When an adventurer moves into a hex on a tile with a skyshard, they immediately gain that tile’s skyshards and resolve the tile’s skyshard effect; this interrupts the adventurer’s action but does not end it, similar to a lockpick check.
Place the skyshard card near the delve encounter text to show the total number the party has gained. Some cards may grant more than 1 skyshard. If these additional skyshards exceed the maximum for the current delve, they are ignored.
