Blessings grant unique skills and buffs that your character can unlock to be more effective in combat. You can access the blessings tab under skills on the "Main Menu".

How can I obtain Blessings?
As you progress through the story, you will obtain Memory Fragments which can be used to unlock Blessings. Once you obtain a Memory Fragment, the questline to unlock the rest of the Blessing will appear and notify you of the remaining Memory Fragments.

Once you have obtained all of the Memory Fragments for a Blessing, travel to the nearest "Altar of Physera" to unlock that "Blessing".

What are Skill Points?
SP (Skill Points) are used to unlock skills and their corresponding buffs. These points can be obtained by leveling up the Skill Level of the Character or by obtaining SXP from completed "Campaign Quests", "Side Quests", and "Region Quests".
Once all of the skills and buffs of a Blessing are unlocked, a passive bonus is granted to the character (even when the Blessing is no longer equipped.)
Each blessing offers a different skill-set. You can replace your currently-equipped blessing by praying to one of the many "Altars of Physera" scattered across Lumios. You can find them by tracking their logo on the world map.

Obtaining new blessings is essential when it comes to strengthening your character. In order to unlock a new blessing, you need to gather memory fragments from defeating unique field bosses, completing dungeons, and achieving a certain level of reputation with the factions of Lumios.
