For mission V- III, the tariff of 5000 gold is easily counteracted. I equip a Lv.100 rifle with homing ammo and greedy killer on it. When the mission begins, I quickly open up the chests. If there's nothing I want, I then quickly one shot maybe 4 or 5 enemies before quitting out. Doing so takes mere seconds, and usually nets me between 15 - 20,000 gold. Just rinse and repeat, and you'll also build up your gold, while still never actually costing you anything.
You are right about 5->3, this stage is very fast, but u'll always get a minus of 5k gold. But there is a way almost as fast as 5->3, but with 42k gold (greedy killer lvl6 [55k with lvl8]) and 46k exp (soul eater lvl8) in every try. 1: Go to 8->6 2: Spawn Niel and hit it with an ice bottle. (Most people throw an electric bottle too but this will give u less then 20k in gold and exp) 3: Shoot a rocken on him (he dies instantly if u used an electric bottle) 4: Take a weapon too decrease the last few HP he has to a minimum. (I use a triple shot lvl100) 5: IMPORTANT: Make the final shot with a weapon what has BOTH, greedy and soul as high as possible. ( I use a lvl 95 Muramasa, but every other magnum should do the same good job) That kill gives with lvl 8 greedy and soul 55k gold and 46k exp, what results in a +of 50k gold per entry of the mission This takes about 5 sec of time and another 15sec to get all 4 chests. If the chest dont contain anything special just leave like in 5->3 and otherwise just do it. Hope this will help some people^^
Also if u get low ammo, you can enter the scenario and then get the ammo inside the boxes and get off the stage. The ammo will amount itself and you'll spend less coins.
