and a fourth will give you 5x. The Expedition items gives access to AoE heals and MP recovery. Putting these two together results in massive amounts of healing.

Of course, you also have access to Potion of Elemental Resistance, Potion of Cleansing, and other useful items. As you can see, having 4x Healer's Wisdom is a bit overkill. Unless you plan on side-healing using items exclusively, slotting in a Dualcast is likely more beneficial.

Equip: Pod 153
Oh buddy, Pod 153 is a great TM. If you're fortunate enough to get one a 9S from the Nier Automata banner, then you've got one of the best abilities for Delita. Because Delita has plenty of extra turns in his turn rotation, he's able to use the extra abilities from Pod 153 very efficiently. It's unfortunate that Nier Automata is a limited banner, but if you missed it then consider voting for 9S on a player's choice banner. There's also a small chance of another Nier event when they bring A2 Steak Sauce over to JP servers.
 * A120: Repair is a 3 turn party regen that's essentially a Curaga.
 * A060: P Shield is a 40% physical party damage mitigation, which supplements meditate nicely since you don't have a DEF buff in your kit.
 * R020: Mirage is useful, but it's unlikely you'll make use it, though, as you won't use it every turn and your ATK stat isn't very high.

Baseline Equipment
Since Delita's Breaks don't require any equipment, we'll be focusing on maximizing the effect of Meditate. As such, this build will focus on optimizing his SPR stat. From there, we can adjust the build to suit the situation by swapping in relevant equipment or materia to give Delita some additional utility between refreshes.

The first item in this baseline is the best-in-slot item you can that is NOT part of a limited event or 5* character Trust Mastery Reward. The alternative choices may include limited items and are marked as such. The baselines only cover improving stats. Equipment for additional utility is in the next section.

Key
 * World-Vortex.png Obtained from a limited Event.
 * Rarity-5.png Obtained from a Trust Mastery Reward from a 5* base unit.

Alternate Builds
1-TM Budget=

If you have an Equip Staff from Roselia, and have gathered enough Y'Shtola TMs from the raid event, you can build a decent amount of SPR on the cheap. Expect to recover about 32 mp a turn, and heal 1250 hp with cura with this setup. Of course, you can beef this up with event exclusive equipment.

Another option is to give him Healing Staff as a source for Cura. This allows you to use a different Esper in place of Carbuncle.

Thanks /u/WayneJarvis_ for the suggestion.
