Wave of Conviction: Can't inflict Fire Exposure

The highest damage type I deal with Wave of Conviction is fire, and I also use fire penetration support.

The monster's description correctly shows the Scorch-icon and percentage for Legacy of Fury, and on rare occasions Lightning Exposure, but never Fire Exposure. Wave of Conviction does deal damage, monsters burn, but I never see the Fire Exposure icon.

I consistently watched this behaviour for a whole day. I tested it with Righteous Fire, Flammability Aura and Legacy of Fury equipped or not equipped, and on another class in standard - the result always was the same.

I didn't allocate Elemental Equilibrium and as a Gladiator I got no other sources of Exposure.

Exposure does not display an icon underneath the monster's health bar. Only non-damaging ailments display these icons, and Exposure is not an ailment.

You're mistaking Shock for Lightning Exposure.

Thanks for the clarification.
