Aranamica

• Changes: An eye forms and opens somewhere on your body. Ever open but blind.
• Arachnid Traits:
  • Gain blindsight of 15ft that also extends on any type of nets or ropes.
  • Gain the ability to ignore difficult terrain and immunity to web spells or effects.
  • Spiders will regard you as an ally and not attack you.
• Innate Spellcasting:
  • Gain the ability to cast Spider Climb and Speak with Animals at will without material components.
  • Gain the ability to twice choose a spell to cast; Web or Gift of Alacrity. This ability recharges after a Long or Short Rest.
• Arachnomorph: As an action you may change shape into a spider creature of CR1 or lower and a size equal to the spider's size or smaller where you can add 3 hp per Hit Die. You can use this feature once per short or long rest. You can stay in a spider shape for up to two hours before you revert to your normal form. You can revert to your normal form earlier by using a bonus action on your turn. You automatically revert if you fall unconscious, drop to 0 hit points, or die. You may use Innate Spellcasting while in spider form. Except for the specifics here, this ability works like the druid's Wild Shape and a druid can use their Wild Shape uses for the Arachnomorph ability or the Arachnomorph shape change to perform a Wild Shape.
