Does anyone here fully understand how this works? If so, care to share/explain? I'd like to add more depth to the question but that is basically just it, lol .

well you use weapons to add to your stats and items to add slots and attributes... i think... i dont fully understand either

Don't really know what you meant by Weapon customisation because you can either upgrade your weapon in the shop by merging it with other weapons or items giving it new skills and increase skills points. Or are you talking about your character using different type of weapons instead of your normal starter weapon.. I haven't unlock the different type of weapons your character can use yet.

As I understand it, each weapon has some base stats that it increases, for instance Attack and Spirit. Now, if you upgrade it using other weapons, then the attack and spirit stats can increase even higher, but it will never gain additional stats. So the trick seems to be finding a weapon that has good stats that you want, and then work on upgrading it. But it seems that you find better and better weapons as you advance in the game, so I doubt that the whole upgrade thing is terribly important until late in the game.

When you get a new weapon at the end of a stage it will be level 1 and have some stat bonuses attached. Weapons from earlier stages will only have 1 or 2 bonuses attached. Ones you get later in the game may have more to start with. The maximum number of stat bonuses a weapon can have is 6. A weapon can be upgraded by sythesising another weapon or item with it. The other weapon or item used is destroyed in the process, but points are added to the bonuses on the weapon you are upgrading. Every time you upgrade a weapon its level is increased by 1. Once a weapon reaches level 10 it cannot be upgraded any more. Synthesising weapons of higher levels adds more points by default and synthesising ones with more points in bonuses that match those in the target weapon also add more points than otherwise. Synthesising items with bonuses that match those of the weapon add points to those bonuses. Synthesising items that have special properties in boxes add empty bonus slots to the weapon. If a weapon has empty bonus slots, you can fill them by synthesising items that have the bonuses you want to add to the weapon.

Sorry, I was tired when asking this . I meant weapon synthesis! @spiritofcat: Thanks for the information! Really helpful .

I have been doing some research to try to figure out exactly how weapon uppgrading works numerically so I can plan how to efficiently create the best weapons. This is what I have uncovered so far: Level of weapon being synthesised has an effect on the increase of stats in the target weapon. Level 1 = +1 Level 2 = +2 Level 3 = +2 Level 4 = +3 Level 5 = +3 Level 6 = +4 Level 7 = +4 Level 8 = +5 Level 9 = +5 Level 10 = +6 Strength of matching stat bonus in weapon being synthesised adds extra on top of Weapon Level Effect. 19 = +1 (+3 from a level 3) 31 = +2 (+8 from a level 10) 34 = +3 (+9 from a level 10) 35 = +4 (+7 from a level 4) 35 = +3 (+6 from a level 4) Strange, these numbers aren't consistent. There must be another factor in action here. Maybe it has something to do with the target weapon's level or stat strength as well? Level 6 with Defence 47 gets +6 from a Level 9 with Defence 7 (Implies 7 = +1) Level 6 with Defence 47 gets +7 from a Level 10 with Defence 8 (Implies 8 = +1) Level 6 with Defence 47 gets +2 from a Level 1 with Defence 11 (Implies 11 = +1) Level 3 with Attack 19 gets +3 from a Level 2 with Attack 13 (Implies 13 = +1) Level 4 with Attack 35 gets +3 from a Level 2 with Attack 13 (Implies 13 = +1) Level 5 with Defence 40 gets +7 from a Level 10 with Defence 13 (Implies 13 = +1) Level 4 with Attack 35 gets +3 from a Level 3 with Attack 19 (Implies 19 = +1) Level 2 with Attack 13 gets +3 from a Level 3 with Attack 19 (Implies 19 = +1) Level 5 with Attack 42 gets +7 from a Level 10 with Attack 21 (Implies 21 = +1) Level 6 with Attack 49 gets +6 from a Level 9 with Attack 22 (Implies 22 = +1) Level 8 with Agility 24 gets +4 from a Level 4 with Agility 23 (Implies 23 = +1) Level 6 with Attack 49 gets +7 from a Level 10 with Attack 23 (Implies 23 = +1) Level 4 with Agility 23 gets +6 from a Level 8 with Agility 24 (Implies 24 = +1) Level 4 with Agility 23 gets +7 from a Level 10 with Agility 27 (Implies 27 = +1) Level 2 with Defence 23 gets +5 from a Level 6 with Defence 29 (Implies 29 = +1) Everything under 30 appears to be a consistent +1. Level 3 with Attack 19 gets +6 from a Level 4 with Attack 35 (Implies 35 = +3) Level 2 with Attack 13 gets +7 from a Level 4 with Attack 35 (Implies 35 = +4) Level 2 with Health 25 gets +8 from a Level 10 with Health 39 (Implies 39 = +2) Level 2 with Attack 13 gets +8 from a Level 5 with Attack 42 (Implies 42 = +5) Level 1 with Defence 11 gets +11 from a Level 6 with Defence 47 (Implies 47 = +7) Level 5 with Defence 3 gets +12 from a Level 6 with Defence 47 (Implies 47 = +8) Level 6 with Defence 4 gets +12 from a Level 6 with Defence 47 (Implies 47 = +8) Level 7 with Defence 5 gets +12 from a Level 6 with Defence 47 (Implies 47 = +8) Level 8 with Defence 6 gets +12 from a Level 6 with Defence 47 (Implies 47 = +8) Level 9 with Defence 7 gets +12 from a Level 6 with Defence 47 (Implies 47 = +8) Level 9 with Attack 22 gets +9 from a Level 6 with Attack 49 (Implies 49 = +5) Level 8 with Attack 21 gets +9 from a Level 6 with Attack 49 (Implies 49 = +5) Level 7 with Attack 20 gets +9 from a Level 6 with Attack 49 (Implies 49 = +5) Level 5 with Attack 17 gets +10 from a Level 6 with Attack 49 (Implies 49 = +6) Level 4 with Attack 16 gets +10 from a Level 6 with Attack 49 (Implies 49 = +6) Level 1 with Attack 12 gets +11 from a Level 6 with Attack 49 (Implies 49 = +7) Level 1 with Ride 12 gets +11 from a Level 7 with Ride 50 (Implies 50 = +7) Level 9 with Defence 28 gets +9 from a Level 7 with Defence 54 (Implies 54 = +5) Level 8 with Defence 27 gets +9 from a Level 7 with Defence 54 (Implies 54 = +5) Level 7 with Defence 26 gets +9 from a Level 7 with Defence 54 (Implies 54 = +5) Level 6 with Defence 24 gets +10 from a Level 7 with Defence 54 (Implies 54 = +6) Level 5 with Defence 22 gets +10 from a Level 7 with Defence 54 (Implies 54 = +6) Level 4 with Defence 21 gets +10 from a Level 7 with Defence 54 (Implies 54 = +6) Level 3 with Defence 20 gets +10 from a Level 7 with Defence 54 (Implies 54 = +6) Level 1 with Defence 17 gets +11 from a Level 7 with Defence 54 (Implies 54 = +7) Level 1 with Defence 15 gets +11 from a Level 7 with Defence 54 (Implies 54 = +7) Level 1 with Defence 11 gets +12 from a Level 7 with Defence 54 (Implies 54 = +8) Level 1 with Ride 14 gets +13 from a Level 8 with Ride 56 (Implies 56 = +8) Level 1 with Attack 11 gets +13 from a Level 6 with Attack 56 (Implies 56 = +9) Level 9 with Attack 9 gets +13 from a Level 6 with Attack 56 (Implies 56 = +9) Level 8 with Attack 8 gets +13 from a Level 6 with Attack 56 (Implies 56 = +9) Level 7 with Attack 7 gets +13 from a Level 6 with Attack 56 (Implies 56 = +9) Level 3 with Attack 3 gets +14 from a Level 6 with Attack 56 (Implies 56 = +10) Level 4 with Attack 4 gets +14 from a Level 6 with Attack 56 (Implies 56 = +10) Level 5 with Attack 5 gets +14 from a Level 6 with Attack 56 (Implies 56 = +10) Level 6 with Attack 6 gets +14 from a Level 6 with Attack 56 (Implies 56 = +10) Level 5 with Defence 20 gets +13 from a Level 8 with Defence 61 (Implies 61 = +8) Level 4 with Defence 19 gets +13 from a Level 8 with Defence 61 (Implies 61 = +8) Level 3 with Defence 18 gets +13 from a Level 8 with Defence 61 (Implies 61 = +8) Level 1 with Defence 15 gets +14 from a Level 8 with Defence 61 (Implies 61 = +9) Level 5 with Attack 5 gets +16 from a Level 8 with Attack 63 (Implies 63 = +11) Level 4 with Attack 4 gets +16 from a Level 8 with Attack 63 (Implies 63 = +11) Level 3 with Attack 3 gets +17 from a Level 8 with Attack 63 (Implies 63 = +12) Level 1 with Defence 16 gets +15 from a Level 9 with Defence 68 (Implies 68 = +10) Level 4 with Defence 4 gets +17 from a Level 9 with Defence 68 (Implies 68 = +12) Level 3 with Defence 3 gets +18 from a Level 9 with Defence 68 (Implies 68 = +13) Level 3 with Attack 20 gets +15 from a Level 9 with Attack 70 (Implies 63 = +10) Level 3 with Attack 19 gets +15 from a Level 9 with Attack 70 (Implies 63 = +10) Level 1 with Attack 11 gets +16 from a Level 9 with Attack 70 (Implies 63 = +11) Seems like the lower the stat in the target weapon, the more it gets increased by synthesising a weapon with a high matching stat. Synthesising an item will yeild a basic +1 to all stats just like synthesising a level 1 weapon, but matching stats give different increases from items than from weapons. 10 = +1 15 = +2 30 = +5 So to make a nice strong weapon it would be best to always synthesise level 10 weapons into it. Starting from a level 1 weapon you could do that 9 times. If the level 10 weapons you were feeding it didn't have any stats that matched the weapon being upgraded then you would still get +6 to all its stats each time, 9 times 6 is 54, so you would end up with +54 to all the stats it started with. I'll edit this post to fill in more as I discover it.

Does upgrading weapons change the appearance of the weapon? or change it into another weapon, or JUST add stats?

It just changes the stats. Each character has 4 basic weapon types. Normal, Speed, Power and 'the 4th weapon'. Upgrading a weapon leaves its appearance, name and type intact and only increases its level and its stat bonuses.

Among "normal" "speed" and "power", are they all supposed to be pretty equal, or is the power weapon generally the best? I honestly cant tell a difference in the attack speed with them.

I think there's meant to be a difference in attack speed, but I haven't noticed it either. I tend to use the power weapons because they have a visible numerical superiority.

hm so far i have used power and speed weapons dont know if am wrong but speed weapons tend to have more speed stats and a bit of more attack speed than the power weapons on the other hand the power weapons tend to havae more attack than the speed weapons p.s. as for range stat on a weapon that i use with 65 range on it and its pretty neat xD when you use a musou attack if you have a wide range well you can kill enemies that cover the whole screen.
