Cast When Damage Taken doesn't work

Dears devs,

It looks like the CWDT doesn't work properly.

After trying to make my stone golem linked with it appearing, nothing happen.

I already check, the stone golem has the good level with the cwdt.

I let monsters hit me and took more than 2K damage but cwdt didn't proc.

Normally it should have proc after taken 661 damage.

Can you have a look onto this?

I'm a dumb... sorry i didn't check that i didn't had enough mana to trigger the spell
