Lifedrinker
Source: Player's Handbook
Prerequisite: 12th level, Pact of the Blade feature

When you hit a creature with your pact weapon, the creature takes extra necrotic damage equal to your Charisma modifier (minimum 1).

Quote
Thirsting Blade
Source: Player's Handbook
Prerequisite: 5th level, Pact of the Blade feature

You can attack with your pact weapon twice, instead of once, whenever you take the Attack action on your turn.

To clarify, a hexblade with the blade pact who takes the lifedrinker invocation adds charisma bonus to damage TWICE. A blade pact warlock of any other patron adds str or dex once (depending on weapon) and charisma once, provided they have the lifedrinker invocation.

2Xcharisma mod is fairly powerful, but it doesn't come online until level 12, so I think this is fine.

Also, I sincerely doubt that they are giving blade pact warlocks the thirsting blade invocation "for free". They will still have to pay for it with an invocation.

Well, it's part of pact of the blade now, though you have to be level 5. Basically, turns you into a martial. I do agree that Thirsting Blade will either be gone or do something else. More correctly, I think it'll be replaced by a new evocation with other features from hexblade and/or the rest of Hex Warrior. If you want the extra melee attack, just take pact of the blade.
