We’ve taken a look at the interaction between the Jawas and Geonosians, and while the way thermal detonators are being applied is bugged (pun mildly intended), we think this is an interesting interaction and do not intend to take it away.
As such, we’re still working out the details, but we think we’re going to turn the bug into the intent and change the description to match. The ability moving forward will look something like the below (we’re still working on the final text and may change):
"At the end of each turn, Jawa Scavenger has a 50% chance to inflict a Thermal Detonator on all enemies that used an ability that turn for each time a Jawa ally was attacked that turn."
We’ll roll out the fix in an upcoming release and will notify you when that’s incoming.
