It does enough damage to overcome her Regen and kill her in about 4* minutes (150' range). If you happen to have Elven Accuracy (e.g. you're a Bladesinger or an Evoker-type interested in Scorching Ray + Spirit Shroud), you can do 45 DPR which translates to 15 damage a turn counting her regeneration. 585 [615-30 - she drops to 0 before regen]/15 = 39 rounds so about 4 minutes, give or take. If you have an 18+ Dex (e.g. from Magic Jar: this adventure features plenty of good targets, e.g. the Dragonsoul Cultists which give you +3d6 on an attack with advantage and 18 Dex) body, you don't need Elven Accuracy - 18 Dex and +1 weapon would do 40ish DPR which amounts to 6 minutes to kill her . . .
