When seeking to create a customized spell, collaborate with the DM to determine the appropriate properties of the spell, and ultimately what the spell level should be for the desired effect. Then there are two ways to obtain your custom spell. The first way is to replace one of your newly learned spells as part of a level up with the custom spell you created. The second, is to research the spell. Any class can research a spell. A Wizard might spend night trying new sigil sequences and words of power, while a Sorcerer might practice the spell over and over again, refining their ability to control their innate power into the shape they want.
To research a spell, consult the spell research chart below. Research is done in research cycles. At the beginning of the research cycle, you must spend the Component Cost (in gold pieces) for that cycle. The component cost of the initial research cycle is listed on the table, which represents the materials, equipment, and books used to research the spell. The research time is the amount of time that will need to be invested to complete the research cycle.
Once the research time is completed, an Intelligence (Arcana) check is made against the research DC. On a success, the spell is successfully researched that cycle, and is learned by the researcher. If you are proficient in Calligrapher's Supplies, you may also create a spellscroll of the researched spell at no additional cost. If the research DC is failed on the initial research cycle, the spell is not successfully researched, but the endeavor is not over. You may continue into another research cycle for the spell. All research cycles beyond the initial one have their component cost, and research time reduced by half, and the research DC is cumulatively reduced by 2 for each previously completed research cycle.
