Base Class: Cleric
Cleric of lolth
Bonus Proficiency
When you choose this domain at 1st level, you gain proficiency with heavy armor and martial weapons
Wrath of the Spider
Also at 1st level, you can rebuke attackers. When a creature within 5 feet of you that you can see hits you with an attack, you can use your reaction to cause the creature to make a Dexterity saving throw. The creature takes 2d8 necrotic or thunder damage (your choice) on a failed saving throw, and half as much damage on a successful one.
You can use this feature a number of times equal to your Wisdom modifier (a minimum of once). You regain all expended uses when you finish a long rest.
Channel Divinity: Lolth’s blessing
Starting at 2nd level, you can use your Channel Divinity to wield the power of Lolth with unchecked ferocity.
When you roll necrotic or force damage, you can use your Channel Divinity to deal maximum damage, instead of rolling.
Triumphant Sorrow
you learn to harness the beauty in failure, finding inspiration in even the direst twists of fate. Whenever you or an ally within 30 feet of you rolls a 1 on the d20 for an attack roll, an ability check, or a saving throw, you can use your reaction to soliloquize and regain one expended use of your Channel Divinity feature.
Divine Strike
At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 necrotic damage to the target. When you reach 14th level, the extra damage increases to 2d8.
Avatar of Lolth
At 17th level, you gain resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks.
