This combination turned out to be the “big kahuna” in this book, with each combination of pact boon and bonded artifact type meriting its own feat. There’s a lot of natural synergy between the two classes, both of which use points-based spellcasting and getting the casting abilities lined up is trivially easy. They also both have at least the potential to mix combat and spellcasting capabilities. Getting their signature features interwoven with the first couple of synergy feats completes what should feel like a very natural merge. A stronger focus on warlock levels will make the character more magical in their capabilities, with a larger pool of spell points to draw on and more powerful eldritch blast, using a less-powerful artifact that is still useful. A higher concentration of wielder levels makes for a more combat-focused character with a powerful artifact that is still a bit weaker than that possessed by a single-classed wielder and some more magical features, and an even mix will also work out perfectly fine with a moderate-high level of magic, solid combat capabilities and a middling artifact. This very much feels like a combination that is near-impossible to mess up and yet is profoundly versatile in the way it can be built. Bear in mind that it is also possible to acquire two of the “capstone” feats by using the Pactkeeper’s Reward invocation if that is desirable.
