Go back to 5e - Paladin.
🦸♀️5e - Spellknight🦸♀️
Spellknights believe in maintaining the balance of power between the ordinary and the extraordinary, including themselves. These paladins are resourceful and quick to remember their own mortality and privilege, often choosing to pursue mundane solutions before magical ones. Despite their caution, these wardens of balance are exemplary arcanists who can feel the weave of magic in the world as keenly as some of the finest sorcerers.
Level 3: Spellblade Knowledge (Flavor)
You gain 💃Arcana, and 💃Nature 🎲Proficiency, or one level of 🎲Expertise, if you are already proficient.
Level 3: Channel Oath
You can channel divine energy to fuel magical effects. Other Paladin features might give additional Channel Oath effect options. Each time you use Channel Oath, you choose which effect from this class to create.
If a Channel Oath effect requires a 🎲Save, the 🎲DC equals the ☄️Spell Save DC from this class’s Spellcasting feature.
Absorb Magic: You can refute certain spells and use them to nourish yourself. When you see a creature within 30 feet of you casting a spell, you can take a Reaction and expend a use of your Channel Oath to interrupt it. You make an 🎲Ability Check (d20 + your CHA + 1/3 x your Paladin level), contested by the creature’s 🎲Ability Check (d20 + its Spellcasting Ability + the spell's level). Success: The spell dissipates with no effect, and the Action, Bonus Action, or Reaction used to cast it is wasted. If that spell was cast with a spell slot, the slot isn’t expended. You also gain 💖Temporary Hit Points equal to your CHA + 5 x the dissipated spell's level.
Number of Uses: You can use this feature a number of times as stated in the Paladin Class Table. You regain 1 expended use when you finish a Short Rest, and you regain all expended uses when you finish a Long Rest.
Level 3: Spells of the Spellknight
The magic of your oath ensures you always have certain spells ready; when you reach a Paladin level specified in the table below, you thereafter always have the listed spells prepared.
3rd level Paladin: ☄️Bane, ☄️Detect Magic
5th level Paladin: ☄️Hold Person, ☄️Magic Aura
9th level Paladin: ☄️Dispel Magic, ☄️Slow
13th level Paladin: ☄️Dimension Door, ☄️Resilient Sphere

Level 7: Aura of Warding
Ancient magic lies so heavily upon you that it forms an eldritch ward; you and your allies have Resistance to damage from spells while in your Sacred Aura.
Level 11: Spellslinger
When you take the ⚔️Attack action on your turn, you can replace one of the 🎲Attacks with a casting of one of your cantrips that has a casting time of an Action.
Level 15: Armored Focus
While you are 🎲Concentrating on a spell, your 🎲Concentration can’t be broken as a result of taking damage.
Level 19: Arcane Conduit
As a Bonus Action, you can imbue your Sacred Aura with crackling magic, granting the benefits below for 10 minutes or until you end them (no Action required).
Diminish Defiance: Enemies in the aura have DISADV on 🎲Saves against your spells and Channel Oath options.
Magic Resistance: While in your Sacred Aura, you and your allies have ADV on 🎲Saves against spells and magical effects.
Swift Spells: Whenever you cast a spell that has a casting time of an Action, you can cast it using a Bonus Action instead.
Number of Uses: Once you’ve used this benefit, you can’t use it again until you finish a Long Rest. You can also restore your use of it by expending a level 5 spell slot (no Action required).
