Learning goals
- Understand invulnerability windows.
- Understand evasion as reduced chance or ability to be hit.
- Understand cleanse and reposition tools.
- Use Rolling Guard-type effects conceptually.
- Avoid wasting emergency windows.
Explanation
Some tools create brief windows where damage, status, or targeting pressure can be avoided. These can come from abilities, shield gates, Overguard depletion gates, Rolling Guard-type effects, Transference, mission mechanics, or special ability windows. Evasion reduces the chance or ability to be hit through movement, invisibility-like behavior, accuracy reduction, or enemy disruption. These tools are strongest when used to cleanse, reposition, restore shields or health, recast defenses, or wait out a cooldown.
Mechanic note
Do not treat evasion as full immunity unless the source specifically says so.
What should I do?
Use emergency tools when burst damage, dangerous status effects, knockdowns, recast timing, shield recovery, or repositioning are the immediate problem. During the window, move, cleanse, restore, recast, or kill the threat instead of waiting in place.
Common mistakes
Avoid these defensive mistakes before spending Forma, arcanes, expensive mod upgrades, or changing a whole build.
- Using invulnerability only after the danger has already passed.
- Forgetting cooldowns.
- Not repositioning during the window.
- Cleansing before the dangerous status is applied.
- Treating evasion as guaranteed immunity.
- Standing still after a Rolling Guard-type effect.
Key Takeaways
- Emergency tools are reset windows.
Practical task
Emergency tools are valuable only if you spend the window well.
- Pick one emergency tool you own.
- Trigger it in a safe mission.
- Use the window to reposition, restore a layer, or recast a defense.
- Watch the cooldown or condition.
- Write when you should use it and when you should wait.
You can use an emergency window to reset pressure instead of only surviving one hit.
