FAIRY TAIL Wizard Chronicle Gray Guide: Best Builds and Teams for Gray Fullbuster & Devil Slayer
Gray is one of FAIRY TAIL Wizard Chronicle’s strongest ice‑type damage dealers, with Gray Fullbuster acting as a solid early bruiser and Gray Devil Slayer being a top‑tier late‑game carry. Both versions benefit from crit, defence‑shred, and control, but Devil Slayer in particular stands out for high DPS and boss performance.
Gray Fullbuster vs Gray Devil Slayer
Tier lists and videos broadly agree that Gray Fullbuster is good but outscaled, while Gray Devil Slayer sits among the very best UR damage dealers.
One written tier list calls UR Gray Fullbuster “decent damage output for a backrow unit” with freeze and defence‑break, but notes his slow attacks and late‑game drop‑off. By contrast, another tier list groups Gray Devil Slayer with Natsu Dragon Force, Wendy and Erza Heaven’s Wheel in the very top “cream of the crop” bracket.

Best builds for Gray Fullbuster & Devil Slayer
Both Grays are DPS‑leaning, so builds focus on ATK, crit, and making the most of their debuffs and control.
Stat priorities
| Priority | Gray Fullbuster (UR) | Gray Devil Slayer (UR) |
|---|---|---|
| 1 | ATK, Crit Rate | ATK, Crit Rate/Crit Damage |
| 2 | Skill/ultimate damage | Skill/ultimate damage, any talent that boosts boss DPS |
| 3 | Some HP/DEF so he survives as backliner | Some HP/DEF; he is still a DPS but must live through long boss fights |
TapScreen’s UR breakdown notes that Gray Fullbuster’s crits can apply a top‑tier defence decrease, and his ultimate deals big AoE damage plus a debuff, making Crit Rate particularly valuable. Gray Devil Slayer is described across guides as a premier DPS whose damage scales extremely well with offensive stats for bosses and advanced content.
Gear guidelines
| Slot | Gray Fullbuster | Gray Devil Slayer |
|---|---|---|
| Weapon | High ATK with Crit / skill damage subs | Same – ideally a UR weapon with ATK + Crit/Crit DMG |
| Armour | ATK‑leaning with some HP/DEF | Balanced ATK + bulk for survivability in tough content |
| Accessories | Crit, skill/ultimate boosts | Crit, boss/skill damage, and any ice/demon‑slayer‑flavoured boosts if available |
Beginner and tier guides recommend always equipping pieces that increase power on main carries (using the power arrow), then min–maxing crit and ATK on your best DPS like the Grays.
Best teams for Gray Fullbuster & Devil Slayer
Gray fits especially well into Blue‑heavy and mixed‑element teams as a primary or secondary carry.
Gray Devil Slayer core teams
High‑level best‑team breakdowns consistently show Gray Devil Slayer as one of the top picks for boss damage and high‑end PvE, usually paired with Erza HW, Wendy, and other S‑tier URs.
When to use Gray Fullbuster
Gray Fullbuster is most useful:
- Early to mid game, as a back‑row DPS/control unit when you do not yet have Devil Slayer.
- In teams that need extra freeze and defence‑break to support stronger carries like Natsu DF or Lucy Leo.
One release video places Gray Fullbuster in a mid tier, describing him as “reliable most of the time” with strong freeze and defence‑crush but slower performance, which matches the written B‑tier verdict. As your box improves, you should gradually shift investment from Fullbuster to Devil Slayer as your main Gray.
