No additional Attunement Slots are granted past 50 Attunement, capping the total number of slots at 10 (12 with both rings equipped). Higher numbers of attunement slots enable more magics to be cast, with attuning multiple copies of the same magic allowing for more total uses. Each attuned magic has a limited number of uses that can be restored by resting at a bonfire. Attunement is the stat determining one's number of attunement slots available for Pyromancies, Sorceries, and Miracles.
