as far as i know, there's no f2p way to either get or lose an amount of lunacy that isn't a multiple of 5... that means netzach is p2w
Back in the early days, PM did a test of the mailing function where they gave out 1 single lunacy. They gave out the other 99 not long after, but I bet Netzach here could have let the 99 lunacy expire as a joke.
