Catching Feebas and Milotic
I highly recommend catching Feebas for these three reasons -
1) To complete the pokedex
2) For some bragging rights
3) To obtain a Milotic which is has great Special Attack and Special Defense, along with a great move pool.
What You Will Need
1) old/good/super rod [old is preferred as Feebas can be caught with it, but you don't have to waste time with other pokemon besides Magikarp and a few Tentacool. It can be obtained by a fisher in Dewford town. He stands near to the gym]
2) approximately 5 pokeballs [higher grades are not nessary for such a weak pokemon] as you will want to catch a few feebas.
3) a pokemon that knows surf [HM slave ^_^]
4) a pokemon that knows fly [not a must but after sitting in that water for so long i would think u would want to get out of there as quickly as possible]
Feebas is a rare little fish pokemon. How rare you ask??
Well let me see. It is obtainable in 6 tiles [sections of surfing water] out of approximately 400 tiles of surfing water on route 119.
Now thats something isn't it??
The feebas tiles are random and if you change the "Popular Phrase" in Dewford town the tile positions are RANDOMLY RESET[ie you can't take someone else's 'popular phrase' and try fishing where they got their feebas. It won't work.]
Now that you have what u need head up to the base of route 119. Do this by flying/walking to mauville and then surfing across the narrow stripe of water right of the gym.
Now you will be on route 119. This is a very long route [unfortunately] packed with sections of water [potential feebas grounds] along its length. I recommend you start form the first pond you come across. Start form one corner and work your way up. Fishing in each tile you move into.I recommend fishing 3 - 5 times in one tile as any less may allow our fishy friend to slip through and any more would be overkill.
Now all this sucks i must admit, but when u do find the feebas tile you will be pleasently surprised to find that they will appear with a 60-80% probability. Which is, in my opinion, fairly sweet.
Evolving Feebas
Well now that you have feebas you must be wondering - "I hate you Ice Demon. This thing is ugly!!"
Thats why we need to evolve it.
To evolve feebas you need to get its beauty rating to 170. To do this feed feebas blue/indigo pokeblocks. However you will only be able to feed Feebas 12 pokeblocks thats why these factors below are important -
1) personality of your feebas - The way a feebas responds to a pokeblock is determined by their personality. It is recommended that you use either one of these personalities :Rash, Quiet, Modest[the best as it increases SpAtt and decreases Attack,which is an important quality for all milotic],and Mild. If you get a feebas with an Impish, Careful or Adamant[like anyone will want those personalities XD]don't bother.They hate dry blocks [which blue and indigo are] and so will require high grade berries to make their pokeblocks which is difficult.
2) The grade of pokeblock you use - level 11 blocks can be obtained from : Weaper, Lum, Oran, Chesto and Bluk berries [these are the lowest grades]
level 23 blocks can be obtained from :Wiki, Kelpsy, Hondew and Cornn berries [these are the best type of berries as they are more effective than lvl 11 berries but are easier to obtain than lvl 45 berries
level 45 blocks can be obtained from : Pamtre berries [the highest grade berry]
Berry types A and B can be found throughout Hoenn. However a popular destionation for most trainers is the "berry masters house"
To get there surf down from mount Pyre and you will be in route 23. Follow the route and you should eventually reach the berry masters house. Or you can surf right from mauville but instead of walking up through route 119 go straight and you will reach his house.
The berry master gives you berries. To obtain the berry u want save before you talk to him. Keep restarting and talking to him until you get the berries you want.
PS to get pokeblocks you need a pokeblock case which can be obtained from a little girl in Slateport City in the Contest Center there.
To blend berries go to anyone of the Contest centers and blend with the old man on the side of the screen.
Feed Feebas the 12 pokeblocks and lvl him up. You should now be a a proud owner of a milotic.
