Guild Wars 2

I have an 80 Engi and am working on a grenade build that is right for me. Here are my questions:

1. How does Inertial Converter work with Elixar R? I attempted to test this but the tooltip doesnt specify a cooldown and when I used it in the field it seems hit or miss.

2. Whats the best stat combo for a grenade build? Im not worried about being squishy, just curious about damage output and stacking vuln. I like the idea of a condi build but it seems unless I’m fighting a dungeon boss the mobs never last long enough to justify it. Any insight would be helpful.

3. So far my traits are 30/15/0/0/10. With the extra 15 I’m torn between Firearms and Tools.

4. And finally Im wondering what sigils I should be using, bloodlust percision type thing? Or something to help with condi duration and vuln stacking?

I’m aware this info is already covered on this forums somewhere but I wanted to create my own thread. Thanks in advance for any insight!

1. Works just fine. The wiki says its a 90s ICD. type /wiki in game and it will allow you to look things up

2. Berserker is rumored to be ideal.

3. Tools is ideal. There are very very many threads on grenad builds, just scroll through the first 2 pages of the forums.

4. Personally I like a combination of one of these three force+accuracy, force+bursting, accuracy+bursting.
