This is pretty good, but I have a question, will you make a separate tome for the eldritch invocations cause if so that would be hella cool.
Alan Venic has quickly become my favorite publisher on DMsGuild and has the most consistant, well balanced arcetypes I have seen.
This collection of archetypes makes for a welcome addition to the Warlock's core options even though they are not as lacking as those of the Sorcerer.
