Plays well with community›
- Nezglekt — Althea's Fractured Minds makes enemy Insanity shred their Mind resistance, so Nezglekt flooding Insane/Sight directly amplifies her mental attacks (and he passively heals off it). [14][15]
- Gustav — Gustav can convert his damage to Mind and make Mind scale with Sharp; his Sharp/Insanity support stacks onto Althea's Resonance-fueled Mind (Echo) damage build. [14][15]
