Question?

[PercyPichu24]

Just a quick question, finding latias/latios (sapphire + ruby), do i just use a bunch of max repels and go through the grasses? Is there any easy way of knowing where he might be, or is it just luck!

Well the easiest way is to fly to somewhere like lilycove city and go into route 121 and check your pokedex (if have seen it, if you haven't then there is no easy way till you find it once) and if it's not there then go in and out and look again. If it's there. Hunt it down and weaken then repeat. Once it's weak enough chuck ultra balls at it and repeat finding it until you catch it. Although if you have a masterball you can just chuck one at it the first time you see it. If you haven't seen it you will eventually.

Some more helpful tips: Arena Trap doesn't work on them because they have Levitate, but a Wobbuffet's Shadow Tag will keep them in one place. Wobbuffet can't damage them without the risk of accidentally fainting them, but you can start using Wobbuffet once you've weakened them enough to start throwing the Ultra Balls.

Also, when Flying to a city and exploring a nearby route, the chance of success you'll have will be different depending on the city and route you've chosen. Based on the movement patterns of the Latis, probabilities have been calculated for each location, and the best chance you have of meeting a Lati is Flying to Mauville and then going east to Route 118. This is because there are five different routes from which they could move to Route 118. If you do this repeatedly, remember that you must Fly, not walk, back to Mauville before re-entering Route 118 or it won't work as well.

A sufficiently speedy Sableye with Mean Look will trap them. Being Dark is a big help - since they only have Psychic attacks,
