Inquisitor - Revamped

An inquisitor is a member of the Magi Enforcers who exist to protect the world from chaotic and evil magic. Due to spellcasters running rampant through the planes, causing chaos wherever they go, the Inquisitors are tasked to seek and regulate them and their magic. There are exceptions to this rule: spellcasters who are registered and agree to the Magi code are allowed to continue the study and practice of magic of their own free will.

Inquisitor's Knowledge

Inquisitors gain proficiency in the arcana skill due to their studies of magic and how to foil it.
They are so aware of magic around them that they are able to cast detect magic a number a times equal to their proficiency bonus per long rest without requiring concentration.

Arcane Foundation

When you choose this fighter archetype at 3rd level, you learn Arcane Charges that are fueled by charge dice.

Arcane Charges. You learn two charges of your choice, which are detailed under “Arcane Charges” below. Many charges enhance an attack or defense tactic in some way. You can use only one charge per turn. Your reaction is not considered to be a part of your turn.

You learn two additional charges of your choice at 7th, 10th, and 15th level. Each time you learn a new charge, you can also replace one charge you know with a different one.

Charge Dice. You have four charge dice, which are d8s. A charge die is expended when you use it. You regain all expended charge dice when you finish a long rest.

You gain another charge die at 7th level and one more at 15th level.

Charge save DC = 8 + your proficiency bonus + your intelligence modifier
