Meh.
Don't care about the Wizard.
I was really looking forward to the Warlock, but I was disappointed. They needed some new pacts boons, not patrons.
I have mixed emotions about the invocations; yes, it's great to see some new ones. Some look really good. Trouble is- the gatekeeping on them. I don't mind gatekeeping by level, or even a prerequisite of another invocation, but almost all of these are done by patron (or patron/pact). Which is ... of limited utility.
If they are going that route, then they might consider making invocations akin to a "spell list" by patron.
Underwhelmed.
Let's get serious here: who
honestly thought that there would be new Pact Boons? Like it or not, Patrons are the defining subclass mechanic for Warlocks and there's really not much, if any, cognitive grounds for new Pact Boons to incorporate. We've got a magical weapon, a spellbook, and a familiar. Like I keep asking, what's left? Much as I adored the Deadlands Hexslinger (don't judge me), really, it's a Pact of the Blade Warlock with a Gun as its Pact Weapon.
As for the gatekeeping on the new Invocations, honestly, I think it looks great; we've plenty of generic invocations in the corebook, but these really go a long way towards helping different warlocks with the same Pact or Patron feel unique. Thumbs up.
Mixed feelings on the new Patrons. The Hexblade is actually pretty awesome, as it expertly compliments the Blade Pact, but the Raven Queen is a little bit too... I don't know, specific.
The Loremaster is actually a lot better than I was anticipating; this actually feels like a pretty solid "generalist" tradition for mages, which we kind of gave up after the corebook release.
