What the letters mean
Race, class, and trait letters follow the printed bonus lines on the same roll menu. A higher rarity is usually the better hold. Merchant is the exception worth keeping for Yuls. Grimoire letters follow reported move variety for the launch 10 and will move when Update 1 books have names.
S tier
Player decision Keep and build Power. Pair with Devil before you chase another book.
Player decision Keep if you do not have Anti-Magic. Strong into bosses that punish melee.
A tier
Player decision Keep over the commons. Do not delete it for Fire or Earth. Recheck after Update 1 before you treat it as finished.
Player decision A practical keep for mobs and single targets until a Mythic appears.
Player decision Keep as a control book. Do not expect it to replace Poison on Magna.
B tier
Player decision Good early and in a squad that needs a pin. Unlock the 50-point stun before Sosshi.
Player decision A real starter. Plan to replace it before the level 75 bosses.
Player decision Usable while you farm crystals. Not a final hold.
C tier
Player decision Replace when any Uncommon or better book appears.
Player decision Replace first. Keep it only until the next crystal.
