Ok they are NOT hard to kill, they run low on energy after like 2 casts. So far anything with Necro in the build using blood magic can really screw them up since they dont have the energy to keep healing as fast as a monk..
So far the best build ive tried to kill W/Mo is E/N. E allows for massive damage output and energy storage. N allows for you to eat their health away fast while hitting them for about 100 damage as a fire elemental.
Me/n or N/Me is effective as well. Use N for health drains again. and Me has a wonderful spell called BACKFIRE when ever they cast they take a good amount of damage. just look at the Me skill tree its full of wonderful spells to kill casters.
Hope this helps with the OMGWTFBBQ they are overpowered. There are 3 classes that can be used to kill them and they are not hard at all to beat.
To beat them here are a list of combos
W/n W/me R/n R/me E/n E/me M/n M/me N/me N/w N/r N/e N/M Me/n Me/w ME/m ME/r ME/e
If im missing any sorry.
