All support gems will be listed in order of importance. The main DPS comes from FIRST shocking mobs with lightning trap which prolifs, and then fire trapping them.

Main DPS = Fire trap --> Fire penetration - multiple trap - iron will
with 5 link add increased burning dmg with 6 link remove burning and add both conc effect and increased area of effect

2ndary = Lightning trap --> ele prolif - multiple traps - iron will

Single Target = bear trap --> added fire damage --> culling strike then whatever you want (like rarity or some shit)

Auras - Clarity around level 10, Grace, linked with reduced mana

Offskills - Enduring cry and Elemental Weakness are a MUST, you can also use decoy totem or rejuv totem situational

Optional DPS - since deerhunter boots are so good for this build I suggest butting EK in them (they become a trap) linked with --> added fire --> Culling Strike or Iron WIll --> blind

You're going for HP and mana regen mainly. you HAVE to have mad mana regen if you want max effectiveness.
Maxing resists are a must as always
Spell damage and Fire damage are the damage rolls you want.
Go for straight evasion pieces with 1 GOOD ES piece for that boost in mana from EB
