Guild Wars 2

Hello, does anyone know if Compounding Celerity (movement speed + 5% per active illusions) stack with swiftness? Also, does Persisting Images trait (+20% phantasm health) stack with signet of illusions?

These kind of things are pretty crucial for determining a build, yet I cannot find definite answers to this!

Typically movement increasments do not stack and the more powerful ones override the weaker ones. At least that’s the case on my ranger. Swiftness overrides the Signet (and Trait for pet 30% overrides swiftness). As for the health I can not say…

Generally movement boosts do not stack.

The phantasm/illusion hp boosts do stack though.
