You most certainly can have range armor and bow and arrows on Entrana. Like someone mentioned before you just bring tanned hides (dragon or leather) depending on your Crafting skill and a bring log and a bow string with you depending on what your crafting level is. Also bring needle thread and knife. Take boat to Entrna, as soon as you step off boat, make a hide top and bottom and vampbraces with your leather. Use knife on your piece of wood and make bow, string bow, your arrows should already be made so there is no problem with that. Go down the ladder and have yourself a good old time ranging the Greater Demons. Believe me it works I went from level 65 ranged to level 94 ranged down there ranging nothing but Greater Demons. The telegrabbing from the other dock does not work anymore they fixed that a spot a day after it was realized. You used to be able to bring a level 3 clue treasure chest to island and the open it once you got there. I opened several of the on the island along time ago just to see f it worked and it did. Im not sure if this has been fixed or not because I havent tried it in well over a year. Other that the 2 ways I just listed I dont think there is anyway to bring armor onto the island.
