Intresting "Coordinated Positioning" skill interaction with this boss. Just happened my Eder was tank with fighter/rogue multiclass. So this boss dont moving by herself she can be moved by using this skill to an exit/ From that distance she cant open her sigils. But to end fight u have to kill sigils as well, so u can move her to open 1 sigil only and kill it with focusing specific sigil. From this distance she can use spells on ur entire party.
