Soldier

Background
If you think that the last 2 tiers are too easy for you, try this. You have 4 collections to collect.

Soldier covers levels 9-12.

Job Tier Mastery
Upon mastering Soldier tier 3 times, you will reward you with a Golden Skull which shortens your health regeneration time by 30 seconds.

Collections
Find all 7 items in the Sculptures Collection to gain 3 Defense

Find all 7 items in the Poker Chips Collection to gain 2 Attack

Find all 7 items in the Club Flush Collection to gain 3 Attack

Find all 7 items in the Boxing Collection to gain 3 Attack

Boss Fight
Dont forget to try your strength on the 3rd NPC boss, Luis Castana. You require 8 mafia and some energy in order to fight him. You will be given a Pair of Broken Glasses when you beat him.

How to Read the Tables
It's very simple. The first 3 rows are things you receive from the job (Payout, Experience,Chance to Loot), the next 3 are things you must have in order to do the job (Energy and Items), and the last 3 simply list how much percentage towards mastery you gain.

This is the best job in this tier for both experience and cash, giving ~1.56 experience and $3,450 - $5,175 cash per energy.
