Here is how the weapon tempering works:
1. The base weapon(first weapon selected) will keep it's rank and affinity. So a 4 circle Heaven weapon will also stay 4 circle and be Heaven type as long as it is the first weapon selected.
2. The base weapon has a chance when tempering for the base damage on the weapon to go up. Each rank has a damage range.
3. The attributes from the base weapon will always stay on the weapon. So if you have Cyclone, Jubilation and Induction, the weapon will be guaranteed to keep those 3 attributes.
4. A weapon can only have 6 different attributes on it. So if the base weapon has 4 different attributes and the second weapon has 3 different than the ones on the base, the new weapon will keep the original 4 and randomly take 2 of the 3 from the second.
5. Once a weapon is filled with 6 attributes, further tempering can be done to raise the level of the attributes on the base. So if you have Cyclone 5, Induction 8, Jubilation 1, Velocity 7, Slash 6 and Flash 5, you can keep tempering until you get those all to max level 10.
6. When tempering 2 weapons that have the same attribute, they will always combine level up to level 10. So a weapon with Cyclone 5 and the other with Cyclone 3 will give you Cyclone 8.
These are the main things to know about the tempering. The best way to make weapons is to wait until you have a base weapon with 1 or 2 attributes you want then add weapons with 1 or 2 other attributes you want until you can make it with 6 you want. Patience and finding a good base are the hardest parts.
