After a couple frustrating attempts in the train Maple M Mesos and beating Shao, I have come up with a way to kill her to get Zero that should lead to no passing (it did for me personally, twice in a row,) plus a few(somewhat obvious, but still potentially helpful)tips for penalizing the train. The majority of the depends on the ability “Time Holding” so in case you’re too low to have this ability, this may not be as useful, but you still might find a couple hints.
Always head to the left as that’s where the final car is and the explosions you need to escape from beginning on the right side. Stay on the top for so much as you can as there is less things to block you and allow the explosions to grab up to you.When you do need to head down, simply jump near the border of the top of a car and you should get inside the next one.Don’t kill some of these critters, just press your potions and walk past them.Make sure you’ve got your “Rewind” on in the event that you’re large enough to have it. Should you make a mistake and the explosions have been in view, use “Time Holding” and try and get as far ahead of them as possible.
(She can teleport before you, occasionally, so if you have “Rewind” I do recommend having it on, just in case.) If she teleports, instantly press double up-arrow onto among those (apparent, no enemies on it) preceding platforms. Wait until you hear four (4) explosions. That is when you know there’s no longer any leaf bugs down under. (The foliage bugs will kill you within one hit.) Jump down and keep attacking. Repeat this till she starts spawning her giant fire spell.
When she starts spawning her buy Maplestory 2 Mesos giant flame charm, immediately press “Time Holding” and press double up-arrow to get on top of one of the high platforms, like before. Wait there until it finishes, and leap back down. I hope this can be helpful to anybody stuck on Shao. I could not find any other guides on this.
