Wreckers do not chase. They put a line on a hull and let the sea do the rest. Malbrek fights the same way, and every instinct a party has about where to stand is the wrong one while the chain is out.
Thrown at the enemy standing FURTHEST away, out to 25m — the back line, not the person in his face.
The chain drags them bodily back to him for 3d8+6 with a Reflex save against being put on the ground. Running is the wrong move.
35% of it runs down the links into the held target instead, and heals him for the same. No prior mechanic in this bestiary shares damage between the boss and a player; focusing him is the wrong move too.
The line falls off, clean. Walking straight into the thing chaining you is the only way out — the inverse of every other positional puzzle here, which are all solved by getting away.
CR11, the batch apex and Goblin Coast's new ceiling, two notches over Barknuckle's CR9 and level with Ilqaeth. Everything under him on the coast is CR9 or lower and the trash caps at CR6, so he is the one fight there that a party genuinely has to be ready for.
He is the bestiary's first Lasher. Fighter 5 / Lasher 6 carries the class's real whip feat chain (Lashing Whip, Improved Disarm, Improved Knockdown), and the blueprint carries a real whip — gc4_chain, cloned from PRC's own whip blueprint for the correct model parts with every item property stripped, so his damage comes from his statistics and his mechanic rather than from a magic weapon a CR11 kill would drop.
The tether releases cleanly on his death, on the held target's death, and on an area transition, so it cannot strand a leftover flag on a player.
No spells, no epic spell — a martial prestige class at CR11.
