Here's part Two of my SRD conversions, letters F through K. I'll post L-R tomorrow and then round it out on Wednesday with S-Z and some templates.
This post is open game content.
Frost worm look like white and blue purple worms. They are capable of burrowing through ice, but not stone. They can produce a sonic trill that causes creatures who fail a saving throw to stand stunned for the duration of the trilling. If attacked, a stunned creature may make another saving throw. The worm can breath a cone of cold once per hour that inflicts 10d6 points of damage (saving throw for half damage). When killed, the frost worm turns to ice and shatters, dealing 10d6 damage to all within 100 feet.
• Frost Worm: HD 14; AC 1 ; Atk 1 bite (3d6); Move 12 (Burrow 3); Save 3; CL/XP 18/3800; Special: Trill, breath weapon, explode, immune to cold.
A cruel hunter and roaming brigand, the fury is a harpy that has trained to become a deadly archer. Furies often become mercenaries, selling their services to the highest bidder. When not employed, they make ends meet as highway robbers, forcing merchant caravans to pay protection money. Their siren song is no less effective than a normal harpy’s, and their touch also charms (saving throws apply).
• Fury: HD 7; AC 4 ; Atk 2 talons (1d3) and weapon (1d6+2); Move 6 (Fly 18); Save 9; CL/XP 8/800; Special: Flight, siren-song, +2 to hit and damage with bows.
Ghosts are restless spirits that dwell between the ethereal and material planes. They can emit a frightening moan (save vs. fear) and their touch ages a person one decade (in the case of most humanoids) or one century (in the case of long-lived demi-humans). Ghosts can also use telekinesis to hurl small objects. As ethereal creatures, ghosts can only be harmed by magic spells and weapons.
• Ghost: HD 6; AC 4 ; Atk 1 touch (aging) or 1 hurled object (1d4); Move (Fly 12); Save 11; CL/XP 9/1100; Special: Moan, aging touch, telekinesis.
Girallons are 8-foot tall, albino, four-armed gorillas that are as strong as stone giants. Although capable of fighting with their claws and bite, girallons sometimes employ simple weapons in combat. They are tribal by nature and have a simple language. They are fond of gems, jewelry and shiny metal. They are also fond of human flesh. Girallons speak their own simple language. A girallon that hits with two or more claw attacks latches onto the opponent’s body and tears the flesh for double damage.
• Girallon: HD 7+1; AC 16; Atk 4 claw (1d6) and 1 bite (1d8); Move 15 (Climb 15); Save 9; CL/XP 7/600; Special: Rend with claws, track by scent.
Grimlocks are a race of subterranean humanoid that raid the surface world at night searching for humans to butcher and devour. They are completely blind, but with their highly developed senses of smell and hearing they can sense creatures within 20 ft. Although they are immune to spells that require their victims to have sight, they can be partially “blinded” with spells such as ghost sound and sound burst or substances like snuff. Grimlocks have grey skin, black hair and white eyes. Their teeth are large and sharp. Grimlocks speak their own language. Grimlocks sometimes (10%) lair with medusae. In rocky areas, grimlocks are effectively invisible (and require a see invisibility spell to detect) if they remain motionless.
• Grimlock: HD 2; AC 4 ; Atk 1 slam (1d6) or 1 weapon (1d8); Move 15; Save 11; CL/XP 4/120; Special: Blind-fight, invisible in rocky areas.
A howler looks like a massive, emaciated lion with a mane of quills. In the middle of the night, it lies low in the grass and howls for hours on end. Those who hear the howl must make a saving throw each hour or temporarily lose one point of wisdom, with creatures who lose all of their wisdom dropping dead. Creatures engaged in melee combat with a howler suffer 1d4 attacks each round from its quills. With each successful attack, the victim must make a saving throw or have the quill break free and lodge in their flesh. Each quill so lodged imposes a -1 penalty to hit in combat.
• Howler: HD 6; AC 5 ; Atk 1 bite (2d8), 1d4 quills (1d6); Move 24; Save 11; CL/XP 8/800; Special: Howl, quills.
Janni are lesser kin to the djinn and efreet. They are formed of all four elements, and thus dwell on the material plane. They can change a creature’s size twice per day, become invisible three times per day, and speak with animals at will. They can also create food and water once per day (as a cleric) and shift into the ethereal plane for a few rounds at a time. They have telepathy with a range of 100 feet. Most janni are encountered wearing chainmail and armed with a curved sword and longbow.
• Janni: HD 6; AC 3 ; Atk 1 weapon (1d8); Move 12 (Fly 15); Save 11; CL/XP 7/600; Special: Spells.
Kapoacinth are aquatic cousins of the terrestrial gargoyle that lack wings. I imagine their "skin" might look like coral, and they would perch on a reef waiting for an unlucky sahuagin or undine to swim past.
• Kapoacinth: HD 4; AC 5 ; Atk 2 claws (1d3), 1 bite (1d4), 1 horn (1d6); Move 9 (Fly 15); Save 13; CL/XP 5/240; Special: None.
The krenshar is a strange, catlike carnivore with extremely flexible skin on its head. Krenshars use solitary scouts to drive prey into the waiting clutches of the pride. The scout appears from hiding, uses its scare ability, then chases the fleeing target to join the attack. A krenshar can pull the skin back from its head, revealing the musculature and bony structures of its skull. Combining this with a loud screech produces an unsettling effect that works like a scare spell.
• Krenshar: HD 2+2; AC 4 ; Atk 2 claw (1d4) and 1 bite (1d6); Move 15; Save 16; CL/XP 3/60; Special: Frighten.
