What the faster way too 50 con?

The two fastest (and most reasonable) ways to level construction are oak larders (lvl 33) and oak doors (lvl 74). With a demon butler, I average 100k - 150k xp per hour with larders and 150k - 200k xp per hour with doors.

and what are the cost?

And also, what the fastest way to 33?

It doesn't really matter what you do to get to 33, since it doesn't take very long no matter what you do. Just keep building the best thing you can (but try to only use planks, not other materials like cloth, as it will be faster if you don't).

 

 

 

My guess in terms of cost would be somewhere between 500k and 600k.

okay ty :)
