Arcane Infusion

There is a well of arcane power within you, represented by a number of dice equal to one plus your Intelligence modifier (minimum 1), that replenishes at the end of a short or long rest. Using this pool of Infusion dice, you may charge your weapon with destructive elemental energies. Choose an element: fire, lightning, cold or acid; your Infusions, when they deal damage, deal this damage type. You may change the damage type of your Infusion at the end of a long rest.

As a bonus action, touch a weapon you are wielding, giving it a crackling energy and a slight glow. Select a number of d4s up to the number remaining in your pool. When you have an active Infusion, you may expend one Infusion die to add its roll to the damage of your melee attack. This damage is of the Infusion’s type.

The ward is spent when there are no more dice available, when you stop wielding the weapon, or when you finish a short or long rest. Creating a second Infusion causes the first to vanish and any remaining dice are lost. You may end the Infusion as a free action.

At 14th level, your Infusion dice become d6s.

Spellblade Training

At 2nd level, your training in the arma arcana gives your combat a flair that others lack. Choose one of the following options:

• Agile Assault. You can use Dexterity instead of Strength for the attack and damage rolls of weapons with the versatile or heavy traits. You must use the same modifier for both rolls.

• Arcane Aegis. While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Intelligence modifier. You can use a shield and still gain this benefit.

Evocant Sigil

Upon reaching 2nd level, you learn to seal vicious magical energies into other creatures in the form of sigils. Choose a damage type: fire, cold, lightning or acid. You may change the damage type of your sigils at the end of a long rest. The damage type of your Sigil need not be the same as that of your Arcane Infusion feature.

As a bonus action, you may expend spell slots to place a sigil on one or more creatures within 30 feet. The number of sigils you may place with this action is given on the Sigil table above: 2 for a 1st level slot, 3 for a 2nd, etc. Only one sigil can affect a creature at one time, and you can only utilize your own sigil-marks for the purposes of spellcasting.

Maintaining your sigils does not require your concentration, but you must make a concentration check when you take damage with sigils active. Each time you fail this special concentration check, choose one sigil-marked creature; that sigil dissipates without effect, but you maintain all your other sigils. If you are concentrating on a spell, use the result of that check to determine whether you lose a sigil in addition to the spell.

Only the Spellblade who placed the sigil, or a detect magic spell, can view the sigil, unless the Spellblade chooses to make it visible; it appears on the target’s skin as a faintly-glowing glyph of the Spellblade’s design.

When an attacker hits a creature bearing a sigil that it can see, it may choose to strike and burst the sigil. The sigil’s energies are released in a flare of elemental magic, inflicting 2d4 damage of the sigil’s damage type as part of the melee attack.

Sigils dissipate if not burst in one minute, or on the death of the sigil-marked creature.

Sigils per Spell Slot Level

Spellcasting

By 2nd level, you have learned to manipulate the intricacies of arcane magic to cast spells.

Spellcasting Focus

You may use a bladed weapon that you are proficient in, or an arcane focus, as the spellcasting focus for your Spellblade spells.

Learning Spells of 1st Level and Higher

Each time you gain a Spellblade level, you can add one Spellblade spell of your choice to your spellbook for free. Each of these spells must be of a level for which you have spell slots, as shown on the Spellblade table. On your adventures, you might find other spells that you can add to your spellbook (see “Your Spellbook”).

Spellblade Specialist

Upon reaching 3rd level you choose your specialty, beginning to design your own personal relationship with the arma arcana. You choose either Shadowdancer, Warblade or Arcanamach as your path.

You gain your Specialty’s Occult Optima at 3rd level, and additional Specialist abilities at 7th and 15th level.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Abjurant Infusion

At 6th level, your Infusion can be used to supplement your defense as well as your offense. While the Infusion is active, you may use your reaction to roll one or more of these dice to reduce damage dealt to you by the number rolled; the damage reduction is doubled if the damage and ward are of the same type. If the reduction is greater than the damage, you gain temporary hit points equal to the overage.

Also, when you deal damage with an Infused attack, all of your weapon damage is considered magical for the purposes of overcoming resistance and immunity to nonmagical attacks and damage.

Transmutant Burst

At 9th level, you synergize your Infusion and Sigil to cause additional effects. When you use an Infusion die against a sigil-marked enemy, you may choose to either maximize that die, or cause the following effect corresponding to your Sigil type in addition to the die damage:

• Acid. Acid corrodes the sigil-marked's armor. Their AC is reduced by 2 as armor is damaged or natural armor is weakened. A creature cannot be affected by this effect more than once. Restoring this AC requires repair (for armor) or healing equal to the damage dealt by the attack.
• Fire. Flames burn the sigil-marked. The target must make a Constitution saving throw on the beginning of each of its turns, or take 1d6 fire damage. A successful saving throw, or an action spent extinguishing the flames, ends this effect.
• Lightning. Shock distracts the sigil-marked. Their attack rolls have disadvantage until the end of their next turn.
• Cold. A shower of razor-sharp ice blasts from the sigil. Any creatures in a 15' cone emanating from you towards the target must make a Dexterity saving throw or take 1d6 cold damage.

Conjurant Circle

At 10th level, your connection with the elemental planes has strengthened to the point that you can summon minor denizens of those planes. As an action, you may summon up to two mephits to serve you for up to one minute, appearing in an unoccupied space you can see wtihin 30'. The mephits obey your commands to the best of their ability. A summoned mephit cannot summon additional mephits. They act on the same initiative you act on. If you die or fall unconscious, the mephit returns to its home plane. Once you have used this ability, you are unable to use it again until you have finished a long rest.

If your Infusion and Sigil are of the same type, you summon two mephits of the corresponding type. If they are of differing types, you summon one of each.

Necromant Sigil

Upon reaching 11th level, you have learned to tie your sigils to your own life, draining some of the energy from them to yourself.

Bursting a sigil deals an additional 1d4 damage and you regain 3 hit points.

In addition, you may spend two Infusion dice when you hit an enemy. You may maximize both dice at once when using Transmutant Burst, or use the option corresponding to the element of your Sigil.

Divinant Blade

At 18th level, you are a master of the arma arcana and always prepared for combat. When you roll for initiative with less than half your maximum Infusion dice, you regain two dice.

Martial Maelstrom

Starting at 20th level, as an action you can emanate elemental energies.

For one minute, a maelstrom of elemental wrath affects the area around you to a distance of 30 feet, with the clash of forces generating cacophonous noise and heavily obscuring the area and an additional 30 foot radius. Your vision and hearing are unaffected.

Whenever an enemy creature starts its turn in the maelstrom, the creature takes 2 damage from each of the following types: fire, cold, lightning, acid, thunder (10 damage total).

You regain the use of this ability at the end of a long rest.

Warblade

Spellblades who prefer power over finesse often choose the path of the Warblade, using heavy plate to ward off blows while smashing their foes with might and magic. Many Warblades are lawful neutral and proudly avoid being “tainted” by distractions such as good or evil, but some who rise in power shift toward tyrannical and cruel natures.

Ars Rejuvis

Your enemies’ life force restores your allies’ health. Until the end of your next turn, when an ally makes a successful melee weapon attack against a sigil-marked enemy within range, they regain hit points equal to your Intelligence modifier (minimum 1). This does not burst the sigil.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, the spell heals 1d6 additional damage for each slot above 2nd.

Ars Ultimatum

Shadow Conjuration

• 4th-level conjuration
• Casting Time: 1 action
• Range: see text
• Components: V, S, M
• Duration: Concentration, Up to 5 minutes

You summon a deadly shadow to serve you in combat. This shadow has the statistics of a shadow demon (MM pg.64), but is bound to serve you. It appears in an empty space you can see, and it disappears when it drops to 0 hit points or you lose concentration.

Roll initiative for it. When you summon it and on each of your turns, you can issue a verbal command for its next turn without using any action. If you issue no command, it attacks any creature in reach that has attacked it.

The shadow loses 3 hit points if it ends its turn in an area of dim light, or 10 in an area of bright light.
