ok how long will it take if i keep building book cases and destroying them and building again (repeat over and over) from 1 con to get 50 con? plzz help also how much will it cost?

You could do:

 

 

 

Wooden Bookcases until level 29.

 

 

 

At level 29 do Oak Bookcases until you hit 33.

 

 

 

At level 33 do Oak Larder until level 74.

 

 

 

At level 74 do Oak Dungeon Doors until level 99.

 

 

 

That's pretty much the layout for 99 con lol. Even though you asked up to 50.. :oops:

ok what should i bring and how much will it cost to go up to do reg bookcases to lvl 50

You could do regular bookcases all the way to level 50, but if you want to keep it as cheap as possible, you should do what ultimatballr says. I don't know what it costs, but for regular bookcases you need to bring a saw, a hammer, enough nails and fill the rest of your inventory with normal planks. You could use some kind of butler to speed things up a little bit.
