The invocations and pact boons are interesting ideas, those are good. Some of the invocations seem a bit powerful but I'm not expert, and the two pact boons are simple but sensible additions to pact boons. The ideas for the patrons are there and I do like the ideas. They're creative. My only problem with them personally is that unlike many other class options I've found here on DM's Guild the patrons here are remixes of existing Patrons from the Player's Handbook and the Unearthed Arcana. In other words, for example the Ascendant's 14th level ability is an altered version of the Fiend's Hurl through Hell ability, changed slightly to be appropriate to a demigod as opposed to a demon lord. But for the price point listed that's completely acceptable. Aside from that this is a reasonable supplement.
