86J BOSS FROG. This room is illuminated by phosphorescent fungi growing on the cave walls, giving off a bright yellow-green light. The near pool is freshwater and holds Batrachus Versicolor, a monstrous wangateur. Maia the mermaid inhabits the far saltwater pool, manacled by a wrist to the wall.
Batrachus Versicolor, Froglodyte Wangateur (AC 4; MV 12”//15”; HD 7+3; hp 38; #AT 2 claws and 1 bite or 1 weapon; D 1-6/1-6/1-10 or by weapon +5 to damage due to strength of 18/94; SA Spit killer frog, steam breath for 2d8, chant; Size L; XP 1205)
Batrachus is about as bulky as a hill giant. As a special ability he can spit a glob of foul mucous, which will turn into a killer frog when it hits the floor. He can do so once per round, instead of a bite attack or steam breath but in addition to his normal claw attacks. He is not armed.
Killer Frog (AC 8; MV 6”//12”; HD 1+4; #AT 2 claws and 1 bite; D 1-2/1-2/2-5; SA Jump, surprise on 1-4; XP 36 + 2/hp)
Maia the Mermaid (AC 7; 1+1; hp 8; #AT 1; D By weapon; SA Sing; SD Take double damage from flame; XP 81)
Maia is a special mermaid princess and her singing can aid those she wishes to. When singing, anyone she is singing for attacks at +3 on to hit rolls and do +1 damage. Batrachus has, through threat and punishment, trained to her to sing to benefit him. If Batrachus loses one half of his hit points in damage, she will gain hope and start singing for his opponents instead, an act which will infuriate Batrachus immeasurably. Maia also has the special ability to control barracuda, if she encounters any within the salt mere, they will serve her faithfully. If Batrachus is defeated, Maia will hope to be taken to the ocean (many miles to the east) and set free. She is afraid of the salt mere and the terrible creatures that inhabit it.
Batrachus is infatuated by Maia (love is not an emotion that froglodytes' possess) and has heaped treasure about her pool: 10,987 gold crescents, 8 pearls worth 1000 gold crescent base value, seven silver cups worth 125 fold crescents each, and a cloak of the manta ray.
