How to get D4C

Not an Arrow Stand. You merge the Heart of the Saint's Corpse while you have no Stand.

  • Obtained by: merging with the Heart of the Saint's Corpse while standless. - After merging, you can only destroy the Heart that is merged.
  • Passive: Dimensional Swap
  • Evolves into: D4C -Love Train-

What it costs to build

D4C needs 30 skill points to finish its tree — separate from the 77-point player tree you share with every other Stand. Stand trees are per-Stand, so points spent here do not travel with you when you swap. Because it has an evolution, do not roll away from D4C before you use it. The route is D4C -Love Train-.

Hit split and cooldowns are the numbers on the official card. The board does not publish damage, so a longer move list is not a damage ranking.

D4C -Love Train-

D4C comes from merging the Heart of the Saint's Corpse while standless (30 points). To reach D4C -Love Train- (41 points) you must equip and merge with all Saint's Corpse parts while D4C is equipped.
