When gaining a new attunement slot, the slot may become unusable if a spell is not immediately attuned. Bountiful Sunlight, Chaos Fire Whip, Chaos Storm, Great Chaos Fireball, Soothing Sunlight, Sunlight Spear, Pursuers and Vow of Silence require two attunement slots each.The Darkmoon Seance Ring and White Seance Ring each grant one additional attunement slot, and can be worn simultaneously.No additional Attunement Slots are granted past 50 Attunement, capping the total number of slots at 10 (12 with both rings equipped).
(Keep one open because crystal soul spear requires 2 and you can't free up a lot well, not with out re-attuning. I sugest having a Side weapon to buff as for attunment you will probably want about 4 Attunment slots. Higher numbers of attunement slots enable more magics to be cast, with attuning multiple copies of the same magic allowing for more total uses. As for attunment at 50 intelect with Crystal soul spear, you will be 3 shotting pretty much everything in th evanilla game. 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.
