Gene — The Encounter

armored great-white duelist fighting with paired cutlasses · a boss your table can run with almost no prep. SRD 5.1-compatible.

Who Is Gene

Where the rest of the reef-corsairs board with brute hunger, Gene boards with form. A great-white were-shark clad in salvaged plate, he learned the blade from a fencing-master he later ate, and he fights with a cutlass in each clawed hand, parrying and riposting before closing with his teeth. He takes a strange pride in clean kills and looks down on the crew's messier members, though he never refuses a share of the blood. Inchan sets Gene against armed officers and trained guards, the foes that would shrug off a wild bite, and trusts the duelist to cut them down with method while the pack handles the rest.

Blood Frenzy. Gene has advantage on melee attack rolls against any creature that doesn't have all its hit points.

Twin-Blade Flurry. When Gene takes the Attack action with his cutlasses, he can make one additional Cutlass attack as part of that action (already included in Multiattack).

Amphibious. Gene can breathe air and water.

Actions

Multiattack. Gene makes two Cutlass attacks and one Bite attack.

Cutlass. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 4) slashing damage.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

Bonus Actions & Reactions

Parry. Gene adds 3 to his AC against one melee attack that would hit him. To do so, he must see the attacker and be wielding a cutlass.

Gene fights like a swordmaster who happens to be a shark, two cutlasses weaving a steel cage before the jaws snap shut.

How It Fights — by Tier

Same creature, scaled threat. The traits never change; only the numbers move.

Tier 1Levels 1-4 · GUIDELINE
AC15HP45 (7d8+14) To-hit+4Save DC12

Single out the best-armed defender and trade blows, using Parry to weather their swings and Blood Frenzy once they bleed. Finish with the Bite. Pairs off against fighters while the pack handles the rest.

Tier 2Levels 5-10 · NATIVE
AC17HP110 (13d8+52) To-hit+7Save DC14

Lock down the party's martial threat: open with the cutlass flurry, Parry their counterattacks, and Bite when Blood Frenzy is online. He duels the dangerous foe so the other sharks can swarm the casters.

Tier 3Levels 11-15 · GUIDELINE
AC19HP176 (21d8+84) To-hit+9Save DC16

Fight as the warband's duelist: peel off and pin the toughest front-liner with relentless cutlass attacks and Parry, freeing the pack to flank. He excels one-on-one but still needs allies to win the field, never solo.

Questions, Asked at the Table

What CR is Gene?

He is a CR 6 (2,300 XP) Tier 2 elite at his native numbers, with Tier 1 (~CR 2) and Tier 3 (~CR 11) stat lines for scaling.

How does Gene fight alongside the rest of the Pirate Sharks?

He is the warband's duelist. Gene singles out the party's toughest martial fighter and ties them down with cutlass flurries and Parry, letting the rest of the sharks overwhelm the softer targets. He is a specialist, not a solo boss.

How often can Gene use Parry?

Once per round, as a reaction, while he can see the attacker and holds a cutlass. It adds 3 to his AC against that single melee attack.
