Is your feature request related to a problem?

Consuming thralls seem to be a somewhat unique damage dealing spectre and I believe they could be interesting for the community to play around with if only it was possible to understand how to scale them!

Describe the solution you'd like

Add Consuming Thrall spectre so that it can be selected from pob's raise spectre ability.

Describe alternatives you've considered

Tried adding them to PoB manually with no success.

Inizia dall'abilità Raise Spectre e trova l'elenco degli spectre selezionabili, quindi confronta le voci circostanti per determinare come è rappresentato Consuming Thrall. Il lavoro è completato quando Consuming Thrall può essere selezionato lì e il suo scaling può essere esaminato in Path of Building.
