Cast on critical discharge not working please help

I have 22% crit chance
a 5 link with cyclone, cast on critical hit, discharge, and increased critical damage linked together in that order
I went to the docks and spun around and cleared the whole zone with no discharge procs. Is my crit chance just low and im getting absurdly unlucky, or am i doing something wrong?

Which character? What's your 5th gem in the links? Do you have any charges?

Tell us how you generate your charges, pls.

This is the build http://cb.poedb.tw/us/passive-skill-tree/AAAAAgABA5YEswceDdEOSA-rEZYWvxo4JIsmlScvKPoqCyo4LOEt0jWSNj062DrhOyg8LUGHRXxHBklRSshN41VLWfNd8l-wYENh4mKsY0NsjG1sbj1uqm-ecFJwVnDVcql3B3vDgpuCx4LkgwmDX4PMhMWHE4nTiq-MNpARkBuQVZJ9lS6Xl5hvmK2aE5o7m7WcpJ2qnz6f36IAplesZqyqtDi1SLXytz65Pr6AvrzAZsM6xPbGrspK2HbYvdvU3CPhc-UZ5c_sOO988B_w1fJF8uHz6vcy-ej79f4K_o8=

There is nothing in the fifth link, and no no charges, unless im using enduring cry.

You can't cast discharge without charges, trigger gem or not.

were talking endurance/power charges rite?

Any charges (power, frenzy or endurance).

Discharge derives it's damage by the number of charges you have as shown on the skill tooltip. Without any charges you can't cast it.

Must have missed that, thanks for clarifying

It's written at the gem's description:

"

Discharge all the character’s charges to deal elemental damage to all nearby monsters.

Deals x–y base Lightning Damage per Power Charge
Deals x–y base Fire Damage per Endurance Charge
Deals x–y base Cold Damage per Frenzy Charge
