Reliable source of shards in ORAS?

Question

Is there a way to reliably get shards as well as stones ORAS? I cannot seem to get Fire Stones and know about the "Pick up stones" secret pal ability.

if you have x or y and pokebank just send them over to that and buy them from the emporium if you need fire/leaf/water

Answer 1

You can also visit mirage spots each day. Use the dousing machine to find the hidden item and sometimes they'll be one of the 4 shards (the hidden item resets each day along with the mirage spot)

Answer 2

The only repeatable source of shards in Omega Ruby & Alpha Sapphire is going to be various Mirage Spots. All the other locations are 1 time only.

Here's a detailed tutorial on every shard location, and you'll see the only repeatable options are these Mirage Spots:

Red Shard = Mirage Caves (any)
Blue Shard = Mirage Caves (any)
Yellow Shard = Mirage Mountains (any)
Green Shard = Mirage Mountains (any)

The shard will always be a hidden item and there's only 1 hidden item on the 1 mirage spot available each day. But if you keep checking daily with the Dowsing Machine you'll be able to acquire as many as you want over time.
