Primary Skills

 * Death Sentry: Due to Corpse Explosion's high damage and radius it makes this the most devastating skill in the Assassin's arsenal and can "clean" a room full of monsters in mere seconds therefore it should be maxed out.
 * Wake of Fire:

Secondary skills

 * Lightning Sentry: Death Sentry's synergy. However it only increases the Lightning damage dealt not the effects of Corpse Explosion so if the player prefers using fire traps instead then he can skip upgrading this skill.
 * Fire Blast: Synergy to Wake of Fire. Also increases Death Sentry's number of shots fired. (one shot every 3 levels)
 * Wake of Inferno: A flamethrower-like trap. Also Wake of Fire's synergy.
 * Burst of Speed: At first sight, this skill seems pointless for a Trapster, but it secretly increases your traps' firing rate making it much more useful than Fade for this build.
 * Weapon Block: One point should suffice, the + to Skill gear will do the rest.
 * Claw Mastery: Prerequisite for Weapon Block.
 * Charged Bolt Sentry: Prerequisite for Death Sentry.
 * Shock Web: Prerequisite for Death Sentry.

Optional Skills

 * Mind Blast: Temporarily stun a small group of monsters with a chance of turning them onto each other. Seems to work like Stun and Conversion combined. One point is enough the + to skill gear will do the rest.
 * Cloak of Shadows: Prerequisite for Mind Blast.
 * Psychic Hammer: Prerequisite for Mind Blast.

Hireling
The Act II Desert Mercenaries with Holy Freeze are the ideal choice for the Trap Assassin. Equipped with either for more damage (dealt from traps) or  if mana recovery is a priority.

Note: Holy Freeze can destroy corpses which prevent Death Sentry from using Corpse Explosion.
