Skills

Skill 1

Heavy Revolver

Auto AttackCD: 1.35sLv.1 required

0★: Attacks enemies with a revolver, dealing damage equal to 106% ATK.

5★: Attacks enemies with a revolver, dealing damage equal to 392.2% ATK.

He is not empty while Hawkeye is down. 1.35s, 106% ATK at 0★, 392.2% at 5★, on 22,050 attack. That is a support auto, not a carry auto. It does not buff allies.

Star upgrades
1★	Deals 35% more damage.
2★	Bonus damage is increased to 75%.
3★	Bonus damage is increased to 130%.
4★	Bonus damage is increased to 190%.
5★	Bonus damage is increased to 265%.

Skill 2

Hawkeye

Active SkillCD: 12.3sLv.5 required

0★: Sends a falcon to scout the battlefield, increasing all allies’ ATK by 10.8% for 6s.

5★: Sends a falcon to scout the battlefield, increasing all allies’ ATK by 16.8% for 8s.

This is the skill. All allies, 10.8% ATK for 6s at 0★, 16.8% for 8s at 5★, 12.3s cooldown. Duration is 7s at 1★ and 8s at 4★. 2★ adds 10% Crit Rate. Raise this first. It does not deal damage.

Star upgrades
1★	Increases duration to 7 second(s).
2★	Increases Crit Rate by 10%.
3★	Increases ATK by 3%.
4★	Increases duration to 8 second(s).
5★	Increases ATK Boost to 6%.

Skill 3

Sheriff

Passive SkillLv.21 required

0★: In combat, increases Skill Cooldown Speed by 15.3% and reduces damage taken by the ally with the highest ATK by 7.2%.

5★: In combat, increases Skill Cooldown Speed by 30.3% and reduces damage taken by the ally with the highest ATK by 12.2%.

Two jobs. His own cooldown speed, 15.3% at 0★ to 30.3% at 5★, so Hawkeye comes back faster. Damage taken down on the ally with the highest ATK, 7.2% to 12.2%. If Lucian (26,726), Yana (25,850), or Monroe (25,343) is in the march, Sheriff points at them, not at Carter’s 22,050.

Star upgrades
1★	Increases Skill Cooldown by 3% and reduces incoming damage by 1%.
2★	Increases bonus effect to 6% and 2%.
3★	Increases bonus effect to 9% and 3%.
4★	Increases bonus effect to 12% and 4%.
5★	Increases bonus effect to 15% and 5%.

Skill 4

Doomsday Judgment

Ace SkillLv.31 required

0★: Increases ATK, DEF, and HP by 20%. Increases Skill Cooldown Speed by 20%.

5★: Increases ATK, DEF, and HP by 20%. Increases Skill Cooldown Speed by 20%.

Personal capstone. Unlocks at level 31 and 4★. The printed line does not change from 0★ to 5★. Unlock it for 20% ATK, DEF, and HP plus 20% skill cooldown speed. The cooldown line stacks with Sheriff’s personal cooldown speed.

Overview

Carter is the UR Heavy Assault who buffs the march instead of carrying it. Heavy Revolver is a 1.35s auto. Hawkeye raises all allies’ ATK by 10.8% for 6s at 0★ and 16.8% for 8s at 5★. Sheriff raises his skill cooldown speed and cuts damage taken by the ally with the highest ATK. Doomsday Judgment unlocks at level 31 and 4★: 20% ATK, DEF, and HP, plus 20% skill cooldown speed.

At Lv.150 / 5★ he has 486,558 HP and 22,050 attack. HP is 7th among the 15 URs. Attack is 9th. Power is 7th at 757,742. Summon: 10 fragments.

Best for / not for

Pick him in marches that already have a real attack column. Hawkeye is 16.8% ATK for all allies for 8s at 5★. Sheriff cuts 12.2% damage taken on the highest-ATK ally. Seat Lucian, Yana, or Monroe so that line has a target.

Skip him as a damage UR. 22,050 attack is 9th of 15 and will not win a burst check against Lucian (26,726), Yana (25,850), or Monroe (25,343). Skip him as the tank: 486,558 HP is 7th, still about half of Bekka (992,082).

Team

Hawkeye names all allies. Sheriff names the ally with the highest ATK. Put the damage URs in the march: Lucian 26,726, Yana 25,850, Monroe 25,343. Carter’s 22,050 should not be the highest ATK in that lineup, so Sheriff does not land on him. Heavy camp. He does not name a front or back row.

Investment

Skill books are the sum of the per-level costs in the game data. Use the hero calculator for EXP and fragments.

Skill	Books to Lv.30	Books to Lv.40
Heavy Revolver	226,000	576,000
Hawkeye	226,000	576,000
Sheriff	226,000	576,000
Doomsday Judgment	226,000	576,000

Hawkeye first: 16.8% ATK for all allies for 8s at 5★ is the reason to own him. Sheriff second: 30.3% cooldown speed and 12.2% damage cut on the highest-ATK ally. Heavy Revolver third: the 1.35s auto on 22,050 attack. Doomsday Judgment last, at level 31 and 4★.

Strengths

Hawkeye is 16.8% ATK for all allies for 8s at 5★.
Sheriff cuts 12.2% damage taken on the highest-ATK ally at 5★.
486,558 HP is 7th among URs, enough to cast.

Weaknesses

22,050 attack is 9th of 15; not a carry column.
Hawkeye’s 12.3s cooldown is longer than the 8s buff at 5★, so the ATK is not up the whole fight.

Best role

PvPGoodGood. All-ally ATK plus a guard on the carry.
BossGoodGood. Hawkeye feeds the highest-ATK damage dealer.
ArenaGoodGood. Same as PvP.
CampaignGoodGood. The buff does not care about monster flags.
SupportPrimaryPrimary. This is the job.

Verdict

Raise Carter when the march already has Lucian, Yana, or Monroe and you want an all-ally ATK chant plus a shield on that carry. Star Hawkeye first, then Sheriff. Take Doomsday Judgment at level 31 and 4★ for the 20% stats. Do not gear him as the damage UR; 22,050 attack is not that column.
