Confer Blessing

Confer Blessing is a feature introduced in Version 2.0.0 where the player can use a Blessing to confer a bonus to any non-legendary and non-mythic hero. It can be found under the Ally Growth menu.

Details
Whenever the player obtains a Legendary Hero or Mythic Hero, a blessing for their attribute will be added to the inventory. Unlike Sacred Seals, for which duplicates are not allowed, it is possible to have multiple blessings of the same attribute, and confer each to a different Hero.

Each blessing can be conferred once only, so they cannot be removed and given to another Hero afterward. If you give a blessing to a Hero that has received a blessing in the past, the previous blessing will be overwritten.

Blessings have two effects:
 * Blessed allies receive double the usual amount of SP.
 * Blessed allies receive ally boosts during the blessing's season when a matching Legendary Hero or Mythic Hero is present.
 * For example, entering a battle with a Water-type Legendary Hero (e.g. ) during the Water season grants HP+3 and Spd+3 to all Water-blessed allies.

Legendary and Mythic heroes are not allowed to receive blessings, as they already benefit from double SP. They won't receive bonuses from other allies of the same element, but if the current season has both of their elements, Mythic heroes will receive Legendary Hero effects and vice-versa.

Legendary Heroes
Legendary Heroes are heroes who can grant allies certain boosts during the Season of their element, if the allies have been conferred the blessing of the same element. They have a special icon on their profile screen which shows their Legendary Effect and Ally Boost.
