Obsidian Coldain Insignia Ring

Steps

 * 1) Get a pristine rhino horn - the Bronotherium Patriarch in Great Divide (ring war area) will update this step (heroic encounter)
 * 2) Get 3 petrified treant twigs - Dropped by Petrified Ancients in Forgotten Pools
 * 3) Get 5 sharpening rocks - ground spawns in the Velinoid Caves in Eastern Wastes
 * 4) Scribe the Coldain Chipper recipe (level 2 artisan required) and get 1 glowing sandpaper and craft the chipper on a woodworking table. Return to Malidain.
