New stuff.
Aspect of the Moon (tome): Good utility if your not an elf.
Cloak of Flies: ???
??? (blade): ???
???
???
??? (chain): ???
Improved Pact Weapon (blade pact): This helps blades out damage eldrich blast. If just a little. Worth much less if you have a magic weapon.
Grasp of Hadar (eldritch blast): Nice at-will control, but warlocks generally don't want to pull enemies closer. Can be combined with repelling blast and a zone (cloud of daggers, wall of fire) to push someone out, and pull back in, forcing them to take the zone damage a second time.
Lance of Lethargy (eldritch blast): Yet another control option for eldritch blast. Combines nicely with repelling blast, to keep enemies away.
Maddening Hex: Nice damage when you get it, but fades pretty quick. And given that hex also uses bonus actions, you won't get a lot of use out of it. You also probably won't be using hex as your spell against hordes. Ok for hexblades, but still not great.
Relentless Hex: ???
???
Tomb of Levistus: ???
Tricksters Escape: Generally not needed unless your DM really likes grappling monsters and capturing you. At least it doesn't take a spell slot.
Maybe more on the next page.
