Way of the Web Warrior

One night, during your travels, a spider imbued with some sort of arcane blessing (or curse), bit you, and in doing so changed your biology and imbued you with a new set of powers, the abilities of a spider.

 

Wall-Crawler

At 3rd level, small hairs have grown on your fingertips, allowing you to stick to any surface. You can cast Spider-Climb as a bonus action without using a spell slot. You can then dispel the effects at will. You can use this ability 4 times per long rest at 3rd level. This number increases to 7 uses at 5th level, 10 uses at 8th level, and 13 uses at 11th level.

Web-Slinger

Also at 3rd level, your body has undergone a slight mutation, allowing you to produce web sacs akin to a spider that fire from beneath your skin near your wrists. You can use your action (attack) to shoot web-ropes at an enemy, and attempt to hit them with it. These are as finesse weapons, and do 1d6 bludgeoning damage, but also count as monk weapons. The webs have a range of 60 feet. If you hit your target, you can spend your bonus action to attempt to pull the creature towards you. The creature must make a Dexterity saving throw against your Ki Save DC, or he pulled at most 10 feet towards you. Alternatively, you can use your bonus action to spend 2 ki points to restrain the creature after a successful hit with your webs. The creature must make a Dexterity saving throw against your Ki Save DC. On a failed save, the creature is incapacitated for 1 hour, after which point the webbing dissolves.

When using them for travel, they have a range of 100 feet, and you can attempt an Acrobatics check with advantage to swing into the air, with your speed being equal to your movement speed.You can continue to do this to reach your destination. You can also use them to descend from ceilings, and can climb them, with the same rules applying. Any other creature that attempts to use them has disadvantage on the roll.

Spider Reflexes

Starting at 6th level, you can reflexively escape danger and attacks. You can now use your reaction to spend 1 ki point to Dodge after an attack is declared, but before the outcome is decided. Also, if an attack misses, you can use your reaction to move up to 10 feet away, either on ground or onto the floor or ceiling. This movement does not evoke opportunity attacks.

Spider-Sense

At 11th level, you now can sense when you are in danger, and are able to quickly react to it. Your Deflect Missiles feat now applies to melee attacks as well, and if the attack is made with a weapon (not an unarmed strike), and you deplete the damage to 0 points, you can spend 1 ki point to attempt to disarm your enemy by making an Acrobatics check against the creature’s Strength saving throw. If you succeed, you can throw it away from them, or spend 1 additional ki point to make an attack with the weapon, with disadvantage.

Amazing Spider-Monk

You have honed your abilities as a Web Warrior, and now, whenever you make an attack with your webs, you can restrain a target without spending ki points. Additionally, you can use the Wall-Crawler ability and unlimited number of times. Additionally, your strength has greatly improved. You now have advantage on strength checks and saving throws, and on attack rolls using your monk weapons (including unarmed strikes). You may also now substitute your Dexterity modifier for your Strength modifier.
