Urill, Alythana's One True Knight

Warforged Resilience. The warforged has advantage on saving throws against being poisoned and is immune to disease. Magic can’t put it to sleep.

Spellcasting. The warlock is a 10th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). It regains its expended spell slots when it finishes a short or long rest. It knows the following warlock spells:

Cantrips (at will): eldritch blast,  mage hand, minor illusion, prestidigitation

1st–5th level (3 5th-level slots): blink, dimension door, dominate beast, faerie fire, fear, hold monster, mirror image, misty step, phantasmal force, seeming, sleep

Eldritch Invocations. The warforged warlock has the following features:
1. When it casts eldritch blast, it adds +2 to Damage Rolls, 300 ft. range, & can push hit targets up to 10 feet away in a straight line.
2. Once on each of its turns when hitting a creature with eldritch blast, you can reduce that creature's speed by 10 feet until the end of your next turn.

War Caster. The warforged have advantage on CON saving throws that you make to maintain your concentration on a spell when you take damage. You can perform the somatic components of spells even when you have weapons or a shield in one or both hands. You can use your reaction to make an opportunity attack to cast a spell that has a casting time of 1 action and targets only that creature.

Multiattack. The warforged attacks twice with one of its weapons.

Greatsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 3) slashing damage.

Javelin. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Protection. When an attacker the warforged can see makes an attack roll against a creature within 5 feet of the warforged, the warforged can impose disadvantage on the attack roll.
