Desto Staff Healer - Warden Build PvE - ESO

I've used this build as a healer in Dungeons with PuG and other groups and in some trials. It also does solo content pretty well as it has two destruction staffs and although not a dps build does do reasonable damage.

You want to keep your Blue Betty up all the time and Lotus blossom if you can, I tend to pop them running between fights, then switch bars and drop Budding Seeds on the party as they run into the next fight, procing  Spell Power Cure to give them all Major Courage, and likely procing Chokethorn.
Then drop the unstable wall, to get some dps going and the critical ticks procing Hollowfang and switch to destructive reach spammable woven with light attacks.
If healthbars start dropping weave in a Living Trellis or two and then back round the rotation.

For bosses, I start with the same opening as above, after Budding Seeds stick the Elemental Susceptibility on the boss then bar switch to Crushing Shock spammable with Energy Orb and Enchanted Growth heals when needed.
