I've been working on this pdf on the homebrewery for a while and I need some feedback about whether or not the subclasses are unbalanced and suggestions.  All constructive criticism is appreciated, thank you!  Just ignore the printer prompt please.

Some really interesting ideas here! A few things:

Oath of the Hammer

• Curse the Weak should probably have a save, and the save should probably be repeated at the end of each turn.
• Staggering Strike incapacitating on a crit is pretty strong. This and the above ability is likely to completely trivialize solo fights as written. One alternative may be to borrow the effect from Tasha's Mind Whip and restrict them to the choice of only one action, move, or bonus action on their next turn.

Oath of the Pursuer

• Detect Thoughts seems a little redundant with the Channel Divinity that does the same thing.
• Read Thoughts - You should clarify if there is any indication by anyone watching that you are doing this, because it's bound to come up in play. Subtle Spell + Detect Thoughts is quite a bit better than regular Detect Thoughts alone, and it feels a little off-brand to me for a paladin sworn against lies to do something as sneaky as mind-reading without fair warning.
• Smite the Feebleminded - a high INT paladin is interesting, but seems pretty hard to achieve as they already are spread thin between STR/CON/CHA. I'm not sure how to fix this though.
• Mind Leech - Monsters can have this because PCs rarely have INT below 6-8 (and when they do they deserve to die). But there are CR 15+ monsters that this ability can pretty reliably one-shot. The Tarrasque has an INT of 3 for example. Maybe it could temporarily stun, or you could borrow some ideas from feeblemind.
• Omniscient - I'd separate the initiative bonus and the reaction just for clarity. It reads a bit like you have to take the reaction to get the init bonus. Also, expertise in saves isn't really a thing anywhere else (because it's ridiculously good) and may be too strong even for a capstone.

Thank you so much!  I appreciate the feedback!  I will try to make this more balanced and comprehensive.  I will post the next version when I am done.

Once again, thank you so much!

Also, I'm an eejit, I forgot to reread the curse the weak feature and I would've added a save 

Paladins - The Homebrewery (naturalcrit.com)

There is the revised version

Please give more feedback :)

I appreciate it!
