Goddess ring tends to SUCK it either nulls ALL NON boss encounters if you equip it OR increases your max HP or MP and NONE of those effects are actually useful since in the DQ games that have it you tend to get it after you kill all the post game bosses so even in DQ7's 3DS remake in order to actually GET the Goddess Ring you need 100% monster book enteries which is why its useless. In the DS DQ6 remake its still a post game No enounters accessory but you only get it as soon as you Enter its ONLY Post game dungeon. After you have a GOD party ie the 3 Non hero's have every single Spell and Special skill keep them as your final job one that don't take forever to lv up ie Stay in the Thief class only.
The catch is that HITTING LV 45 in the Sage takes way TOO long even if you use the Metal Slimes in theTower North of All trades Abby itself I prefer learning the white and black magics just by switching the Black Magic user at lv 38 to lv 40 to a White Magic user and a White Magic user at lv 38 to lv 40 to the Black Mage. But in this remake its better to start out with Thief due to the changed Small Medal Locations the Monster class user to do the arena fights ASAP and Player to have it become a Sage at lv 20+.
