Done Haze should clear focus energy in Gen 4

[RadVik]

What type of bug are you reporting? Mechanics

What is the bug?
Haze does not remove the effects of focus energy. Example here. https://replay.pokemonshowdown.com/gen9ou-2360003811

Bulbapedia says it should here: https://bulbapedia.bulbagarden.net/wiki/Haze_(move)
"

Generation IV onwards​

Focus Energy effects are again lifted by Haze.

If powered up by Icium Z into Z-Haze, the user regains all of its HP."

I do not own a modern gen pokemon game so I cannot verify the mechanic in-game myself, but I generally take bulbapedia to be a reliable source. Is there something I'm missing? This interaction is actually extremely relevant in the new omotm Trademarked, so I would appreciate a fix or clarification if Bulbapedia is wrong. Thanks!

Are you able to replicate it? If so, how?

Here focus energy plus a high crit rate move is used repeatedly vs haze. Every single attack being a crit, as well as the tag of focus energy remaining in place, suggests that the effect is not removed.

While mechanically fixed, client will need to be updated to follow expected behaviour

It's way too hasty to implement this just because Bulbapedia says so. It looks like the edit happened here and they do not provide any source for their information.

Here's a quick video showing that Haze does not remove Focus Energy in SWSH.

It was also recently brought up here that Haze doesn't remove Focus Energy in modern generations, so there needs to be research to prove this is the case.

If we want to be thorough we should check generations 4-9 (excl. 8 since its tested above) and go from there. Its possible it changed sometime between 5 and 8 and isn't reported.

In the future please do not use bulbapedia as a source for mechanics changes without verifying their accuracy first because anyone can edit those pages, we don't want to waste your time programming a fix only for it to be rejected. This is also why the bug is flagged as Needs Triage still, though you are welcome to ask in the dev discord for us to take a look at a report in case it was just missed (not checked).

I did some testing. The claim that Haze clears Focus Energy is true in gen 4 (DPPt and HGSS).

I tested Emerald, Black, X, US, SW, SP, LGE, and V after that and none of them let Haze clear Focus Energy.

So it's a gen 4 only thing, then?

I did not test gen 1 or 2.

 

[metagrossEnfusiast]

Should I modify the fix to be Gen 4 specific only then?

That sounds like a good plan to me.

Looks like a Bulbapedia admin also tested gen 3-9 and came to the same conclusion: it's Gen 4 only.

I guess Gen 2 is really hard to test compared to the others.

It's not particularly difficult, it's just not usually worth going through the trouble with a disassembly readily available: https://github.com/pret/pokecrystal/blob/master/engine/battle/effect_commands.asm#L6002-L6023
(Gen 2 also only resets stat stages)
