Extended Spikes and Bed of Barbs is excellent for killing minions and doing AOE. The minions run in a straight line, so its very easy to line it up to hit every single on of them. Legion of Beetles and the AOE burns down minions. The Bed of Barbs and Extended Spikes works very well to stun and slow enemies. I go with Chitinous Plating because you can take more damage. Locust Swarm + Hive Master does VERY good damage around you to all enemies, it also heals you over time. The Vampire Locust is very good for finishing off enemies at range. I go with Blood for Blood because it does a lot of burst when combined with locust swarm and when enemies are stunned from Impale.

All around this build does very well at higher levels when in team fights. The self healing and shielding is very good to stay alive. The locust swarm destroys enemies in team fights.
