Giant Scorpion Fish
Giant scorpion fish are another matter. These six - foot-long fish view humanoids as potential prey, and usually attack by ambush. Although they do not attack with their spines, anyone making a melee attack against a giant scorpion fish must succeed in a DC 10 Reflex save to avoid contact with the fish’s spines, doing 1d3 damage and poisoning the unfortunate attacker with the scorpion fish’s venom. Extracting venom from a smaller scorpion fish is difficult (DC 20 Handle Poison yields a single dose), but 1d3 doses can be garnered from a larger fish and 1d3+3 from a giant scorpion fish with a DC 10 Handle Poison check.
Summary
Init -2; Atk bite +2 melee (1d6); AC 14; HD 3d6; MV swim 40’; Act 1d20; SP spines, venom (Fort DC 15; 1 Stamina on a success; 1d4 Stamina on a failure plus save again or 1d3 Agility), camouflage +6; SV Fort -8; Ref +4; Will +0; AL N. Most scorpion fish are no more than an inch or two long, but larger scorpion fish (1d8 + 35 inches) exist. These fish are not intentionally dangerous to humanoids, but are bottom -dwelling creatures in shallow brackish water or near coral reefs, where they may be stepped on or otherwise come into contact with unlucky adventurers. Scorpion fish typically make only a single, defensive, attack before attempting to disengage.
