Range Strategy
Must be in Soul Form. Clear the the first 2-3 dreglings and stand behind either the last or the second last pillar from her. Use zoom to aim and fire one arrow, then immediately hide back behind the pillar, as she will cast Soul Ray. It's a little far, so aim slightly above and to the left of her shoulder. Repeat until she dies. The clone won't even appear.

Tested this strategy in Body Form on NG+ with the White Bow from the second-to-last pillar. Idol did not disappear or make clones.
