Havent tried this yet but it sounds like it could work really good. Not sure how well a hero could run this one, but it would be quite hard for a player to run it.
16 spawning power
12 death magic
Explosive Growth
Bone Minions
Death Nova
Jagged Bones
The Idea is to use Explosive Growth then create bone minions so you get 68 lightning dmg to 5 nearby targets TWICE. Then when they are about to die use Death Nova and Jagged Bones. Death Nova will hit everyone for 85 dmg and poison them, then Explosive Growth will trigger for another 68 dmg as another minion is instantly made. Add in all the dmg the minions will be doing and this build looks like a pretty powerful dps machine. Only problem is that it is very difficult to target minions so a hero would have to run it.
Anyone tried anything similar to this? Does it work?
EDIT: Possibly add:
Boon of Creation
Feast of Souls
Signet of Creation
Imagine 10 minions all with Death Nova and Jagged bones on, while you have Explosive Growth up. Then you use Feast of Souls. I cannot even imagine the amount of dmg this would cause. You should be able to easily 1 shot a whole group mobs, and maybe even a boss.
Insane Bombing Damage.

yeah it works, and has been posted a lot of time ago in the heroes section

yeah that's pretty much the principle of the Rt/N minion bomber.

Feast of Souls doesn't work on minions. 10 minions is impossible to maintain on Rt primary. Build while gimmick is basically sound but loses value quicker than N/x minion bomber as PvE level rises. Extensive reasoning can be provided. Been thinking of updating the sticky with comparison between Rt/N and N/x minion bomber.
