No matter what patron they serve, a huge part of the Warlock class in Dungeons and Dragons is the Eldritch Invocations. From offering a player the chance to give themselves extra life, to an extra attack, to making their cantrips supercharged, Eldritch Invocations are one of the main identifying features of the class. Warlocks can sometimes struggle at lower levels, feeling limited in their casting ability. However, as these Invocations are unlocked, the class fleshes out massively and becomes one of the most versatile at the table.
