no such thing as minimum investment because if u do not buy the boost attack & defend scrolls , exp boosts from L2 Store (not lcoin store) you wont be able to do anything just getting rekt daily by everyone
I was also hoping that these things would be in lcoin store but they won't. Eventhough people who pay a lot would still have a huge advantage due to the possibility of buying these boosts not 5 but 10 times in total as it was with starter kits and etc. But i guess tomorow we are chasing all the people who can't afford to pay 200+ euro per month away from the server
