Cursed!
I’ve found an interesting article written by Master Ed Greenwood about curse of the Forgotten Realms after the Sundering.

• The House of Velarr
• Althur’s Spidergout
• Balarthran’s Recurring Profanity
• Cloahkaudra’s Follicular Fury
• Hanra’s Leaking Liquescence
• Jarrakal’s Hallucinations
• Jonatha’s Clumsiness
• Metalbane
• Zult’s Unquiet Slumber

Here the full description of these curse spells that you can use instead Bestow Curse spell :
