When will tectonic armour get a passive

The short answer is, yes.

The longer answer is, yes but it's not something we have the time or the capacity to look at right now. As a combat team we are focused on the 'Sanctum of Rebirth' and have a number of projects lined up after. We have discussed how we would like to address smaller QoL combat changes and/or small updates to areas of concern, while fitting it around our active project work. However we are not quite there yet.
