Return an Open or Closed [subtype: Beltorat Kingdom] unit to the File. You get SP +[unit's base level]+2. You cannot Set units except [subtype: Dragon Kin] of LV 7 or lower until end of next turn.
Actually the non dragon kin units are locked for two turns instead of only the next turn as stated on the skill. Either this is a bug or the text is wrong, in both cases this needs to be fixed.
Thank you for correcting this.
