Nice, plunder the bank twice, and you get max of 10k gold = best weapon. =)
It was originally for Chuunin and lower so the Academy Students could get a decent weapon and armor during their first days on Shinobi Legends. It could be like that, too.
Translation to admin-speech:
"You should get the best weapon+armour to level up faster when you're low. Later on it won't be that much of a problem, but you would boost them at early stages, makes it easier to level."
Comment:
"Sure, and it gets more boring to play as you have maxed out weapons as n00b in 2 game days and are kicking oro at day 4. Then people say 'whoa, not more, that's it?' and leave the game'
When I read an event/special/module whose only purpose is to buff guys up... I refuse to introduce it, like I am doing it now.
Also, all I see is you can hop in and get it, no real consequences for longer on.
I'd personally after 3 failed robberies would prohobit you any travel to any town other than your home town and also would deny you the right to use the bank. Also you would be able to buy no dwelling nowhere as your reputation as a robber & thief precedes you. Bank robbery is serious there. All countries have a bank, and it is neutral.
