Marcelline has chosen the School of Necromancy as her arcane tradition.

When Marcelline kills a creature with a spell of 1st level or higher, she regains hit points equal to twice the spell's level, or three times the level if the spell belongs to the School of Necromancy. This does not affect constructs or undead.

Marcelline can transcribe spells from other spellbooks and magical writing into her own spellbook at half the normal time and cost.
