My athletics proficiency says it can allow me to jump further than normal but the jumping rules don't state this anywhere.

He said that it seems really bad for later on usage if I want to keep it as my niche. He said find a way to scale it up with my character and he’ll see.

ITEM
———————————————————————————

You can expend charges in the following ways.
Spider-Swing. As a reaction when you fall, or as an action, you can expend one charge to produce a 50-foot line of silk webbing that can stick to any surface and lasts for 10 minutes, after which it crumbles into dust. It can be used to arrest a fall, climb a wall without a check, or grab an object. Space permitting, if you use this while falling, you can make a DC 15 Dexterity (Acrobatics) check to swing. On a successful check you return to the same height from which you fell (or 50 feet, whichever is less). On a failure, you continue to fall.

Web-Cluster. As an attack when you take the Attack or Ready action, you can expend a charge to make a ranged weapon attack (range 30/120 ft.) against a target. On a hit, the target must succeed on a Strength saving throw(DC = 8 + Proficiency Bonus + 1/2 Dex rounded down) DC 15, becoming restrained on a failure, or having its speed halved until the end of its next turn on a success. As an action, a creature can make a DC 15 Strength check, freeing a creature restrained in this way on a success.
