Question: what are attunement slots in dark souls?
Answer: Attunement is the stat that allows the use of spells, alongside Intelligence; basically, attunement is how many spells (sorcories, miracles, or pyromancies) that you can stock at once, which you "attune" at a bonfire once you aquire them. Attunement grants 1 slot at 10, and 5 slots at 19.
