Engineer Master Minor Inventions Trait Automated Medical Response does not activate if: You go below 25% HP with your healing skill on cooldown, heal back up past 25%, and then go back below 25% before the internal cooldown (which, by the way, is not listed in the trait tooltip) has expired.
Replication steps (using AED for convenience):
- Get below 25% HP (as indicated by Low Health Response System’s regeneration application).
- Use AED when near death, healing for 50%+ upon the would-be finishing blow.
- Get below 25% HP again (as indicated by Low Health Response System’s regeneration application) before AMR cooldown expires (90 seconds?).
- Notice that AED isn’t off cooldown.
It has the same effect on every other healing skill available to the Engineer.
