World of Al'Dravin
Hatred brings forth willpower, willpower brings forth the resolve to act unshaken and fearlessly, to take matters to your own hands. To the Rage Mage, this hatred is so deep the will it grants is enough to shatter reality under their fists. Some are barbarians who dedicated their lives to further control their rage, exiling themselves to learn mysteries and secrets of magic, other are leftovers of ancient blood mingling akin to sorcerers from simpler or tribal communities, awakening fiendish or draconic destruction as they roar and foam, but regardless of their origins, all Rage Mages are known to trespass the borders of magic as a fine and precise art by fueling it with wrath, casting during deliriums most men would have trouble to barely think through.
Spell Rage. Beginning at 3rd level, you can cast spells while in a rage. Your rage damage applies to damage spells cast while in a rage. If a spell cast damages more than one target, you may only apply extra rage damage to one of the targets. In addition, casting spells during rage counts as attacking for the purposes of ending rage. You are unable to concentrate on spells while raging. When you choose this path select a spell school other than Evocation. It will apply later.
Spell Slots. The Eldritch Knight Spellcasting table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these spells, you must be in a rage and expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.
Spells Known of 1st-Level and Higher. You know three 1st-level Sorcerer spells of your choice, two of which you must choose from the Evocation or (the other school) spells on the Sorcerer spell list. The Spells Known column of the Eldritch Knight Spellcasting table shows when you learn more Sorcerer spells of 1st level or higher. Each of these spells must be an evocation or (the other school) spell of your choice, and must be of a level for which you have spell slots.
Spellcasting Ability. Charisma is your spellcasting ability for your Sorcerer spells. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a Sorcerer spell you cast and when making an attack roll with one.
Arcane Fury. Beginning at 6th level, weapons and magic are equally an extension of your rage. You can use an action to make a melee attack with Reckless Swings. Instead of gaining advantage on your attack you can cast a spell as a bonus action. This spell must use a spell slot no higher than 1/3 of your character level.
Wrathful Resistance. As your rage boils in your blood, it disrupts the flow of magical energy around you. At 10th level, while raging, you have advantage on all saving throws against spells.
Eldritch Storm. You can expel the might of your rage all at once to unleash a devastating storm of eldritch magic. Beginning at 14th level, when you can end your rage early as an action, all creatures within 15 feet of you must make a Dexterity saving throw. On a failed save, a creature takes 1d6 force damage for each round of rage you have left, or half as much on a successful one. After you use this ability, you cannot use it again until you complete a short or long rest.
