Not sure if this is an ACTUAL bug, or if is working as intended. But Spotters Call/Coda of Jeopardy does far more damage than Oracles Corroded Defense and Archons Illuminate, or even Druids Thorns of Ire.

It seems to me that the Spotters Call/Coda of Jeopardy are doing the damage shown on the tooltips, but none of the others are.
