No Encounters

[jjturtle12]

I think you need a bunch of Purifying Salts, for your armor, but somehow I found a devastator (weapon for Rikku) that had this ability. So weapons can have it.

I also have Rikku's no encounter weapon, and I think I had one for Tidus and also for Wakka (although why have more than one?). These all showed up in the Omega Ruins, along with some no encounter armor. It made doing the tasks in the Omega Ruins easier earlier in the game.

If you're into capturing monsters, this is a pretty easy way to get 99 Purifying Salts, 30 of which you can use to add the ability to someone's armor:

For the Monster Arena, you need:
>>> Vouivre [Mi'hen Highroad] x4
>>> Lamashtu [Mushroom Rock Road] x4
>>> Kusariqqu [Thunder Plains] x4
>>> Mushussu [Sanubia Desert] x4
>>> Nidhogg [Cavern of the Stolen Fayth or Mt. Gagazet] x4

in order to get 99 Cleansing Salts.

It seems like it would be cool to equip the No Encounters and HP Stroll abilities onto someone's armor and equip it if you wanna heal the character but don't wanna use a save sphere/potions/magic.

Edit: Just checked the date of the original post...hopefully you've gotten it by now
