Guild Wars 2

Could someone please clarify to me how the skills and traits are used? I understand that the first 5 weapon skills are set in stone ans you cannot change them unless you change weapons. Healing skill at slot 6 only has a few choices that are listed in the healing skills section in the hero panel.

But what about utility skills? As I understand, there are multiple different tiers of utility skills unlocked at different levels. But can put any utility skill from any unlock tier to slots 7, 8 and 9?

Same question applies to traits. For example can I use multiple adept level traits from the same attribute? Something like both “rifled barrels” and “hair trigger” simultaneously, they are both adept-level firearms traits.

Thanks in advance.

Yes :-)

Clarifying: It doesn’t matter what tier utilities you equip, but most of the time the higher tier ones are the best.. (although it depends a lot on the situational setup)
For the traits: You can of course put a master trait in a grandmaster slot. However, most GM traits are worth it, so you’d be missing out on some handy stuff.. So for your example: You can put the rifled barrels in the adept -tier and the hair trigger in the master tier..

Alright, thanks for the help! Much appreciated.

You can use traits from the same tier at the expense of using a higher tier slot in the Trait line. I.E the higher slots can use ANY trait in that line you have unlocked.
