Guild Wars 2

Weakening Strikes – Cause weakness to enemies you critically hit. Weakened enemies deal less damage to you.

Damage reduced: 10%
Weakness (5s): -50% Endurance Regeneration, 50% Fumble (Unrestricted) E.g Glancing blows.

Weakness as a condition is meant to stack duration, but if you crit with this trait on and they already have weakness it does not apply the additional 5 seconds.

Please fix?

You sure it’s not stack capped when you landed the crit?

Weakness stacks duration, but only up to 5 stacks.

This is kind of confusing, because you would intuitively think that it just continues to add duration until it receives some max time limit, but it’s not the case.

Let’s look at some examples.

Let’s say multiple players apply 5 applications of weakness with the following durations

1. 5 seconds
2. 10 seconds
3. 5 seconds
4. 5 seconds
5. 10 seconds

All 5 stacks would apply and increase the total duration to 35 seconds. If a 6th player attempted to apply a 6th stack with a duration of 5 seconds, it would do nothing. One of the previous stacks would have to fall off internally before it was increased by the 6th stack.

Now an alternative scenario, 5 players all apply weakness with 2 seconds of duration. All 5 stacks would apply and the total duration would be 10 seconds. Now, a 6th player tries to apply a stack with 25 seconds of duration. Once again, nothing happens. The total duration remains at 10 seconds until one of the stacks drops off. Once that happens, the 6th stack can be applied and increase it by 25 seconds.

I haven’t checked to see if it’s actually bugged, but keep in mind the trait also has 10s cooldown
