If you are at an EM event and there is death and carnage happening everywhere with bodies stacking 4-20high, it is next to impossible to find your corpse...use the staff to retrieve your corpse to your location along with all the items inside it.
1) You were in the middle of looting an EM Event Monster and you have just pulled the Named Item off the corpse and you were killed. Wouldn't you like to retrieve your body before it decayed and thus retrieve your "rare and/or one of a kind" item that you didn't have a chance to insure?
2) You are at an EM event on a dexxer and rely on potions and bandies to stay alive; you end up getting killed and get a rez. Do you want to expend the time to go to a bank or your house to replenish your items and try to get back to the event in time to retrieve your corpse prior to it decaying? OR would you rather, use the staff to retrieve your corpse that is buried under all the other corpses; near a hoard of EM Monsters that is targeting everything or that has an area affect going that does 70+ damage allowing you to continue the fight in order to get a chance at getting a “1 of 1” item?
I use the Undertakers primarily at EM events, so far, so I can get my bandies & potions so I can continue the battle. I have had to use it one time to retrieve my corpse that had my 1 of 10 item on it that I was actually in the middle of insuring when I died.
There have been a few times in the past, at the Event Arc Invasions, that I can see using the staff as well in order to get my dexxers bandies & pots so I can continue the fight without having to go replenish.
Yes, I know...you can HONOR yourself and go retrieve your body. However, the time it takes to dig through the piles of corpses, not knowing EXACTLY where you died and/or the time it takes to go back to your bank/house to replenish is negated by being able to click the staff and your corpse shows up at your feet in seconds is a BONUS and a HALF!
