Spider Champion

Although drow make up the bulk of spider champions, they are not the only ones who fear and respect spiders for their hunting prowess.  Wielding their poison, webs, and uncanny movement, you are a remorseless predator.

Arachnid Sorcery

At 3rd level, you know the spells Spider Climb andWeb.  You can cast both of them without components, although you can cast Spider Climb only on yourself.

You can cast both spells once.  If you do so, you can't again until you finish a long rest.  Intelligence is your spellcasting ability for these spells.

Spider Friend

At 3rd level, you can communicate with spiders as if you shared a common tongue.  You have advantage on Charisma checks made to influence them.

Spider Strike

Starting at 3rd level, you can imbue your blows with a spider's poison.  Once per turn, when you hit a creature with a weapon attack, you can deal an additional 1d4 poison damage.

Arachnid Companion

At 7th level, you learn the spell Find Familiar and can cast it without components.  The familiar summoned is always a spider.

You can cast it once.  If you do so, you can't again until you finish a long rest.

Improved Spider Strike

Beginning at 7th level, your poison is supernaturally potent.  Your Spider Strike now deals 1d4 + half your fighter level poison damage.  This damage ignores resistance and treats creatures immune to poison as if they instead had resistance.

Hunter's Leap

Starting at 10th level, you can perform great leaps like bird-eating spiders.  When you jump, you can triple your jumping distance.

Once you use this feature, you can't use it again until you finish a short or long rest.

Poison Immunity

At 10th level, you have spent so much time exuding poison that you are now immune to it.

Spider's Blessing

Starting at 15th level, you gain tremorsense with a range of 15 feet and can permanently climb walls and sheer surfaces as if affected by Spider Climb.  In addition, you cannot be trapped by webs and they are not difficult terrain for you.

As an action, you can choose any number of creatures you can see within 30 feet of you.  They gain the benefits of Spider's Blessing for 1 hour. 

Once you use this feature, you must finish a long rest before you can use it again.

Arachnid Surge

Starting at 18th level, when you use your Action Surge, you can activate one of the two following effects.

Summon Spiders.  You can instantly summon monstrous spiders with a combined total CR of 2 in unoccupied spaces within 30 feet of you.  You can choose among Giant Wolf Spider, Swarm of Insects (Spiders), and Giant Spider.  Summoned spiders' attacks count as magical for the purpose of overcoming resistance and immunity to nonmagical weapons.  The spiders act immediately on your turn and serve you loyally for 1 hour.

Web Blast.  You can instantly cast Web without any components.  An instantly cast spell doesn't take an action to cast. Casting it this way isn't a concentration spell.

Once you use this feature, you can't do so again until you finish a short or long rest.
