Terminus beats Moji in melee range. when fighting a Terminus, fire your primary as far away as you can to avoid his Axe. Shatterfall is reactable and you can usually scamper away. If not, the momentum you gain should be enough to keep yourself safe.
In close range, depending on their timing of popping their Magic Marks on you, Moji can deal up to 1000 damage per second. Never give her a chance to flank and make sure to focus her down after she pops her Magic Barrier and scampers away.
