Balrog shoe scrolls

Can anyone post what scrolls does what? There's different options to turn in x number of leathers for a scroll, and I don't know which gives what, and it would be helpful to know.

Current leather exchanges :

1 leather : 30% def scroll (wasted a leather )
7 leathers :
20 leathers :
30 leathers :

I would like to know this also. I know that cyanne had that guide thread. I think she was posting updates while she tested what she got when exchanging leathers.

edit:

You can trade 1, 7, 20, or 30 balrog leathers in at once to the NPC in the map directly above the lobby. You cannot access that map if you warped there through Manji, the portal is only accessible if you originally came from that map. In my experience, trading one at a time only rewards balrog defense scrolls, so I don't recommend you trade once at a time. I'm guessing that 1 leather gives defense, 7 leathers gives hp/mp/speed/jump/acc/avoid, 20 leathers gives str/int/dex/luk, and 30 leathers gives twilight, but I haven't gotten enough leathers to test the higher numbers yet.

also, what is twilight?

These are scrolls for the balrog shoes. STR, HP, and Speed ones are untradeable, all the others seem to be. They ARE NOT cursed.
30% STR +2
30% INT +2
30% LUK +2
30% DEX +2
30% Max HP +30
30% Max MP +30
30% Speed +3
30% Jump +5
30% Avoid +5
30% Accuracy +5
30% Weapon Def +10, Magic Def +10
5% STR +4, INT +4, DEX +4, LUK +4, Speed +4, jump +4, Accuracy +4, Avoid +4, +14 physical defense, magic defense +14, MaxHP +40, MaxMP +40

I assume twilight is the bottom one.
