Warlock 2024 Vs 2024 Season. Advanced 5th edition games, plus new horde rules and rules for heroic. One is that chain pact joins the other pacts at 1st level, instead of 2nd.

Plus it is the only subclass with 7 subclass features. Below are all the changes to the 2024 warlock versus the 2014 warlock (notably, both still fall under the dnd 5e rules).
