Killed by a dar battlemage on level 19 with 13497 gold.
A tragic death. The battlemage outwitted me. Killed me with a flamebolt. The were three dars, one battlemage and two bladedancers in a room. I was at the end of a corridor next to some sulfur flame field and in no condition to fight noone. One blademaster had discord casted on him and I was expecting the battlemage to attack him. I stayed in full view of him (or her?) because I wanted to have all the intel. And then the mage fired his bolt, ignoring the discorded blademaster. Maybe the other blademaster blocked the mages line of fire? Maybe he was smart? All I know is that I would have paid dearly for either a scroll of teleportation or potion of healing. Or a staff of obstruction which I left before.
I made a few bad decisions at the vaults. One was choosing the key instead of a ring of stealth which I really needed on the lower levels. I suspected it to be a bad decision when I made it, but I still made it.
Otherwise, this was a fairly unusual dungeon. It may be just my bad memory, but I don't remember there ever being as many potions of strength in a dungeon. As a consequence of that, my gear was the best I ever used (all numbers are from the end): a +7 broadsword and +2 plate armour. My strength was 18, also the higest ever.
Another thing about the dungeon: MY GOD, that was wonderful!!
Definitely one of the best sceneries I have seen in Brogue. Or anywhere else, for that matter. Chambers, lakes, bogs, bridges... only a random dungeon generator can make that happen.
And one other thing: this is my personal best. Previous was with Brogue 1.5.1 when I was chased by some monsters on level 17 and made a mad dash to level 18 trying to run away from them. I made 5 steps and fell dead.
I'll try to upload the game recording somewhere and post a link to it here.
