An interesting start for my 3rd character.

I just started my 3rd character for the game with seed #119813713 and there was a treasure room key about 5 tiles from me, I picked it up then went searching for the treasure room. I found a locked door but the key did not work, so I kept looking thinking there was another treasure room and another key. I found the other treasure room and opened it up and now I have a difficult choice to make.
Its contents are as follows:

• A broadsword <19> (Can't really use right now, will likely find another by the time I can use it)
• A +1 haste charm (Meh.)
• A door key (Take it and find out what the other room holds? Risk finding crap?)
• Scale mail <12> (Looking pretty nice right now)
• A staff of healing [?/3] (Also looking nice, but I think armor is the better choice)

Edit: My character did not make it far, died on Depth 4 due to hallucinations. So many damn frogs and not even darts to kill them all at range.

An even more interesting start for my 4th character:

Dungeon seed #119815221 seems to also generate 2 treasure rooms on Depth 1, with just one key not inside of a room. This key however is across the Stygian depths with no secrets that I can find to get to it. Am I to assume that one of the potions is a potion of levitation? Time to start quaffing.

5th character:

A seed with 3 treasure rooms, one holding the key to another. And the first key is across the Stygian depths. Found a switch that made a bridge across it (after drinking some potions). This one seems to have a setup of having the 3rd treasure room inside of the 2nd and blocked by a wooden barricade, and the 2nd treasure room inside of the first.
