These use quite a few abilities, they arent too bad as a melee physical option.
They use an attack combo which seems to do multiple hits.
These are mostly used for their debuff though.
Their debuff is called Thunder Web which has a 3 second duration and applies 15% reduced action speed and 15% increased damage taken.
The skill they use to inflict this debuff has a 6 second cooldown.
This does mean it has a bit of debuff downtime.
They do however use the ability whenever they have it off-cooldown which does mean it is quite consistent.
The buff is not stackable.
These can be found in maps with Beyond.
