Legendary Feat
After years of pushing yourself to new heights, your understanding of the arcane has surpassed that of the average magic user. You have learned to split your focus, allowing the concentration of one spell to fade into your subconscious while weaving another. This has numerous effects:
Dual Concentration. You can focus on two concentration spells at once with implications:
- When casting the second spell, roll a d20. If you roll higher than the spell's level, you are successful. On a fail, the first spell ends abruptly and triggers Arcane Fatigue.
- While concentrating on two spells, movement is cut by half, and the saving throw to maintain concentration is done at disadvantage.
- If concentration is broken by a failed save, trigger Arcane Fatigue.
- You cannot cast more than one instance of a spell at a time.
- Dropping concentration willingly must be done one spell at a time (One spell per turn), or roll for arcane fatigue.
Arcane Fatigue : The result of straining to concentrate on two spells at once leaves you vulnerable. When arcane fatigue triggers, the caster is stunned for one turn. Once arcane fatigue wears off, the caster cannot cast leveled spells for 1d4 turns.
Counterspell: Using counterspell on the 2nd concentration spell will stop the casting of that spell without triggering arcane fatigue, meaning the first spell remains active. Counterspell triggers after the d20 roll.
Requisites: 8 levels in the same magic-focused class. (Wizard, Warlock, Druid, Sorcerer, Priest, Bard)
Important note: Twinning spells with metamagic will not be possible in conjunction with this feat.
For flavor, the term 'arcane fatigue' can be altered to match the magical nature of the user. (I.E. Fiendish fatigue, eldritch fatigue, etc.)
