An Arcane Archer studies a unique elven method of archery that weaves magic into attacks to produce supernatural effects. Arcane Archers are some of their most elite warriors among the elves. They stand watch over the fringes of elven domains, keeping a keen eye out for trespassers and using magic-infused arrows to defeat monsters and invaders before they can reach elven settlements. Over the centuries, the methods of these elf archers have been learned by members of other races who can also balance arcane aptitude with archery.

This arcane archer has a lot more Arcane shot options, which have their power increased at 10th and 15th level, as well as having more diverse and powerful arcane shots, which are level locked. I took inspiration from the Warlocks invocations. The arcane archer also has a lot more points he can use, but they only recharge on a long rest. The lvel 18 ability makes his versatility rise to a new level at the expense of more magic points (wich are the cost for higher level arcane shots) but may have to be reined in by the DM, as the wording is not 100% foolproof, as such any combined shot must be approved by the dm before being used.

Arcane Archer Lore

At 3rd level, you learn magical theory or some of the secrets of nature — typical for practitioners of this elven martial tradition. You choose to gain proficiency in either the Arcana or the Nature skill, and you choose to learn either the prestidigitation or the druidcraft cantrip.

Arcane Shot

At 3rd level, you learn to unleash special magical effects with some of your shots. When you gain this feature, you learn an amount of Arcane Shot options equal to 1+ your proficiency modifier. You can choose to relearn arcane shots after every long rest, where you must reinchant your arrows. If an arcane shot option has a requirement, you must meet it first to learn it.

You gain a pool of Arcane energy that you can tap into to imbue your arrows with magical energy. This pool has an amount of Arcane power points equal to 3 times your peoficiency modifier, and replenishes on a long rest.

When you fire an arrow from a shortbow or longbow as part of the Attack action, you can apply one of your Arcane Shot options to that arrow. You decide to use the option when the arrow hits a creature, unless the option doesn’t involve an attack roll.

Arcane Arrow

At 7th level, you gain the ability to create arrows of Arcane matter. When you draw the string of your bow with no arrow knocked, an arcane arrow made up of magical force manifests, wich counts as magical damage for overcoming resistances.

Curving Shot

At 7th level, you learn how to direct an errant arrow toward a new target. Once per turn when you make an attack roll with a magic arrow and miss, as a reaction you can reroll the attack roll against a different target within 60 feet of the original target.

Arcane Recharge

At 15th level you gain the ability to reattune to your arcana power, and as a bonus action recharge a number of magic points equal to twice your intelligence modifier.

Heightened Arcane Shot

Starting at 18th level, your magical prowess increases immensely, and you can add two of your arcane shot options to one arrow, expending points for both. When choosing two options for one arrow, their effects combine, but you must choose the additional damage the shot deals from one of the two options. So combining an elemental shot with a mass duplicating arrow will for example change the damage type of the volley to fire, but not do additional damage.

Arcane Shot Options

The Arcane Shot feature lets you choose options for it at certain levels. Some Arcane arrow options have limitations and can only be taken when the requirements are met.

If an option requires a saving throw, your Arcane Shot save DC equals 8 + your proficiency bonus + your Intelligence modifier.

Arrow of Disintegration

15th level. You imbue the arrow with your most powerful destruction magic. After an arrow hits a creature, it must make a constitution saving throw, or take the arrows damage aswell as an additional 40 force damage.

If the target of this arrow is not a creature but an object or creation of magical force, the arrow automatically disintegrates a Large or smaller nonmagical object or a creation of magical force. If the target is a Huge or larger object or creation of force, it disintegrates a 10-foot- cube portion of it. Magic items are unnafected.
