This is my thought summed up (the minor details are not to significant). Presently just a select few familiars are ever used, and barely any do even marginally decent assault (especially in reboot). Thank you for Maple M Mesos!
To make things more interesting I was thinking a familiars ability should be randomized, with greater grade fams getting higher tier abilities at random. That way a recognizable that might not have been really good can prove to be good. This would also create more diversity in what familiars are being used.
But I believe a randomized potential-like system would be beneficial. Bad familiars might get good, useful abilities. Though the exact same logic can be implemented backwards, identification rather think about the positive effects it could have. Naturally people would want higher tier familiars, which are much more likely to have higher grade abilities. The randomized abilities would diversify use so everyone isnt working with the specific same thing (arachnaphobia anyone?) .
Keep in mind this dosnt randomize their enthusiast. Big Spider nevertheless gives 80% fall, Eye Of Time nevertheless gives x2 Maplestory M Mesos, so on etc. Just their abilities would be random.
Quests give Mastery Books too late
There are lots of quest lines from the game that award Guide For Maplestory mobile mesos Books (20, 30, or even both). The issue is that nearly all of them do it at a rather high level. However, the Tynerum quest line that begins at 135 and provides 2 degree 20 and two level 30 books is also very likely to be too late, along with the silent crusade awarding a degree 20 book at the end of chapter 3, at par 135, as well.
