See [lore]Item Enhancements[/lore]. Also, I'll soon have a page up on LORE detailing the Bow Training system.
Don't think it'll be stickied anywhere. As gathered from other similar posts (any crafting) the only ones that post such are guilds with their information. I myself have a Layo FOlder and already had such information written down or I post a link in my Favorites. And with all the combinations of heads, feathers and shafts, it would be quite a job working out the lvl requirements for each. Best bet is if you know a char that makes and shoots their own arrows, ask them to use the gizmo to see what lvl they are and their components. But never have I seen a sticky with a breakdown of somethings components, lvl and abilities outside a post made by a guild.
Just thought you might want to add the following: Adamantium - Extra damage to outsiders Titanium - Extra damage to giants Mithril - Extra damage to dragons
If I remeber to reasearch this IG, I can make a level req table for the arrows later. I need to add the enhancement lvl req table to LORE somewhere anyway.
