Mainly to level(Maplestory powerleveling) a final attack, but you do not max booster which he stated. You max out Hyper Body which is important. Spear Mastery at 19 is ok because it only gives you in accuracy which is not gonna kill you. The only thing that bothers us is leaving Pole Arm Mastery with 6. Since you will be using your spear in the third job, but seems a little low. We do not have any more problems with this interesting "1.5" build though.

Our Final Thoughts with the Spearman Build: Once again, we truly do not care the level for your Spearman. We merely wrote this Maplestory guide to you. We still highly recommend you go pure(spear), but if you go hyrbid you must at least do the follow:

1. Max out some kind of mastery first. Preverably pole arm for more stable damage as a Spearman and the other later.
2. Come really close to maxing out Hyper Body.
3. Have some sort of Booster in at least spear for help as a Dragon Knight(Maple Story Mesos).

We do not care if you choose the hyrbid 1.5, the pure or our half and half, but either way you still accomplish those 3 things.
