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: Prerequisite: 15th level
You can cast Invisibility at will, without expending a spell slot.
A creature you touch becomes invisible until the spell ends. Anything the target is wearing or carrying is invisible as long as it is on the target's person. The spell ends for a target that attacks or casts a spell.
Prerequisite: 7th level, Hex spell or a warlock feature that curses
Your curse creates a temporary bond between you and your target. As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see within 5 feet of the target cursed by your Hex spell or by a warlock feature of yours, such as Hexblade's Curse and Sign of Ill Omen. To teleport in this way, you must be able to see the cursed target.
Prerequisite: Pact of the Talisman feature
When the wearer of your talisman is hit by an attacker you can see within 30 feet of you, you can use your reaction to deal psychic damage to the attacker equal to your proficiency bonus and push it up to 10 feet away from the talisman's wearer.
