Load her down with company swag, hidden in her inventory. Couples fruit, pickup line, paralytic poison, anything else erich can’t think of a use for
Give her the disposable bindings; company stamp and rune of entrancement.
Feed her 1-2 necklaces a day and have her use them for bribes and/or gifts. At the very least jewels of discord will make sure the two ladies of the house Barov want them.
Have Melisara on standby to teleport directly into her body; she can’t be there full time, but if Lillibeth needs rogue skills Melisara can provide.
Equip her with items that will make her better at magic. Robes, staves, that kind of thing
Kill. Kill your enemies en masse and raise them in the masters name. By which I mean power level Lillibeth to level 6 as a dark ranger first, giving her a powerful instant charm spell usable on anything beneath a certain threshold of power, 4-5 times a day if mana allows
We just got a mission that will happen inside of the Scholomance; hold off on sending her until we do that?
10 credits: Social talent sharing- turning our little former ghost into the queen bee of necromancy hogwarts is very plausible
10 credits: covert talent sharing- if she’s going to be proactive beyond making “friends,” she should probably be better at sneaking and lying.
10 credits: soul talent sharing- if she’s an exceptional student she will get more attention, positive and negative
20 credits: purchase Illucia or Jandice Barov. They shouldn’t be too hard to capture once she establishes herself, but having a woman on the inside would make this way easier
