Hero Optimazation

Just trying to get the most out of my heroes, especially ideas for the last hero remaining. Below are the builds i'm currently using, and hoping for suggestions on the last one and tweaks to the already existing builds. Note that these have been made through watching how my Heroes act while in battle, and which skills / how they use each skill. I've been using these on my Monk, so healing isn't necessary...and from my experience with henching higher level areas more damage output from heroes / henchies helps considerably when they're being healed well. Thoughts, comments, and suggestions are appreciated, thankyou.

Minion Master - Master of Whispers (Preference Based on Looks)

Soul Reaping - 12 + 1
Death Magic - 12 + 1 + 2
Inspiration Magic - 6

1. Jagged Bones
2. Animate Bone Fiend
3. Animate Bone Horror
4. Blood of the Master
5. Taste of Pain
6. Signet of Lost Souls
7. Leech Signet
8. Resurrection Signet

Critical Interrupter - Zenmai

Critical Strikes - 12 + 1 + 2
Wilderness Survival - 4
Marksmanship - 10

1. Practiced Stance
2. Choking Gas
3. Disrupting Accuracy
4. Critical Eye
5. Disrupting Shot

Note - Attributes on Zenmai are not accurate as of now, she is not level 20, and I can't be bothered to look at how her attribute spread will be when level 20. This is to be updated when she hits lvl 20, assuming the thread is still relevant.
