How To Quint
 

This is an estimate on cost to make staff +25 may be more or less depending on success.

50p-25 plat bar min. may require more..
10p-1 evaporator with 30/30
4bp your level
90 reign essences.. poor value
1 reign of violence essence
1 change essence type scroll 10p
7 platinum quint essences @ 25p ea. (optional)

Estimated Cost in worst case....250plat - not including costs of blueprints, essences and headache if it blows.

Put in lab, 1 plat bar, 1 bp, staff and reign of ? (low value) ex element knowledge...brew,
Evaporate 25 essences to quints by putting evaporator in with 1 reign.. make sure to only bring 1 evap at a time. Do this until 25 quints.
Put staff, bp and quint into lab and brew.. will auto take pbar out of inventory.
Do this until around +18 unless want to take risk of it not blowing and starting you over and try for +25. If not stop at 18 you can buy plat quints for 25plat each that will not blow.
After staff is +18 stop, put in change essence scroll along with reign of violence and your staff..may require bp also..
Use platinum quints to add remainder +7 to staff..
When durability reaches 1k purchase blacksmith oil to bring back up.

Do same to rest of gear... doesnt matter what type of essence.. can always change later for cheaper.
