I reached 500M totals:

Total of 500011194 experience spent on character.

This was my primary goal in my reinc and it has been now reached. I still need to make about 10M exp to make sure I stay above 500M totals after reinc (once 78 days have been passed and instant reinc tax is below 2%).

Otherwise, I can now concentrate on Tohelo’s potion research.

Found anyweapon from floor

While doing some solo exp, I came across curious Excellent-quality weapon:

Furnace room.
This room is over half filled by a giant porcelain furnace up against the
north wall. The furnace is a great dome, with a gaping opening facing the
center of the room.  Through this opening you see masses of red glowing rocks
on a thin bed of lava. A single thick pipe rises straight up from the furnace,
through a large fan, to the ceiling. Several smaller fans are set up around
the room as well. This must be how the tower gets its heating and ventilation.
A thin flight of stairs leads upward. 
Obvious exit is: up.
Excellent-quality fire pick <red glow>
A steel short sword
a huge pile of mowgles coins
a pile of bronze coins
A drow soldier is guarding this room.
A tired-looking dwarf works at the furnace.
A tired-looking kobold works at the furnace.

The Excellent-quality fire pick pick there is “anyweapon” (available from Shinarae’s monsters):

You concentrate immensely and mumble 'mega visa huijari'
Excellent-quality fire pick vibrates slightly for a moment.
The following messages seem to vibrate from Excellent-quality fire pick:
It is called weapon and identified as 'anyweapon', 'pick' and 'fire pick'.
This weapon can be transformed at will to any material and any weapon type.
Merely use the syntax 'transform weapon into <material> <weapontype>. Be
warned that you must drop it first, lest you be suddenly injured when the
weapon twists around to its new shape.
E, C and D did the heroic deed to bring this piece of equipment before you and it has been in the game for 1y, 163d, 12min and 12s. It is almost weightless, tiny, in good condition, it's showing only minor signs of wear and made of fire.

It has some handy uses, like being an almost weightless fire pick (for mining purposes).

Finding out the owner of the weapon was surprisingly easy. I found out that E and D were online and partying, so I asked from E if he had dropped it:

You tell E (fighting) 'Hei, satuitko hukkaamaan anyweaponin?'
E tells you 'hmm'
E tells you 'juu'
...
The air before you begins to shimmer and a form starts to take shape.
When your eyes clear, E stands before you.                              
You give Excellent-quality fire pick <red glow> to E.
E gives you 200 mithril coins.
