If you lose an HM, you can get it again where you got it the first time.
then all your Pokemon will die
Yahoo it;)
you must have dive move or dive TM with you you can get it at the end of the game.. cheers
On the 10th floor of the Solar Cave is where you can find a Dive HM. I recommend teaching it to one of your pokemon. Whooper is a good one if you have him. You'll need a key. Bring an escape orb just in case you get in trouble.
Silver Trench on floors 65 thru 79 be sure to bring a water pokemon + Hm Dive
From Wish cast after you defeat groudon in the magma cavern. Hope it helped:)
To get the hm dive you have to beat raquaza and and see the credits then you go to wiscash pond and wiscash will give it to you.
Wishcash after you beat raquaza and a bit further in the story
Try the 10th floor of Solar cave. Next time, you might want to try teaching it to one of your pokémon (i picked Dragonair)
Heh, that's what happened to me! Well, you've gotta go to Solar Cave, bringing along a key, and on the 30th floor go and open up the chamber, if you don't have Dive anymore that's what it'll be. Note:You can do this as many times as needed when you lose Dive. ~PikiSkymin.
In stormy sea (Dive is needed) , Waterfall pond (waterfall is needed), and other area's with water.
you can't clone in red rescue team
