well apparently its possible to get an unleash every time. most weapons have a base chance of 35% for an unleash, but by wearing lost of "increases criticals" equipment you can raise this number significantly, and it is even possible to get 100% good items for this are riot gloves and hyper boots, I have to work on an english papare so I'm going to test this tomorrow...

That sounds pretty sweet! Just imagine equipping all that stuff along with the sol blade. Megiddo! Megiddo! Mwahahaha!

yes it seems to work, i currently have an 87% chance of doing it and if i get a mythril helm forged, i will have 99% chance, and i think that lluck boosts your chance of unleash, so it should always unleash!!!
i think over about an hour of gameplay i only got three non megiddo attacks, and two of them were critical hits!!!!!!!!!!!!!!!!!!!
*reverts into a n00b*
OMFG megiddo r0x0rz!!11!!!!!1111

Gosh,

First of all, your luck means NOTHING when unleashing.

There are certain items that, when equipped, increase your percentage to unleash.

Most weapons have a default unleash of 35%. However, it's possible to get a 101% unleash.
