I can pretty quickly tell you that your brother should have 23 levels left to grant. Please note that these grantable levels will expire at the end of the 90 day Recruit-a-Friend period. Also, I feel it important to inform you that your brother must spend them before he transfers factions, or realms, or accounts. In other words, have him grant you the levels before he undergoes any of the paid services that we offer. :0)
