Say a Druid multi-classed...
... leaving the Druidic Path forever and following another path.
( obviously, depending on a successful CDQ and Well-kept CDT )
Does the spells available as Druid get removed?
Ie... are they no longer able to cast Druid spells... or keep any perks from their Druid lvls?
Or are the spells kept?
Or... are they forced into a rebuild?
