Here is a list of the Destroyed machines still needing to be rebuilt on Abandoned Island.

Destroyed Ore Refinery (18038,24572) 100% Completed. (Near Iron and Silver)

Destroyed Gemcutting Structure (17679,24552) ) 100% Completed. (Near lots of Tier 2 Gems)

Destroyed Tannery (17646,24860)100% Completed. (A few Deer in area by Channeler)

To get to the Ore Refinery and Gemcutter you have to follow the path under waterfall (17388,24714) up the mountain to the Tunnel (17561,24779) go thru the tunnel to snowy paths and follow path up and around. This is a great spot for a Tier 2 Jeweler as the Gems and Silver are right near each other. On the mountain in the snow there are Frost Ogres (Lv24ish), Snow Pygmies (Lv26ish),Snow Ogres (Lv29ish) and Winter Wolves (Mid Lv20's).

The Tannery is on ground level past the Essence Channeler which has like 6 Deer near it.Kinda low priority to finish.

There is lots of Tier 2 resources on the Island with repaired machines. There is a repaired Stonecutter, Logging Camp and Essence Channeler. The Elm and Pale work can be done right on the Island itself. Its also a great confectioner spot with all the Tier 2 resources you would need.

To attune to the Abandoned Island port to Kenaf Port from Brustigo. Then headeast and north out to the end of the Island there at about 14350,18200 you will find a cave. Go in cave and thru the Portal there. Then greet the Gatekeeper and Attune here. Once you have attuned you can port to the Abandoned island from any Racial city for free.
