This is a fantastic resource, thanks for all your hard work.
I noticed with Remote Spellcasting you mention verbal and somatic components. Could I recommend you change it to:
Remote Spellcasting. The Khan can cast spells that do not require a material component through this golem.
or even...
Remote Spellcasting. The Khan can cast spells as though they originated from this golem.
...simply because SD doesn't have the concept of spell components in the same way as other D&D-style RPGs.
