How do I capture Regirock in Sapphire?

So, I have been trying for a long time to capture regirock. I have burned up thousands of dollars in super/hyper potions trying to use a timer ball to capture him. I have tried chucking a bunch of ultra balls at him and it still it will not work. He always breaks out immediately. I want to save my master ball to capture latios and I am unsure what to do.

Here is my team…

Kyogre lvl: 47Moves:Body SlamCalm MindIce BeamHydro Pump

Graveler lvl: 36Moves:MagnitudeRock SmashDigStrength

Regice lvl: 40Moves:Icy WindCurseSuperpowerAncient Power

Sableye lvl: 40Moves:Shadow BallFaint AttackFlashNight Shade

Swellow lvl: 47Moves:Steel WingAerial AceWing AttackFly

Tenacool lvl: 26 (Just for the HM’s. I don’t use it to attack).Moves:DiveSurfWaterfallBubblebeam

Any help will be appreciated since I have been trying to do this since Saturday.

thank you!

What you need is a False Swipe user. Also, so you don’t have to keep buying new items, save before you battle Regirock and reset if you fail.

If you chose Treecko, you can teach Grovyle / Sceptile False Swipe. If not, you’ll have to use a Nincada / Shedinja / Ninjask, but they’re weak to Rock (I believe Regirock has Ancient Power and Rock Throw).

Once you get it down to 1 HP, start throwing Ultra Balls. When the time comes, use a Timer Ball (if it keeps breaking out, of course).

Hope this helps, and good luck! :)

I assume you must be weakening the thing before you try to catch it, right? If that’s the case, there isn’t anything you’re doing wrong. The only thing you can do is keep attempting and just be patient. You’re probably just unlucky. Some legendaries can take hours of effort if unlucky.

(also are you sure that’s a Taillow and not a Swellow?)
