Skills

Skill 1

Tactical Grenade

Auto AttackCD: 1.75sLv.1 required

0★: Throws a grenade at enemies, dealing damage equal to 127.16% ATK and reducing their movement speed.

5★: Throws a grenade at enemies, dealing damage equal to 317.9% ATK and reducing their movement speed.

Damage between Pincers, plus a slow with no printed percent. 1.75s is slower than Conan’s 1.1s spear. 10,096 attack keeps this as filler.

Star upgrades
1★	Deals 25% more damage.
2★	Bonus damage is increased to 40%.
3★	Bonus damage is increased to 75%.
4★	Bonus damage is increased to 105%.
5★	Bonus damage is increased to 155%.

Skill 2

Pincer Tactic

Active SkillCD: 9.2sLv.5 required

0★: Employs the Pincer Tactic, reducing front-row allies’ damage from monsters by 168.675% for 6s.

5★: Employs the Pincer Tactic, reducing front-row allies’ damage from monsters by 295.1812% for 6s.

This is the team button. Front-row allies only, monsters only. Stars stretch the window to 8s / 9s / 10s and add extra monster DR (2% then 4%). It does not hit enemies. Raise this first for campaign.

Star upgrades
1★	Increases duration to 8 second(s).
2★	Takes 2% less damage from monsters.
3★	Increases duration to 9 second(s).
4★	Increases bonus effect to 4%.
5★	Increases duration to 10 second(s).

Skill 3

Zombie Nemesis

Passive SkillLv.21 required

0★: In combat, reduces damage from monsters by 27.25%.

5★: In combat, reduces damage from monsters by 27.25%.

Personal monster DR. The printed line stays 27.25%; stars add more on top. Same job as Conan’s Athlete. Blank against players.

Star upgrades
1★	Takes 2% less damage from monsters.
2★	Increases bonus effect to 4%.
3★	Increases bonus effect to 6%.
4★	Increases bonus effect to 8%.
5★	Increases bonus effect to 10%.

Skill 4

Wasteland Wanderer

Ace SkillLv.31 required

0★: Increases ATK, DEF, and HP by 10%.

5★: Increases ATK, DEF, and HP by 10%.

Personal capstone. Unlocks at level 31 and 4★. The printed line does not change from 0★ to 5★. Unlock it for the 10% stats. Pincer already covers the front.

Best for / not for

Pick him on monster maps when the front is the row that dies. Pincer Tactic is a front-row monster shield (168.675% at 0★, 295.1812% at 5★, 10s at 5★). 547,413 HP is fourth of 12, so he can stand near that row.

Team

Pincer names front-row allies, so put HP there: Zara, Toxina, Conan. Medium camp with Vera and Vince. A back-row sniper does not receive Pincer. Jack can sit Medium; the buff still goes to the front.

Zombie Nemesis is personal. One of Jack, Conan, Toxina, or Zara plus real damage is enough monster DR. Do not stack all four as the whole march.

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
Tactical Grenade	199,500	199,500
Pincer Tactic	199,500	199,500
Zombie Nemesis	199,500	199,500
Wasteland Wanderer	199,500	199,500

Pincer Tactic first: the front-row monster line is the kit. Tactical Grenade second: 1.75s filler and the slow. Zombie Nemesis third on campaign. Wasteland Wanderer last, at level 31 and 4★. Both book columns read 199,500.

Weaknesses

10,096 attack, ninth of 12. Not a carry.
Pincer and Nemesis do nothing to players.

Best role

PvPPoorPoor. Both monster skills are blank. Grenade still throws.
BossGoodGood if the boss counts as a monster. Pincer plus Nemesis.
ArenaPoorPoor. Same as PvP.
CampaignExcellentExcellent. This is the kit.
SupportPrimaryPrimary on monster maps. Pincer is the ally button.

Verdict

Raise Jack for Warrior or Tactical monster fronts that need a team shield, not for Arena. Star Pincer Tactic, take Wasteland Wanderer at 31 and 4★ for the 10% stats, and put HP in the front so the line has targets. Do not raise him to out-hit Celeste. If the week is players only, Conan’s anthem is the Tactical you wanted.
