Lost Arts (ロストアーツ) are a set of spells cast through particular quartz created during the Dark Ages that consist of multiple septium gemstones. Their enormous power combines the power of three different elements together. Thanks to similarities in orbal wavelengths, the Lost Arts can be cast inserting the corresponding quartz in the ARCUS. It can only be inserted in a element-locked slot that corresponds with one of the three elements of the quartz.

In Trails of Cold Steel II, Lost Arts can be found in the second half of the game by defeating Cryptids. Each Art can be used only once per battle and will consume 100% of its user's total EP. They return in Trails of Cold Steel IV and Hajimari no Kiseki additionally granting large stat buffs. In Hajimari's extra chapter, the lost arts can be upgraded to give larger stat boosts.

Trivia

  • The 'The Dragon' and 'The Holy' cards from CS2 are replaced with 'The Ice' and 'The Heaven' in CS4, respectively. However the art remains mostly the same on each card with only the colors and background changing.
  • Hajimari no Kiseki replaces 'The Heaven' with the 'The Hades'; however, the art, animations, and descriptions are completely identical. 'The Heaven' remains in game, but is given completely new art and animations.
