イナンナの冥界への降臨では、イナンナは恋人ドゥムジに対して非常に気まぐれな態度で接している<ref>Black, Green, 1992, pp108–9</ref>。イナンナのこのような性格は、後のアッカド語標準訳『ギルガメシュ叙事詩』の中で、ギルガメシュがイシュタルの恋人たちへのひどい仕打ちを指摘する際に強調されている<ref name="Gilgamesh' p. 86">''Gilgamesh'', p. 86</ref><ref>Pryke, 2017, page146</ref>。
In ''Inanna's Descent to the Underworld'', Inanna treats her lover Dumuzid in a very capricious manner. This aspect of Inanna's personality is emphasized in the later standard Akkadian version of the ''[[Epic of Gilgamesh]]'' in which [[Gilgamesh]] points out Ishtar's infamous ill-treatment of her lovers.<ref name="Gilgamesh' p. 86">[[#Reference-Gilgamesh|''Gilgamesh'']], p. 86</ref>{{sfn|Pryke|2017|page=146}} However, according to assyriologist Dina Katz, the portrayal of Inanna's relationship with Dumuzi in the Descent myth is unusual.{{sfn|Katz|1996|p=93-103}}{{sfn|Katz|2015|p=67-68}}
Inanna was also worshipped as one of the Sumerian war deities.{{sfn|Black|Green|1992|pages=108–109}}{{sfn|Vanstiphout|1984|pages=226–227}} One of the hymns dedicated to her declares: "She stirs confusion and chaos against those who are disobedient to her, speeding carnage and inciting the devastating flood, clothed in terrifying radiance.
