Is fusion necessary?

Title says it all

I still don't get what's the different between
A lvl 1 non-fused pet and a lvl 1 fused pet

Are fused pets confirmed to always be better than non-fused pet? If yes, in what way?

Also, can you please also tell me how to fuse pet "properly". Like how to fuse or just what to do in fusing pet in order to make a good pet

Thanks in advance

 

fusion is absolutely necessary.
with the new party system, pets in the 5th to 8th slot are weakened. this penalty is reduced by the number of fusions.

pet power, which represents weapon atk, has a 25% chance to increase by 1 on each levelup (as long as it is lower than the pet's current level).
fusion adds the power of both pets together, giving a massive boost.

potential defines stat growth on levelup, which is important since pets cannot use equipment.
fusion adds 10% of both pets' current stats to the potential of the new pet.

pets get 1 free stat point per level, which is only half of what players get.
a fused pet receives additional stat points equal to it's maximum level at lv1. (those are like the stat points we got from emblems)

so, a fused pet will have higher stats than a non-fused pet, even if it's level is lower.

to fuse "properly" you need to 2 pets with similar attributes, so that you can strenghten the stats you want and get your desired combination of weapon/type/nature.
the most important step is to level both pets, as the maximum level of the new pet is the average of the current levels of both pets.

to increase your pet's maximum level, you need to fuse it with a higher level pet.
this is most efficently done in small steps, since raising multiple mid level pets is faster than raising one high level pet.
(and you get bonus power and potential with every step)

 

Fusion is not necessary, similar to how +s weapons also aren't necessary. But you would totally do it to get better performance

 

Okay so it's just a preference. Follow up question:

I currently have a lvl 60/169 sorcerabit with bow/p.def/devoted property. And i also just bought another pet, it's currently lvl 1/24 lavarca with staff/p.def/justice property. My question is, if i were to max my lavarca then fuse my lavarca with my sorcerabit, would it be good? Or should i find another pet to fuse with?(since sorcerabit is not at max lvl)

 

Not really. You would lose a lot of level cap if you fused 169 to a 24... but you can always build up the level cap again with further fusions

 

6 of my pet is currently level 90, their cap is 170.
should i fusion now or wait until all my pet level 170?

 

if you fuse now, the level cap will become 90.
but if that is ok for you, go for it. multiple fusions will make the pet stronger.
even if you wait for 170, you have to fuse with 170+ or the level will go down.
fusing 90 with 90+ will also eventually go higher, and with more power and it's faster.
leveling becomes slower the higher the level.
you can use this calculator http://coryn.club/pet_fusion_optimizer.php to determine the most efficient process.

 

is it any benefit fusion higher lvl monster other than the lvl will be high?
like more bonus stats or more power than fusion early at 90
because i can take my time leveling all my monster to 170

 

If your pet cap is 90 (after fusion), it will have bonus +89 stats for you to allocate, but its growth stats at cap will only be 90% of its potential.

On the flip side, you 190 pet stats will be 190% of potential once it reaches cap.

So its up to you if you want to fuse now or not . If you fuse now, you can still build up the pet cap later, but it'll take some patience

 

sorry if i am still confused
leveling all my 6 pet to 170 and then fusion them or fusion them at middle level like 90, the bonus still the same in the end result (till reach cap 190) ?
because from what i see, it takes more fusion if we fusion multiple level 90 pet until it reaches its cap (190)
and it takes less fusion if we fusion multiple level 170 pet.

 

more fusions are better, but level cap is a problem.
the link i posted earlier calculates the optimal level difference for most efficient fusion to raise the level cap.
although this is mostly for raising a specific species of pet, that has a set level limit on capture.
if your pet already has a high cap, and you don't intend to fuse it to another appearance with a lower level, then there is no need to cut down the level cap by fusing early.

 

A high level is important for any pet whereas fusion is entirely dependent on your pet.
A good dps pets should have high power, which requires multiple fusions. You would need to plan out a series of fusions to maximize its power and level while minimizing the amount of leveling you need for each pet being fused (to save yourself some time).
Fusion can be nice for tank and support pets to boost their stats, but it is not necessary. A high level is far more important.
