Specialist is personally the better choice out of starters for Zeus. Bancroft's gives the same Survivability and power, better than stacking warlocks. Gem is redundant with chain lightning so go obsidian Shard to shred tanks.
The first five,no starter, give u true Damage on any but a tank with obsidian even at 325 protections it leaves about 100 left
Eventually Sell Boots and replace with spear of the magus for additional shred with either your ult or chain lightning.
