The 
ALL-ROUND (kanji 全) attribute is also referred to as None in in-game files (not to be mistaken with None weapon type), and is sometimes simply referred to as All (not to be mistaken with All weapon type). In the story, it is associated with users that bear many souls and/or memories. It is a special attribute (which consists of All-Round, Infernal, Valiant, and World attributes), which means it shares the same reserved spot in the outgoing Support Lineup as other special attributes. Unlike cards of other attributes, All-Round cards do not have damage multipliers when facing other cards of specific attributes. It can also be thought as All-Round cards having the same multiplier for all cards, as indicated in the table below.

All-Round cards do not apply or receive extra damage from any attribute, including their own. All-Round boosts are obtainable in Daily Quests on Saturdays and Sundays and limit break materials are obtainable in Daily Quests on Mondays JST. They are also obtainable in certain free quests.
Card Attribute
Limit breaking a card requires power stones and spell tokens that match the attribute, and leveling is optimal when the boosts also match the attribute. A full list of cards with All-Round for their attribute can be found here.
AR Card Limitation
AR Equipment can only be equipped on cards that match its limitation criteria. All-Round attribute is one of the potential criteria.
