Electromancer

You are skilled at using lightning to shock others, granting you the following benefits:

• You spellcasting ability score increases by (if you use multiple ability scores for spellcasting, choose one of them to increase).
• Once per turn, when you deal lightning damage to a creature with a spell of 1st level or higher, you cause that creature to be unable to take reactions until the start of its next turn.
• When you score a critical hit with a spell that deals lightning damage to a creature, you can cause the spell's energy to leap from the target to a different creature of your choice within 30 feet of it. Make a new attack roll against the new target, and make a new damage roll on hit, which could cause the spell's energy to leap again on another critical hit. A creature can only be targeted once by each casting of a spell.
