Role Summary[edit]

Name	PVE	PVP	PVE	Offense	Defense	Tournament
Cu Chulainn			C	D	D	D
Pros	65% damage boosters and 2 MP discount for random/AoE attacks, plus decent STR and MAG stats, let him work as a strong generalist in Democalypse. Force Pierce in Purple and Phys Pierce on Panel 4 let him function as a Force or Phys attacker outside of that. Impressive Phys damage with Gae Bulg, combined with 100% crit rate from Savage Glee and panels. He outdamages a max-invested P4 Mara, even if Gae Bulg rolls only 4 hits or fails to crit. Effective for BoS Deceit 14, as enemies there will only take damage from random Phys/Almighty attacks, which Gae Bulg happens to be. He's more stable than Mara for this, since Mara tends to waste Charge on normal attack. Cu's high crit also gives a good chance of crit-passing if he uses normal attack. A whopping 100% accuracy in his panel 4 (140% if you're attacking with maxed out Gae Bulg). No weaknesses is a lifesaver early on, and gives him more flexibility in transfer skills. Cheap to fuse through 4x4 fusions.
Cons	High MP costs. Cannot use Mazandyne or Gae Bulg Turn 1 in PvP unless Panel 3. Phys builds are not viable until panel 4, as he lacks Phys Pierce until then, and his low AGI and LUK means his accuracy is poor without P4's accuracy boost. No Single-Target attack means he will have trouble against Anti-Pierce and in PvP in general. Transferring a single-target skill does not fix the issue, as his innate damage boosters only affect random/AoE-targeting attacks. Does nowhere near enough reliable damage to have a role in modern PvP.
Notes	Low AGI makes him usable in Intimidating Stance teams. You can build into PATK or MATK, but not both simultaneously. For a phys + force build, consider building into PATK and transferring Rending Wind. Vorpal Blade is a good transfer for a Phys AoE build. Buffed during the 6/5/25 Data Update.

PvE Builds[edit]

PvP Builds[edit]

Concentrate PvP Offense Slow Team Build
	Transferred Skills		Notes: Going second in PvP and wearing Divine Brands gives Cu Chulainn exactly enough MP to cast a 6 MP Concentrate on his first action and a 7 MP Mazandyne on his second. This build is also effective in PvE content as well. (If you don't have Force Amp, Force Boost is an acceptable substitute.)
	Concentrate	Force Amp
	Infused Mitama
	Ma 20 Vi 20
Brands
Divine/Life and Ward with MATK% primaries.
Target Stats

Physical Sniper!
	Transferred Skills		Notes: With the current meta of very dodgy units, his 100% accuracy can come in real handy to counter said units. When fully paneled, Vorpal Blade will only cost 5 mp, making it very spammable. Gae Bulg will also cost 5 mp and could definitely work for pvp in cases where there arent many enemies left on the field as its 50 base power per hit and the 45% crit rate from Savage Glee and panel 1 means he will hit hard. Increasing his accuracy further with brands will make him even more overkill. Rebellion can be useful if youre up against stacked crit resistance.
