Meta Zen Build Dk/Arc/Nb U46 - Drachenritter Baue PvE - ESO

Skill priority: Flail (if debuff is running out or has less than 10s left) > Merciless proc (Try to shoot it at 9 stack) > Trap (recast it at least 1s before it expires) > Stampede > Claw > FoO > Scholarship > Runeblade

Ideal is to use the tentacule at 3 crux as it's a much stronger gcd than runeblade and you have little to no benefits to sit at max stacks, but your magicka sustain doesnt allow it on dummy. 

You want to start using KB at around 35%, while making sure to have 3 crux to get a last Flail when dummy is at less than 20% HP. Stop shooting Merciless at around 13%. Keep all your dots up while executing, unless dummy is at 10% or less.
