She can't drop Gheeds and she can't drop anything from TC>TC45. (TC45 itself is quite rare from her) - that leaves most nice exceptional uniques out (all class specific for example). She is good for dropping Skin of Vipermagi, Kelpie Snare, Rockstopper, Ribcracker. Hone Sundan and Shaftstop are TC45 and they are very rare from her (rarer than SoJ).
From unique jewelry she can drop only Manald, Nagel, SoJ, Mahim-Oak, Nokozan relic, Eye of Etlich, nothing more.
