Scroll of Enchant Weapon: Each Neutral Scroll of Enchant Weapon will enchant a weapon by increasing the damage of a weapon by +1. Example: Gradius does 9/11 damage, if you enchant in once with Rose Zulie a Neutral Enchant Weapon scroll its damage will be 10/12 (10 to small monsters, 12 to large).

A Blessed Scroll of Enchant Weapon will increase the damage of a weapon by 1, 2, or 3 randomly. You will want to use this as the last enchantment of a weapon before it reaches its maximum level of enchantment. For more info, see the guide below.

A Cursed Scroll of Enchant Weapon will decrease the damage of a weapon by 1. This is used in the situation when the blessed scroll only increased it by +1 and you want to try again to get +2 or +3.

Weapons: Weapons can be safely enchanted 6 times. If you would use only neutral scrolls, you could get a +6 weapon safely.

However, you can get a higher + if you use a blessed scroll in the end. If you choose to do so, enchant to +5 with neutral scrolls, and then use the blessed scroll to get a +6, +7 or +8 weapon. There is no such thing as elven weapons. All weapons should treat the way it is described here.
