-Go to your Inventory and Upgrade your Weapon Rune to +1
-Open CE and select "main.exe" from the list of process.
-Set CE to scan for "Exact Value" and "Byte" then proceed to scan for the value "1"
-Go to GC and upgrade it then go to CE and scan for the next value which is "2"
-Repeat the process of scanning till you get the value for that rune (you should get the value by +4 if your rune didn't degrade).
-Select the address and change it depending on the situation (Safe limit is +40 or lower in GCPH), no need to freeze the value.
