Units - What's up with these things?

[RAmarAssassin]

(Sorry if this doesn't belong here, and I used the search but nothing came up.)

I don't get Units. I know what they do, but how come I can never equip them? I've used a couple before, but after un-equipping them, I can re-equip them again. And I could really use them too...any help would be hot. http://www.pso-world.com/psoworld/images/phpbb/icons/smiles/icon_smile.gif

Units can only be equipped on frames/armor that have SLOTS. The more slots the frame/armor has, the more units you can equip. One per slot. They are good for boosting stats. Such as a Knight/Power will raise your ATP by 5, things like that, very useful. Makes you consider taking 4 slotted armor more than the next higher defence armor...

once your armor has slots, then goodis are there to be used and boost you and make for a happy character!

just go into your equip option under items once you have armor with slots to add them in
