Spell-Less Warlock Redesign

[noob]

Eldritch blast feature needs better wording. As it is currently written, I can cast eldritch blast while tied up and gagged.

Here is how I would write the feature.

Eldritch Blast
A beam of crackling energy streaks toward a creature within 120ft. Use your action to make a ranged spell attack against the target. On a hit, the target takes 1d10+Charisma modifier force damage. You must have at least one hand free and the ability to speak to use this ability.

Your Eldritch Blast creates more than one beam when you reach higher Warlock levels: two beams at 5th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.

no need to state the use of charisma for the attack roll. The Warlock’s Spellcasting Ability says what to use.

I may not be seeing the bigger picture, so what I wrote maybe completely wrong.

What?
You are supposed to not be able to blast while tied and gagged?
So how do superheroes gets out of their bindings?
(ps: tons of superheroes are just like warlocks and are best simulated with warlocks)
