You have an obsession with the study of a specific subject, beast, magic, art, etc...

When in an interaction with your study of choice you become distracted and must spend some time writing down your observations. If you are entering combat you have a -4 to your initiative to a minimum of 0. If out of combat you briefly have disadvantage on your perception checks until you have concluded your notes.

FLAW. This is a flaw feat. At your DM's discretion, you may take this feat at level 1.  If you do, you may also gain a second feat, or increase two of your ability scores by +1 (or one by +2).  If you choose to increase any scores, you cannot choose to increase any score affected by the Flaw.  Some flaws can be overcome in time, with role played work towards that end.  Others might be overcome by a high-level Cleric, but the cost might involve a side quest or a great amount of money.
