Basic Magical attack

I would like to ask on scalling of magical basic attacks?
How does it works?

Does anyone know formula?
Is it scalling with level and increased magical damage?
can magical attacks crit? I suppose not...

The current formula is: 35 (+25% of your magical power)

So:
A Agni at level 1 with 0 magical power would do 35 per basic attack.
A Hel at level 10 with 200 magical power would do 85 per basic attack.
A He Bo at level 20 with 600 magical power would do 185 per basic attack.

However they are going to chance the magical basic attack scaling with the Ah Muzen Cab (Its more complex, but they scale better and more similar to physical basic attacks scaling)

he new formula is: Base damage (+Growth per level) (+20% of your magical power) Base damage = 34, Growth per level = 1.45

So
A Poseidon at level 1 with 0 magical power would do 35.45 per basic attack.
A Ao Kuang at level 10 with 200 magical power would do 88.5 per basic attack.
A Zhong Kui at level 20 with 600 magical power would do 183 per basic attack.

It is also not possible to crit with a magic basic attacks.

Well it's currently 35+25% of your magic power. If you have 0, you do 35 damage. If you have 100, it's (.25 x 100) = 25 + 35 = 60.
Magic damage attacks cannot crit, and it is not scaling with level.

HOWEVER
This is literally going to change THIS patch.
It's now going to have a base damage (similar to the 35 in the previous statement), plus a set amount per level (such as +2 damage per level, which would mean 40 at max level), + 20% o your magic power.

The template is 1.45 damage per level, base of 34, with 20% scaling, but I believe that's just for He Bo. I think it's on a case-by-case basis.
Otherwise, this isn't going to matter nearly at all. This is from the patch notes:

OLD - 35 (+25% of your magical power)
Example
- He Bo level 1 with 0 magical power = 35
- He Bo level 10 with 200 magical power = 85
- He Bo level 20 with 600 magical power = 185

NEW - Base damage (+Growth per level) (+20% of your magical power) Base damage = 34, Growth per level = 1.45
Example
- He Bo level 1 with 0 magical power = 35.45
- He Bo level 10 with 200 magical power = 88.5
- He Bo level 20 with 600 magical power = 183

******* IT NEX xD
so close

EDIT: to make it seem more friendly and not angry...

Thanks you very much but I am now little confused due to ...

Isis' basic attacks also deal 35 magical damage plus 25% of her magical power, and utilize a three swing chain, with the final hit having increased swing time and damage in a small AoE.

whats the point of this passive now ? :-) when it seems that everyone have same passive...

Its just that she was the first with magical damage basic attacks :P

Guessing they just haven't cleaned it up yet or something ;)

^ basically.
but the 3rd hit DOES hit in an aoe, so it's sort of still a thing.

thanks for help ... and maybe just one more thing ....

what about magical lifesteal? Does it works also with basic attacks? :-D

btw. I asked how this works because I used to stack very special build in past (Ymir with physical attack and critical, attack speed and damage can hit for incredible amount of damage)

But I log on after long time wants to fit it and then realize that I cant tak physical attack items at all...

I don't inherently remember, but I believe they do indeed give lifesteal, because it's mean to be equivilent to physical lifesteal.

And if you're doing that, I suggest the Warlock's Sash, Polynomicon, Etc combo.
