Assassin/Ninja Max Level Assassin Build

I'm looking for a max level assassin build to work towards once I get there. No mythics/crafted please and I'd prefer spell spam unless melee is objectively better (idk which is better). Another thing that I'd love if possible is if I could have a relatively high walk speed because I hate being slow (current walk speed is +106% but I understand if that's a bit much).

Current build:
Anamnesis
Booster Plate
Dark Shroud
Steamjet Walkers
Black Catalyst
Black Catalyst
Double Vision
Ensa's Faith
The Visionary's Vice (t4w,t4w)

 

that is supposed to be two tier 4 water powders on the weapon, idk what that's supposed to look like

 

Spell Spam:
https://wynnbuilder.github.io/#4_07R0RZ0u50I609q09q0OJ0og05n000t1h1u001g00001006CC
WynnBuilder build:
> Cancer֎
> Medeis
> Adrenaline
> Frenzied Mockery
> Black Catalyst
> Black Catalyst
> Diamond Hydro Bracelet
> Tenuto
> Black [t6f6f6]

Heavy Melee:
https://wynnbuilder.github.io/#4_0K30oY0CE0640I90I902d09t0211p11-Q0y+t1g00001001Z6
WynnBuilder build:
> Obsidian-Framed Helmet
> Taurus
> Writhing Growth
> Blind Thrust
> Fractured
> Fractured
> Atlas
> Drain
> Anvil Crawler [e6e6e6]

 

people mostly go letter for element then tier of powder in square brackets like kioph used.
So two tier 4 water would be: [w4w4]
elements are: e, t, w, f, a (earth, thunder, water, fire, air)

this is because WynnBuilder, the currently most used site for builds, uses that format.

 

ahhhh ok thanks for letting me know!

For the spell spam build, since I have negative mana regen, do I need to carry a second weapon so I can use vanish to run around while not hitting mobs? Also I still don’t exactly understand mana steal. Does it work once every 4 seconds or give you x mana over 4 seconds or what?

 

Mana steal is quite... unintuitive. But it basically goes as follows:
there's a certain chance it'll trigger with every melee hit. The chance differs based on the attack speed you use.

If you are hitting an enemy non-stop as fast as theoretically possible, you should get one proc of mana steal about every 3 seconds.
People generally prefer super slow attack speed with mana steal because the chance per hit is much higher and it's easier to land each hit at the right time, making it more consistent for regaining mana.

Also, as a side note, it counts for each mob you hit. So if you hit two mobs at once, you can get more mana.

Here's a thread with the found percentages:

wynncraft is broken: mana regen - YouTube
^ little video on how mana regen is also not what it says.
But for you, basically, you already naturally regenerate one mana every second. -1 mana regen every 5 seconds basically still makes that +4 mana every 5 seconds. So not a problem.

That build has plenty of mana to use.
