I've got a quick question...
Do you need a Roselia to breed Aromatherapy to Chansey?
Yes. Roselia is the ONLY Pokemon in the game that can breed Aromatherapy to Chansey.
That would blow if you do, seeing as how I don't have Ruby, and I can't seem to find it anywhere but online for insane prices.
Roselia can be found in Sapphire too. Methinks you are forgetting that Chansey can also learn Heal Bell as an Egg move. It is basically the same as Aromatherapy, but is subject to the Soundproof Trait. You can breed Chansey with Skitty (Lv37).
Also, I got my Blissey (without Aromatherapy, mind you), and it has Serene Grace, that promotes additional effects. So that said, I have this moveset (I also boosted Blissey's Special Attack with EVs):
Nature: Bold (of course)
- Heal Bell
- Softboiled
- Thunder Wave/Seismic Toss
- Ice Beam
Ice Beam and Softboiled are musts, but I'm open to change Refresh and Thunderbolt. I figured Thunderbolt for the added chance of Paralysis, and Refresh to make up for the absence of Natural Cure and Aromatherapy.
Serene Grace is nice, but I would go with Natural Cure, since most often your opponent will try to status your Blissey. I did run a special sweeping Serene Grace Blissey in-game once that was pretty effective (Blizzard/Softboiled/Thunder/Water Pulse). 40% Confusion with WP is pretty cool. Refresh is pretty pointless here as the true value of Aromatherapy/Heal Bell is that it cures your ENTIRE TEAM of status conditions. Refresh will only cure itself, which Natural Cure already does. Thunder Wave or Seismic Toss are standard for a reason. TW for obvious reasons, and ST allows Blissey to inflict consistent damage.
Anyways, I'm so excited... in 15 minutes the Master Blender comes, and then it's Milotic time! (I tried to wing it and blend berries with the Mister, but their power wouldn't cut it... so I bred a new Feebas, and have been waiting almost 4 or 5 days for the Master Blender.)
The Secret Base trick works well, but if you have Pokerus and Macho Brace, you can fully EV train a Poke in under thirty minutes. I think I fully EV trained my Blissey in 20 minutes. But the base trick is great for a giant boost, and then fill the gap with wild battles. But for me, I don't have the patience to restart my Sapphire 12 times just for an EV boost... it's just as easy to battle wild Pokes. Maybe one day when I get motivated I'll start adding EV bases. They are great for experience, though. haha, get a Level 100 poke who only knows Leer or something pointless like that. May take a hell of a long time to take him down, but imagine the experience for a Level 5er (or similar level)!
