Radiant Pikeman

Beginning when you choose this archetype at 3rd level, when a creature you can see enters your reach, you can use your reaction to Shove the creature. To use this feature, you must be wielding a glaive, halberd, lance, pike, or spear.

Starting at 3rd level, when you deal damage with a glaive, halberd, lance, pike, or spear, you can choose for the damage to be radiant instead of its normal damage type.

At 7th level, you bolster your allies when fighting shoulder to shoulder. While you have an ally within 5 feet of you who isn't incapacitated, you can use a bonus action to take the Help action to assist that ally's attack roll or their next Strength (Athletics) or Dexterity (Acrobatics) check.

Beginning at 10th level, your faith and training make you a daunting foe of dark creatures. Once per turn, you can have advantage on an attack roll or ability check made against a fiend, undead, or creature of shadow.

Starting at 15th level, once per turn when you are hit by a melee attack, you can choose to move 5 feet away from the attacker without provoking opportunity attacks. If you do, the attacker takes 1d6 radiant damage. To use this feature, you must be wielding a glaive, halberd, lance, pike, or spear.

At 18th level, you have advantage on saving throws against spells. If you fail a saving throw against being charmed or frightened, you can choose to succeed instead. You can use this feature a number of times equal to half your proficiency bonus. You regain all expended uses when you finish a long rest.
