Prerequisites: 5th level, Pact of the Blade

Prerequisites: 5th level, hex spell or a warlock feature that curses
As a bonus action, you cause a psychic disturbance around the target cursed by your hex spell or by a warlock feature of yours, such as Hexblade's Curse or Sign of Ill Omen. When you do so, you deal psychic damage to the cursed target and each creature of your choice that you can see within 5 feet of it. The psychic damage equals your Charisma modifier (minimum of 1 damage). To use this invocation, you must be able to see the cursed target, and it must be within 30 feet of you.

Prerequisite: 5th level
As a bonus action, you can surround yourself with a magical aura that looks like buzzing flies. The aura extends 5 feet from you in every direction, but not through total cover. It lasts until you're incapacitated or you dismiss it as a bonus action.
The aura grants you advantage on Charisma (Intimidation) checks but disadvantage on all other Charisma checks. Any other creature that starts its turn in the aura takes poison damage equal to your Charisma modifier (minimum of 0 damage).
Once you use this invocation, you can't use it again until you finish a short or long rest.

Prerequisite: 5th level
You can breathe underwater, and you gain a swimming speed equal to your walking speed.
You can also cast water breathing once without expending a spell slot. You regain the ability to do so when you finish a long rest.
(This spell grants up to ten willing creatures you can see within range [30 ft] the ability to breathe underwater until the spell ends in 24 hours. Affected creatures also retain their normal mode of respiration.)

Prerequisite: 5th level
As a reaction when you take damage, you can entomb yourself in ice, which melts away at the end of your next turn. You gain 10 temporary hit points per warlock level, which take as much of the triggering damage as possible. Immediately after you take the damage, you gain vulnerability to fire damage, your speed is reduced to 0, and you are incapacitated. These effects, including any remaining temporary hit points, all end when the ice melts.
Once you use this invocation, you can't use it again until you finish a short or long rest.

Prerequisite: Pact of the Blade
You can use any weapon you summon with your Pact of the Blade feature as a spellcasting focus for your warlock spells.
In addition, the weapon gains a +1 bonus to its attack and damage rolls, unless it is a magic weapon that already has a bonus to those rolls.
Finally, the weapon you conjure can be a shortbow, longbow, light crossbow, or heavy crossbow.
