[Bug exist in Exodia Force?]

Exodia Force, as it's discription, it could have 20% probability to deal 150% damage of my weapon when I successfully deal a status.  

However, I could only saw a very tiny damage when the effect of Exodia Force appeard which never reach to 150% damage even lower than my weapon's basic damage. The enemy I use to test with no armor or aura of damage decrease.

I have thought it won't be influenced by mods so I taken them down and tried again. Only I could get was the same result -- even lower than my weapon's basic damage.

I'm wondering if there is any bug in Exodia Force or has a wrong discription to this arcane.
