When I made my Bane Executioner, I went with Black Scorpion to stick with the theme. I already had summon reinforcements, so I got the disruptor also. Wow, what can I say about the 3 together. The 2 spiderbots were crazy damage dealers, but 3 are crazy.
After I hit 50 and started playing with my set IO's I went RV to play around. I got attacked by a tanker, which I placated, got a Executioner's Strike on after BU, but couldn't really do much to him, nor him to me. Then I summoned my 3 spiderbots and with their debuffs and holds I smoked his bags. With the Wolf Spider Huntsman, it would cause a lot of redraw for you, but I love the pets!
