Rock Slide = 75 power @ 90 accuracy.

Over 10 turns it will miss once, so do 9*75 = 675 damage.
Out of those, 3 will flinch. So you can add 3*75 to compensate.

That comes out as 900. So it's TRUE base power is 90.

Hidden power rock does 10*70 = 700 damage.

This is of course an advantage as Slide could miss at a crucial time.

90 > 70 but a sure hit.

Ancientpower = 10*60 = 600.

Weakest of the three in overall damage, but out of those 10 attacks, 1 will raise your stats. That is better than a flinch imo, it depends on the situation. Increased defenses mean it should survive attacks, allowing a dragon dance type boost in the sweeping stats.

So what do you think? 5 stats increased is the equivalent of two extra attacks: +(75*2) = 750.

But then it will hit, and you have that luck factor.

Rollout is predictable, Rock Throw is inferior to Rock Slide, Rock Blast is nice to break subs.

Hidden Power [Rock].

So you dont get all pissed of when Rock Slide misses.

Welcome to psypoke!

And yes, of course. But, on average Rock Slide does do more. And the chance of it missing are slim.

Misses once: 10%
Misses twice: 1%
Misses second time: 9%

Out of two attacks, the chance of it hitting both times = 100% - the chance of it missing at least once = the chance of it missing once + the chance of it missing both times.

Hit Hit = 1 - Chance of a miss
Hit Miss = 9%
Miss Hit = 9%
Miss Miss = 1%
100 - 19 = 81/100 ~ 4/5
So there's about a 4 in 5 chance of it hitting twice in a row. That's better accuracy than Will-o-wisp and Sleep Powder. Almost as accurate at Toxic.

Sorry if no-one knows a word I'm talking about!

i know what youre talking about, but couldnt you say the chances of it hitting twice in a row is 0.9*0.9=0.81? (just an easier way to arrive at your 81% figure )

my vote is for rock slide - the flinches are just so good. maybe on something slow and robust, HP[rock] or even ancient power might be good, but on something like an aerodactyl rock slide is the best if you ask me....

as for comparisons, it is the same accuracy as leech seed. i think its interesting that rock moves usually have a non-perfect accuracy. i know when i throw rocks at stuff i certainly have a non-perfect strike rate

I am a huge tech fan. Can it beat Blissey with HP Rock or does it need that extra boost? Will the flinch hax be useful? Are you only using it against flyings with Quake as your main attack. Will the extra EVs you have by raising the power and lowering the accuray (but to keep the same damage ratio) be useful for protecting it from a OHKO?

And some people say pok

i had three rock slides miss in a row yesterday. the chances are 1 in 1000!! thats about the same odds as sheer cold hitting four times in a row just to put it all in context, the chances of rock slide missing are practically the same as a OHKO move hitting twice in a row. yet somehow no-one is really ever worried about that happening......

luck evens out though - a couple of games later i flinched a skarmory to death, and someone missed me with leech seed twice in a row.

For me just like this

**** Hidden Power:Standart

*** RockSlide(**** with king's rock):Good power,flinch chance,but can miss when you most need it...

** Ancient Power:Low att,Low pp,Too much haxy...

I think Ancientpower SUCKS! It's a pretty weak (60 BDamage) Rock attack with 5PP. It has a chance to raise all of your stats by 1, but it's unuseful since it's PP is too low. On a GYM battle, yes; Ancientpower is better but in E4, it will be totally unuseful unless you give a couple of PP Up's to it.

When it really comes down to it you should have Ancient Power or Both
(I think)

Yes, why not have an Onix witrh all four rock moves?

<sarcasm>That would be teh ownage!</sarcasm>

No.

Personally I like rock blast because of it´s ability of breaking sub´s. wich is a good advantage in metagame battles where substitute is a common move.

Rock Slide on T-tar, because of flinching (I actually beat an aerodactyl, with a cb-t-tar, flinching it. LOL).

And, Ancient Power only has 8 with Max PP

but the flinch effect can only work if you attack before your opponent. how could tyranitar outrun an aerodactyl? (unless it was baton passed a hell of a speed boost.) besides, rock slide with choice band, STAB, tyranitars huge attack, and aerodactyl's weakness to rock moves would be way more than enough to knock it out. why would it need to flinch???

Agreed. About tyranitar, in D/P, crunch is physical. I've prepared a Tyranitar:

L56 Hasty Speed IV: 31
Crunch
Rock Slide
Earthquake
Dragon Dance

*Checks Netbattle*
360 Atk, 210 speed

Don't ask why I gave it 208 speed EVs. I figured it was CB'ed, so I didn't have to focus that much on Atk. Oh, and in case you were wondering, Adamant nature, 96 Atk Evs -> 360 Atk. CB'd, thats a 540 Atk. I don't know, maybe the person skimped on speed for defense.

the maximum speed tyranitar can have is 243 (+speed nature, 31 DV, 252 EV)

the lowest speed aerodactyl can have is 238 (-speed nature, 0 DV, 0 EV)

so i guess there is a slight possibility your tyranitar could have been faster. but i very much doubt it. at the very least, your opponent would surely have no reason to reduce the speed DVs.

Ancientpower: An attack that may raise user's stats but its PP and BPower sucks. ***
HP Rock: %100 accurate, has 70 BPower, has a lovely 15 PP and you may teach it to anyone. ****
Rock Blast: Good for a counter to Sub-Punchers, plus may do up to 100 BP, but 10 PP for a %80 accurate attack is worse than bad. **
Rock Slide: Has 75 BPower, %90 accuracy, %10 chance of flinching and 10 PP. ****
Rock Throw: Has 50 BPower and %90 accuracy. Compare w/Rock Slide. *
Rock Tomb: Has %80 accuracy, 50 BPower, and 10 PP, but lowers foe's speed. **
Rollout: Has 20 PP, 30 BP, %90 accuracy and lasts 5 turns w/rising intensity. *** (if used w/DCurl, *****)

I'd prefer Rockslide and Ancientpower. They are both good attacks.

I picked ancient power because of the fact that i can wipe out flying pokemon and get all of my stats raised.

Could be either. Rock slide is trash on something slow, because then you just miss all over the place, and you can't flinch anyway. The stat boost from a. power is a long shot too, so i don't think it's worth settling for such low base power. Rock slide on faster stuff like aero, hidden power rock on slow stuff like armoldo.
