The time-related limits would do little, because people could just wait that long to scroll again. The limit on how many times an item can be scrolled should be changed depending on the item's level. For example: A level 0 weapon would have 0 slots. Level 10 and 15 items could have 1 slot. 20 ~ 30 could have 2. 35 and 40 would have 3. 50 would have 4. 60 would have 5. 70 has 6. And so on. That way, we don't get crazy scrolled weapons that are faster than their higher-level counterparts. For example, Red Vipers, Mebas, Zecos (I think that's what they're called).
