Sword Art Online: MD – How to Unlock Skill Slots and Stats Per Lvl
Here’s a list Skill Slots and their stats or effects per Lvl. Skill Slots are extra stats that can be unlocked once the requirements are met, upgrade them to get added stats, buffs, debuffs, and other useful effects for your characters. Skill Slots (I guess), are mainly used by game devs to buff up or re-balance characters as the game goes, so even a 5* or 4* character that is in a disadvantage could become more useful with Skill Slots.
– First, you need to unlock the required Battle Skills from your character’s Attribute Matrix, then upgrade them to max level if needed. – Collect required materials (rarity varies per item). – Collect from daily or limited events. Farm them too from story mode stages, refer here for a list of stages and their guaranteed drops: Shards, Crystals and Holy Farming Locations – Void, Fire, Wind, Earth, Water, Holy, and Dark Medallions drops from various limited events. – Available Medallions depends on the current featured event.
– Knight’s Medallions for example can only be obtained from limited events. 
– Rare materials like Sword Dance Medallions, can only be obtained from Ranking Events (1st~3rd place rewards).
– These Medallions, are the only way to unlock the Skill Slots of exclusive characters from Medal Scouts. Highly recommended that you keep them until a strong unit appears.
– Rainbow Essence – Rainbow Candybox – Limited Events – Quest Completion Rewards (check Missions List Section). – Score and Ranking Rewards (Limited Ranking Events, aim for 1st, 2nd, or 3rd to get rare materials). – Drops from various Limited Event Bosses, check event details for more details. 
– Available from the Menu > Exchange Shop
– Collect Stardusts from limited events, then exchange them with Skill Slot Items from the Exchange Shop. Note that limited items will refresh after the expiry date, so save your Stardusts until an item that you need appears.
– Fore more info, refer here: Item Exchange Shop Info and FAQs

-*Note that these upgrade caps will be lifted higher as the game goes, but only the game devs knows when.

– Increases damage done, some SS3s will also get a faster animation speed once learned. – Increases SS3’s damage output. – Increases Attack and Movement Speed, which will also affect MP gain, parry speed, dodging speed and DPS. – Gets a faster SS3 attack animation. – Reduces animation lags or casting time. Some will get reduced damages though due to re-balancing issues (I guess). – SS3 will get an increased number of hits which will generate more damage output. Additional hits depends per character. – Decreases the MP required to cast SS3, this is will greatly affect SS3’s damage output and MP cost. – SS3 will get a new element, but DPS will somewhat drop due to re-balancing, to avoid getting it too overpowered against a certain element (I guess). – SS3 will get a nice support debuff. – and more SS3 enhancements, like Homing Bullets!
