Well i am working on my Ventus 100% so im trying to get all the commands. I need help melding this one cant seem to find it. Also does anyone know how o get the secret LoD board?

To get secret board you have to beat all other Mirage Arena boards and it should unlock.

As for Tornado there are various ways to make it, use any of these combinations in command fusion and it should be made:

Magnega + Aeroga

Quick Blitz + Aerora

Aero + Aerora

Aerora + Aerora

Quick Blitz + Aero

Thunder + Aero

Aero + Aero

i did aeroa aerora

the best way to make tornado by melding, is to do this

 

Combine

 

Aeroga (Level 4 Command) + Magnega (Level 4 Command)

 

since it has a 100% chance of being made.

Just to note, the only way to guarantee getting Tornado from Melding is using Magnega and Aeroga.

Here's the whole list.

Tornado Magnega Aeroga N .V. 100

Quick Blitz Aerora O .V. 10

Aero Aerora M .V. 10

Aerora Aerora N .V. 10

Quick Blitz Aero G .V. 5

Thunder Aero I .V. 5

Aero Aero E .V. 5
