Drow ArachnomancerMedium humanoid (drow)
Fey Ancestry. The drow has advantage on saving throws against being charmed, and magic can’t put the drow to sleep.
Spellcasting. The drow arachnomancer uses Divinity (Cha) to cast spells (spell save Difficulty 16, +8 to hit with spell attacks). It has 12 mana, a mana limit of 2, regains all expended mana when it finishes a long rest and regains half its total mana when it finishes a short rest. It knows the following spells:
1 mana: confusion poison, darkness, detect poison, envenomed weapon, faerie fire, fear, invisibility, levitate (self only), poison burst, protection from poison, putrefy food and drink, ray of sickness, slowing poison, toxic fumes
2 mana: bloodlust, call animal (spiders only), cloudkill, dispel magic, halo of spores, insanity mist, insect plague, mind control, neutralize poison, noxious plume, paralytic poison, poison bane, stasis, stinking cloud, web
Spider Climb. The drow can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Sunlight Sensitivity. While in sunlight, the drow has disadvantage on attack rolls, as well as on Perception checks that rely on sight.
Web Walker. The drow ignores movement restrictions caused by webbing.
Poisonous Touch (Humanoid form only). Melee Weapon Attack: +8 to hit, reach 1 m. Hit: 31 (8d6 + 3) poison damage. The first poisonous touch that hits each round deals an extra 26 (4d12) poison damage to the target.
Bite (Giant Spider form only). Melee Weapon Attack: +8 to hit, reach 1 m. Hit: 12 (2d8 + 3) piercing damage, and the target must make a Difficulty 15 Fortitude saving throw, taking 26 (4d12) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 health, the target is stable but poisoned for 1 hour, even after regaining health, and is paralyzed while poisoned in this way. The first bite that hits each round deals an extra 26 (4d12) poison damage to the target.
Web (Giant Spider form only; Recharge 5–6). Ranged Weapon Attack: +8 to hit, range 3/10 m. Hit: The target is restrained by webbing. As an action, the restrained target can make a Difficulty 15 Brawn check, bursting the webbing on a success. The webbing can also be attacked and destroyed (10 Defense; 5 Health; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).
Change Shape (Recharges after a Short or Long Rest). The drow can magically polymorph into a giant spider, remaining in that form for up to 1 hour. It can revert to its true form on its turn (no action required). Its statistics, other than its size, are the same in each form. It can speak and cast spells while in giant spider form. Any equipment it is wearing or carrying in humanoid form melds into the giant spider form. It can’t activate, use, wield, or otherwise benefit from any of its equipment. It reverts to its humanoid form if it dies.
No concoctions, maneuvers, or spells
All creatures in this system should have maneuvers or spells. You should add some maneuvers or spells to this creature. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all creatures via https://github.com/mlenser/kryx-rpg-issues/issues/9.
