Just this is good enough for me for today.
There is now an option to need to have a ward slotted to upgrade. We added this from many player requests asking for such a system to prevent accidently losing reagents. This option can be turned off in the option menu.
There is a new option to try until succeed. This was another often asked for player request to eliminate clicking numerous times on lower chance upgrades. Once you click to start this, it cannot be cancelled due to how it fires off behind the scenes. This will stop when it upgrades, or if you run out of wards.
There is now a streak breaker on upgrades. Each item will have a streak breaker value assigned to it. When this number of attempts is hit, the next upgrade will be 100% chance of success.
