Formula: 250 + 80% of ATK + 600% of INT. The result is the raw amount described by this Demo record before target defense, resistance, difficulty or other live-game modifiers.

When X Bomb Stone is useful

Job in the pouch
  • Solve a field mechanism or traversal problem while preserving normal combat slots.
  • Activate it at the obstacle or route branch so a timed effect is not wasted during approach travel.
Build around it
  • Pair the required field tool with one recovery item and one answer to the area's common status threat.
  • Do not assume the combat formula is the item's only value; several records also open a route or remove an obstacle.
  • Field function: Destroys brittle stone walls.

These recommendations interpret the confirmed effect as a player decision. They do not claim a hidden cooldown, inventory limit, acquisition route or balance value that is absent from the record.

How to use it in an Item Pouch

  1. Name the route problem: decide whether this slot answers recovery, status, combat or traversal.
  2. Check the live inventory: confirm that the item is owned and available before the quest starts.
  3. Place it within reach: do not bury a time-sensitive cure or field tool behind unfamiliar controls.
  4. Review after the run: remove the item if the expected threat or route mechanism never appeared.
