You can only use this skill once per fight, and Blind is still a gamble despite all. So here's an idea to make this 'once-a-fight' skill feel more impactful for its limited usage:

Pocket Sand

Reach into your pocket, grab a fist full of sand, and throw it in the eyes (or whatever seems the most like them) of 1 enemy within 2 Range, inflicting Blind for 3 rounds, and Disoriented LV3 for 5 rounds.

Afterwards, your pocket will be empty of sand, meaning you can only use this skill once per battle. 

Trickery: Automatically apply your Steal skill to the target.

Disoriented - Your senses are completely impaired, reducing your Hit to 0, and evade-ignoring effects are changed to Great Accuracy. Every time you perform any action with 2M+ cost, LV is reduced by 1. At LV0, the status ends.

No... I'd much sooner prefer it becoming a standard cooldown rather than once per fight over giving it more busted effects. Blind + Steal + Attack is a good enough combo thanks to Trickery as is.

On that matter, maybe it could work on a five round cooldown that gets reduced by 1 every time you take earth damage or get knocked down?

Kunai spitting. The knocked down 5 cd thing is cool

5 round CD, -1 Rounds per pocketed enchant you currently have.

[K Peculier]

-2 Rounds if enchanted with gravedigger. Embrace dirt.

5 round CD, -1 Rounds per pocketed enchant you currently have.

Pocket sand is actually a really strong, underutilized skill. This is because steal is a really strong, underutilized skill. Pocket sand being able to blind, steal from a range, and attack, makes it a powerful tool.

I think putting a big CD on it would be fine, I don't really see this as needing much of a buff

[Snake]

that's a lot of pockets for sand
