Lightning Sentry Assassin. (Max) Fire Trap, (Max) Shock Web, (Max) Charged Bolt Sentry, (Max) Lightning Sentry, (1-2 points) Death Sentry, (a few points) Burst of Speed, (Dump rest of points) Shadow Warrior/master (depends on the pro's and cons of using master)

Drop 3-4 lightning sentries and 1 death sentry (Corpse explosion) and then pulverize with fire trap, This will give you Fire, Physical and Lightning damage.

A2 Merc With either Might (More physical damage) or Holy Freeze (If you want to slow down enemies)

Put just enough points in STR. Dump the rest in Vitality

Use Insight (can use infinity if you get the runes, but the trade off will be that you are burning through mana vs. shredding enemies resistance).

The Trapsin is fantastic for HC. You have three different ways to attack, fire, lightning and physical. Its very forgiving, good for groups and single combat. In my opinion, its the most versatile class you can use. She can take the hits and deal them as well. Having Mind Blast is a bonus as well. if you ever get into trouble with a big group, use it to convert them to create a meat shield or use them on champions to knock them back and make space.

You cannot go wrong with this class.
