RDPateau 29 Jul 2021 14:46

For those going in thinking this is daunting, bear in mind that gen 1 catch rates are kinda janky. Lowering health will only increase the catch rate by ~3% regardless of status condition, while putting to sleep will bump the catch rate up to ~21% even at full health

was jancked for me catch that mustard pokemon...

Did this in about 5 ultra balls with a Level 64 Lapras. Use Ice Beam to lower its health and pray you manage to freeze it. If you do, your chances of catching it are pretty decent

My Lv53 Jolteon with thunder wave, then a wild Lv64 chansei for lightscreen, then jolteon for thunderbolt, then lots of fullrestore and ultra balls.

That was easier than expected but maybe I got really lucky. My strongest Pokemon was only a level 50 Jolteon, but I used Thunder Wave and Sand-Attack x6 to try to stay alive, and weakened him with Thunderbolt while he spammed Recover. Eventually he stopped recovering and it only took 4 Ultra Balls to catch him.

Don't bother weakening him at all, it gives almost no increase in catch chance, a status (preferably sleep or freeze, paralysis is good too though) and then ultra balls is the way to go. Here are some odds to show why (all use Ultra Balls):

Full Health- .526%
1/3 health or lower - 3.74%
Full Health Frozen/Asleep - 21.634%
1/3 health or lower Frozen/Asleep - 23.752%
Full Health Paralyzed/Burned/Poisoned - 11.594%
1/3 health or lower Paralyzed/Burned/Poisoned - 14.493%

This is true of basically all Pokemon with a low catch rate, status is the way to go and damage is a waste of time.

apply was a rng catch,example: press any button before launch a hyper ball to mewtwo with the % point sample of 14ausher,is probably you catch that pokemon using the method rng and % point xd
