Swordmage

Swordmages are powerful spellcasters who blended martial combat with magic. These rangers trained alongside wizards to develop their skills. Wielding swords enchanted with spells, swordmages were powerful foes to cross, hardened through years of training in the melding of spell and blade.

Rangers who choose this conclave usually have a more scholarly approach to magic. If you so choose, you can opt to make Intelligence your spellcasting ability instead of Wisdom, and replace the subclass abilities requiring your Wisdom modifier to require your Intelligence modifier instead.

Blade and Magic

At 3rd level, you learn two cantrips of your choice from the wizard spell list. You learn an additional wizard cantrip of your choice at 10th level. In addition, when your Spellcasting feature lets you learn a ranger spell of 1st level or higher, you can choose the new spell from the evocation or abjuration schools from the wizard spell list or from the whole ranger spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a ranger spell for you. The spells you learn at 8th, 14th, and 20th level can come from any school of magic.

Aegis

You learn the hunter's mark spell, and it doesn't count against the maximum number of ranger spells you can learn. When you cast the spell, the target doesn't need to fall to 0 hit points for you to change target. Whilst under the effects of your hunter's mark, a creature suffers a -2 penalty to all its attack rolls against creatures other than you.

In addition, you can cast the hunter's mark spell at its lowest level without expending a spell slot once per long rest. If you do so, damage can't break your concentration on this spell.

Pick one of the following aegis. You cannot change it later. You must also have a free hand to use an aegis.

Aegis of Assault

If the marked target is within 30 feet of you and deals damage to a creature other than you, you can use your reaction to teleport to an unoccupied space adjacent to it and make one melee weapon attack against it. This fails if there are no unoccupied spaces available.

Aegis of Ensnarement

If the marked target is within 30 feet of you and deals damage to a creature other than you, you can use your reaction to teleport the marked target to a solid surface in an unoccupied space, and you have advantage on your next attack roll against it. This fails if there are no solid surfaces or unoccupied spaces available.

Aegis of Shielding

If the marked target is within 30 feet of you and deals damage to a creature other than you, you can use your reaction to diminish that damage by an amount equal to your ranger level + your Wisdom modifier.

Teleporting Enforcer

Starting from 7th level you can, as a bonus action, teleport a number of feet equal to 10 x your Wisdom modifier. You can use this ability only if you haven't moved that turn, and after using it, your speed is 0 until the end of your current turn. Beginning at 15th level, you can ignore that restriction.

Magi-Breaker

You are the bane of magic users. At 11th level, your body is attuned to magic, empowering you. When you cast an abjuration spell that requires you to make an ability check as part of casting that spell (as in counterspell or dispel magic), you add a bonus equal to your Constitution modifier (minimum of +1) to that check.

Relentless Aegis

At 15th level, every time an enemy under the effect of your hunter's mark spell deals damage to a creature other than you, it takes force damage equal to your Wisdom modifier if you are not incapacitated.
