Prismatician

A Prismatician is an artificer who researches and specializes in the unique material, the Aldian Prisms. They use these prisms to modify and forge unique weapons which push arcane energy through these special prisms, projecting a dangerous arcane force. Prismatic weapons are often built for the crafter's use, so many prismatic artificers are effectively trained in martial combat. 

Prismatic Combatant

You gain proficiency with martial weapons and heavy armor.

Prismatician Spells

3rd-level Prismatician feature

You always have certain spells prepared after you reach particular levels in this class, as shown in the Prismatician Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Prismatician Spells

Prismatic Weaponry

3rd-level Prismatician feature

You modify a weapon utilizing the arcane prisms to bolster it. You apply prisms to a melee weapon to change it into a prismatic weapon over the course of 1 hour working on it. This crafting can be done during the attunement process. The weapon retains all properties it has except for the damage die which converts to a d8. Only Prismatician artificers are proficient with prismatic weapons. If the weapon was already magical it retains the magical effects. The damage type of your prismatic weaponry is dependent on the roll of the d8 as seen in the chart below.

Number Rolled	Damage type
1	Acid
2	Cold
3	Fire
4	Force
5	Lightning
6	Poison
7	Psychic
8	Thunder

Fighting Style

At 3rd level, you adopt a style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if something in the game lets you choose again.

Blind Fighting

You have blindsight with a range of 10 feet. Within that range, you can effectively see anything that isn’t behind total cover, even if you’re blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.

Defense

While you are wearing armor, you gain a +1 bonus to AC.

Dueling

When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Interception

When a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage). You must be wielding a shield or a simple or martial weapon to use this reaction

Protection

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Thrown Weapon Fighting

You can draw a weapon that has the thrown property as part of the attack you make with the weapon.

In addition, when you hit with a ranged attack using a thrown weapon, you gain a +2 bonus to the damage roll.

Two-Weapon Fighting

When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Extra Attack

5th-level Prismatician feature

You can attack twice, rather than once, whenever you take the Attack action on your turn.

Channeled Energy

5th-level Prismatician feature

You flow more arcane energy into your weapon for a brief moment to increase your weapons potency. Once per turn, when you hit a target with a prismatic weapon you can roll an additional d8 for the damage. You then select from the 2d8s which damage type you would like the strike to deal. If 2d8s are the same add your proficiency modifier to the damage of the attack.

This ability further increases to 3d8s at 15th level. You then select the damage type from the 3d8s.

Prismatic Protection

9th-level Prismatician feature

Whenever you hit a creature with your prismatic weaponry on your turn, you gain resistance to the damage type(s) you deal with your prismatic weapon until the start of your next turn. Additionally, if you are concentrating on a spell or ability and take damage from the resisted type granted by this ability, you automatically succeed on the concentration check.

Refract Energy

Starting at 9th level, whenever you are hit with an attack while under the effects of your Prismatic Protection ability, you can use your reaction and release the prismatic resistance. Upon doing so, all creatures within 5 feet of you must make an intelligence saving throw. On a failure a creature takes 1d10 + your intelligence modifier of the damage type you resisted, as granted by your Prismatic Protection ability. On a success a creature takes no damage. After using this ability you lose the resistance to the damage type. 

Arcane Aftereffect

15th-level Prismatician feature

Your prismatic weapon ebbs and flows with your arcane output. Whenever you use your action to cast an artificer spell of first level or higher, you can make an attack with your prismatic weapon as a bonus action.
