D&D 5E Strengthening Interception Fighting Style?

[Sword of Spirit]

Although I'm sticking with 2014 rules, I'm adopting a small number of 2024 rules, including the buff to Protection style...which just showcases how underwhelming Interception style's scaling is. Sure, at lower levels it's fine, but at higher levels it falls way behind.

Anyone have any ideas to keep Interception style relevant for higher levels? I've considered maybe adding your level rather than proficiency bonus to the damage blocked, but even that might not be enough.

I go with something close to the monk attack deflection: 1d10+Str or Con+level.

Personally:
When an ally within 15 feet of you is hit with an attack, you can use your Reaction to move to the nearest free adjacent space to your ally and reduce the damage by PBd6+CON. You need to holding a shield or a weapon to use this benefit, If you cannot reach an adjacent space the damage you reduce is halved.

basically this gives it a much greater catchment area as well as scalling the amount of damage it can block, the movement is IMO a zero-sum feature but is for the flavour

I’d have the damage reduction scale more as the character levels up. CreamCloud above has it scaling with Proficiency Bonus, and that would work. My solution would be to have it scale at the same pace cantrip damage does. So: 1d10 at level 1, 2d10 at level 5, 3d10 at level 11, 4d10 at level 17.
