That templet would be fine in: Doom, The Dojo, and the mines. Some get by just fine without stealth in those places. Just in case you want to move points to some other skill what ever it my be.
I am one of the ones that do use stealth though. It helps ME in a number of ways. The first way is when you get to a place where there are a lot of stealable items there can be a lot of spawn. A good example is in doom at the table. In that area you can find the:cocoon, egg case, streatched hide, saddle, hanging legs, the tunic and the brazier.
If you have a number of thieves running by to see if an item has come every 15 min. If it didn't spawn there it gets dragged there. You may see 2 items have come in the last 15 min. You ride to the first. cast invis on yourself. [Break spawn line if sight] Steal the first item. Cast invis on yourself again. [stealing and hide are both skills] get off the mount, (anything from the charger to fallen to the rideable polor bear.) stalth back to the other and steal it. Then back onto the mount and run to the next area.
Another would be stealing say next to a balron. You never wait till it walks away. You run up and cast invis, steal, then run again or cast invis again. The trouble starts when you fail a steal. If the place has an Oni and fan dancers. One of them may see you when you try again. Or if it is one of the paintings that are a double. Miss it more than once it can be best to stealth away.
If your intent is to steal from a player. Not haveing stealth and snoop is not an option.
That one you noted is fine for a Doom thief.
With only 120 stealing, 100 magery, 100 hiding alone you can start stealing in doom.
