While the Paladin has a broad access to a unique selection of unique spells by way of their smites, this spell list expands on the abilities available to them. The cleric and paladin share a lot of crossover in abilities of faith, so there are similarities, but disparity is maintained as best as possible. Many of the new paladin spells that debuff and buff enemies and allies respectively, rather than inflicting large amounts of damage or conjuring celestial beings.
The standard paladin has damage output well and truly covered, so a selection of additional spells that provide a divinely flavoured number of buffs and debuffs compliments the paladin well. Of the spell series so far, I believe this list contributes a lot to widening the selection without risking overbalancing a class. Enjoy!
