Theorycraft: Mighty Stealther Build
I run with a very similar 0/20/30/0/20 build with Prismatic Understanding (love it), but with different weapons. (staff + scepter/focus).
Thanks to around 50% crit chance and the Vigor proc on a crit, I have more than enough endurance for dodge/clone generation. I only use phase retreat and dodge to create my clones, that’s enough (I avoid creating scepter clones because the are worthless ones and overwriting my precious staff clones. Scepter in my build is just there for #3 attack to appyl 5 stacks of confusion.) Torch would be cool (for extra stealth) but I need the speed from focus (WvW player here).
Since I don’t use 1h sword I don’t have the trait Blade Training but instead I got Desperate Decoy. Together with Prismatic Understanding, the stealth effect from Desperate Decoy (when your health drops below 25%) is better and often saved my life in really desperate situations.^^
I’d say you don’t need Mirror Images, except maybe for double-shatters (but I doubt this is supposed to be a heavy shatter build). How about using Null Field instead (you have zero condition removal right now).
Why do you use the Mirror heal? You’ll have 3 illusions up at basically any time, Ether Feast heals for a lot with 3 illus (cooldown is a bit slower but not really a factor).
Interesting idea about the Altruism Runes. Haven’t tested/thought about this yet.
One thing to consider is that boon duration does not affect illusions. The buffs from your staff clones will still only have the base duration.
Have you considered Runes of Lyssa? The condition duration doesn’t transfer to clones either, but the 4pc and 6pc bonuses might compliment your build nicely.
I’m not actually using these runes right now, I’m just theorycrafting for a new build idea. I was originally thinking of using the Mirror Heal for the shorter cooldown to activate more might stacks. Against a ranged it could be timed right coming out of stealth.
My actual spec is actually using Runes of Lyssa right now, the number 6 has saved me quite a few times. My only beef with my build right now is the boon duration is so short, which is why I was thinking of this build idea.
