Weapon Bond. Analastra cannot be disarmed unless she is incapacitated.

Spellcasting. Analastra's spellcasting ability is Intelligence (spell save DC 14, +6 to hit with spell attacks). She has the following spells prepared:
Cantrips (at will): blade ward, chill touch

2nd level (2 slots): shatter

Rapier. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:  7 (1d8 + 3) [piercing] damage.
