Warlocks choose the invocations they learn as they gain levels, much like bards or sorcerers choose which spells to learn. However, a warlock’s arcane repertoire is even more limited than that of a sorcerer, and his invocations are spelllike abilities, not spells. In addition to its grade (least, lesser, greater, or dark), every invocation has a spell level equivalent, which is used in the calculation of save DCs and for other purposes. A least invocation has a level equivalent of 1st or 2nd; a lesser, 3rd or 4th; a greater, 5th or 6th; and a dark invocation has a level equivalent of 6th or higher (maximum 9th). The level equivalent for each invocation is given in its description.
A warlock can dismiss any invocation as a standard action, just as a wizard can dismiss a spell. Invocations and Eldritch Blast: Eldritch blast is not an invocation, but some invocations provide a warlock with the ability to modify his eldritch blast or add new eldritch attacks.
Eldritch Essence Invocations
Some of a warlock’s invocations, such as frightful blast, modify the damage or other effects of the warlock’s eldritch blast. These are called eldritch essence invocations. Unless noted otherwise, eldritch blasts modified by eldritch essence invocations deal damage normally in addition to imparting the effects described in the invocation description. A warlock can apply only one eldritch essence invocation to a single eldritch blast, choosing from any of the eldritch essence invocations that he knows.
When a warlock applies an eldritch essence invocation to his eldritch blast, the spell level equivalent of the modified blast is equal to the spelllevel of the eldritch blast or of the eldritch essence invocation,
whichever is higher. If a warlock targets a creature with an eldritch essence blast that has immunity to the invocation’s effect, it still takes the damage from the blast normally (provided it isn’t also immune to the eldritch blast).
A warlock can apply an eldritch essence invocation and a blast shape invocation (see below) to the same blast. When a warlock uses both kinds of invocations to alter an eldritch blast, the spell level equivalent is equal to the spell level of the eldritch blast, the level of the eldritch essence invocation, or the level of the blast shape invocation, whichever is higher.
Blast Shape Invocations
Some of a warlock’s invocations, such as eldritch spear, modify the range, target(s), or area of a warlock’s eldritch blast. These are called blast shape invocations. Unless noted otherwise, eldritch blasts subject to blast shape invocations deal damage normally in addition to imparting the effects described in the invocation description. A warlock can apply only one blast shape at a time to an eldritch blast, and he can choose from any of the blast shape invocations that he knows. A warlock need not apply a blast shape invocation to his eldritch blast. When a warlock applies a blast shape invocation to his eldritch
blast, the spell-level equivalent is equal to the spell level of the eldritch blast or of the blast shape invocation, whichever is higher.
A warlock can apply a blast shape invocation and an eldritch essence invocation (see Eldritch Essence Invocations above) to the same blast. When a warlock uses an eldritch essence and a blast shape to alter an eldritch blast, the spell-level equivalent is equal to the spell level of the eldritch blast, the
eldritch essence invocation, or the blast shape invocation, whichever is higher.
