Overwatch Terminology – What Teleporter and Armor Pack Uptime Mean

When ever casters use the term +X/+X They are referring to the weapon upgrade first, then the armor upgrade next. In your example +1 zealots would be a regular zealot with +1 weapon upgrade with nothing else.

You'll often hear them say casters saying "They're going for a quick +1 timing attack" which means that the person researching the weapon upgrade is building an attack for when the weapon upgrade finishes, giving them a timing window/advantage over their opponent (assuming the opponent doesn't have any upgrades).

You may notice, from time to time, you or enemies will take a few steps back and not act for a few seconds: that's stagger. It's essentially a very short duration stun. Tower of Strength simply reduces the chance of getting staggered by 50%.

Stagger is not affected by Conditioning, which only affects the weight value of equipped heavy armor.
