SpellbookMerge VS TabletopTweaks-Core

If you're on PC, there's a Spellbook Merge mod which adds a ton of new combos, which should also increase spell slots. The mod hasn't been updated since March, though, so caveat emptor; neither the mod author nor I accept responsibility if it bricks your game, opens a hell portal, etc. :)

Doesn't let you merge everything with anything but: https://github.com/vikigenius/SpellbookMerge

Spellbook merging is a big part of what makes an Angel Crusader KC so good. It's not an option for Warpriests unless you use this mod which adds Aeon+Warpriest merging.

If you got mods, may as well grab Mythic Spellbook Merge to merge anything. Be super busted with a whole new mythic path.

First, there is a mod that dramatically increases available spellbook merges if that's your primary concern. Gives all (early) mythic paths the ability to merge with a fair number of classes, highly recommend for absolutely everyone. Full disclosure, I'm not totally sure what you're on about with the archetype for MT and I don't understand how merging mythic into MT (assuming it affects both books) is anywhere remotely near balanced at all, but feel free to use toybox to give yourself whatever CL/DC/etc you'd like to mess with.

Here is the link.

If you're open to running mods, SpellbookMerge lets Angel merge with Paladin (and arcane classes). While it still doesn't reach the raw casting ability of Oracle/Cleric, Paladin is a classic divine beatstick class, and there's even the whole Radiance thing that incentivizes paladins. If longswords aren't exciting, there's also GreatRadiance that can make it into any other weapon type.

FYI there's also a mod which adds extra spellbook merging options. [Usual caveats about using mods at your own risk etc.]

Also, if you're on PC and feel like the spellbook merging options are too restrictive there's always this option, though some of the books would be extremely broken if merged.

Based on Pathfinder 1e, albeit with a lot of omissions and modifications. FYI there are mods to add features and bring it closer to PnP such as Tabletop Tweaks.

Tabletop Tweaks has four components: the main Core mod which acts as the foundation; then the subcomponents (Base, Reworks, Flanking) which are built on top of TTT Core. There's also third-party addons listed separately. Upside to this modularity is you only need to install the features you want; downside is each component has to be updated separately.

A Skald MC can take Azata path for Aivu; or Improved Mythic Trick (Lore Religion) for Animal domain. For a Skald mercenary or Companion, though, you're SOL unless you either use Toybox to enable Mythic Paths for other characters (which is buggy so YMMV whether it even works); or you install Tabletop Tweaks for Animal Ally feat. I used TTT to give Regill a mount that way.

I'm using Tabletop Tweaks to play a Crusader cleric of Erastil. With Deadeye's Blessing, I get WIS to hit with longbows without dipping Zen Archer so I don't delay my spells and benefit from spellbook merging. [Still need DEX for some ranged feats, though, so it's not a total dump stat.] Basically the idea is to focus on buff spells and ranged DPS for the first two Acts, then shift into a more caster-focused role later on with archery as a backup.

If you're using mods, Tabletop Tweaks adds the Animal Ally feat. Why settle for conventional pet classes when you can have, say, pure halfling Mutation Warrior on a leopard? Go crazy!
