Arcane Discovery: Dread Focus

Through iron will, forgotten mediation techniques, or extensive mental exercises from a unique teacher, you have researched and implemented a method to maintain TWO active concentration effects. Any damage or effect that would challenge concentration must be tested against both effects separately. Further, a concentration check is required to use a reaction or bonus action spell effect while holding the second concentration effect. Any and all feats that apply to concentration checks apply to these rolls. 50,000 gold is required to reflect the significant resources required to find and implement this result.
