Sculk Stealing Player XP...

I had an idea just now for a new Sculk Mob/Block and this involves the Sculk stealing Player XP.
Now I know this may be a hit or miss but it adds some extra spice to Ancient Cities any new development for Anything Sculk.

I would imagine if this were to be a block it would work similar to a Catalyst but this time it would Steal Directly from a Player if activated and the method of Activation would be only through Sculk Sensors and players standing too close to this new block or standing on Sculk in general.
Now if it were a mob it would still probably need a functioning block to summon said mob but this particular side of the idea would have it were the mob would steal a very miniscule amount of XP on each hit dealt to the player.
I would imagine this mob would be the size and similar design to a Silverfish/Endermite, be slow when moving normally but can burrow within the Sculk to move much faster to catch up to the player.
This mob will do one heart of damage which isnt much but can also take a large amount of damage, this creature can also perform a similar attack like Spiders in which it can jump at players and can climb up natural blocks that generate within caves.

I would imagine this is a hit or miss to some players since it quite literally steals player XP and would be a tougher mob to kill but this mob is only to pose a threat within Ancient Cities and/or future Sculk biomes, and give a slight aid in players who are out of reach from the Warden without being too unfair.
