Xelora, Hand of Talos

Magic Resistance. Xelora has advantage on saving throws against spells and other magical effects.

Storm Sorcery (Wild Magic).
When Xelora casts a spell of 1st level or higher, she must roll a d20. On a roll of 1, a wild magic surge occurs, causing a random effect from the Wild Magic Surge table (PHB pg. 104). Additionally, whenever Xelora casts a spell that deals lightning or thunder damage, she can add half her Charisma modifier (rounded up) to one damage roll of that spell.

Spellcasting. Xelora is a 14th-level spellcaster. Her spellcasting ability is Charisma (spell save DC 17, +9 to hit with spell attacks). Xelora can cast levitate at will and has the following sorcerer spells prepared:
