Fist of Arcanum

Wizards who follow the Fist of Arcanum often travel far distances to learn the balance of Creation and Destruction. Finding themselves under the tutelage of monks or druids. Balance is the key to life, practitioners of this school of magic learn how to deal frightful damage while holding onto a secret weapon just in case.

Mark of Destruction

2nd-level Fist of Arcanum feature

You gain the ability to perform a monastic ritual to bind magical energy to your body. The ritual takes 10 minutes to perform, during which you can expend a number of spell slots to create a Mark of Destruction on your body equal to the total number of spell slot levels you expend. These marks count as a spellcasting focus for your wizard spells as long as they are active. You can have a number of these marks equal to your proficiency bonus and the marks reset after a long rest.

In addition, you gain a number of Destruction Dice equal to your proficiency bonus, the dice is a d4. You can use your Marks of Destruction to cast Evocation spells as if they were spell slots, expending a number of them equal to the spell's level to cast it. When you do so you can roll the maximum number of destruction dice you have and add it to one damage roll of the spell's damage type against one creature. 

Mark of Creation

2nd-level Fist of Arcanum feature

During your monastic ritual, you can also expend a number of spell slots to create a Mark of Creation on your body equal to the total number of spell slot levels you expend. These marks count as a spellcasting focus for your wizard spells as long as they are active. You can have a number of these marks equal to your proficiency bonus and the marks reset after a long rest.

While a Mark of Creation is on your body you gain temporary hitpoints at the start of each of your turns equal to your proficiency bonus. In addition, your AC increases by half your proficiency bonus rounded up as long as you have a Mark of Creation on your body.

You can use your Marks of Creation to cast Conjuration Spells as if they were spell slots, expending a number of them equal to the spell's level to cast it. When you do so you can cast that spell as a bonus action.

Equivalent Transfer
