Tears in The Veil

There are four tears in the Veil, despite how it says you only need to mend 3. Each time you touch one of the Veil Tear Apparatus (after killing the 3 desire demons that guard each one) it teleports a chest back into the real world that you can loot. Once you get back to the real world Blackmarsh, the chests hold pieces of the Sentinel Armor set, which is definitely worth putting effort into! All of this must be done before you go to the center of the town, as there is no going back if you missed one.

Once you mend the tears, be sure to hit all the tears back in the marsh (that were once blocked off with green energy barriers.)
