How the heck to beat the next one.

I am level 17 with HP 1060. Machina Soldier is level 12 with HP 3048.
My punch happens in ratio 4 to 1, my critical hit ratio is maybe 10 or 15 to 1, with full limit my max damage is 150 ....

How to deal with him?

What really grinds my gears is that my punch happens only once in a while and all my mana just goes ...

do what i've been doing, i'm level 12 and fighting Machina Soldier, i have gotten him down to 880 HP

the trick is to exploit the village healer, you can heal yourself if you are in a battle, so get a lot of money and go into battle, when your HP is low go to the village and fill it back up, only problem is you can't buy anything during a battle and your HP doesn't go up with time so your only source of money/HP is what your start with and that made by posting

cheating maybe, but it works

I beat Machina Soldier at level 20.

You can heal while battling? Never knew that, I will give it a try

As for the posting thing - I am not really the spammer type and I don't much like postcount++ threads, it is not my thing.

That's only in a monster battle. I once tried to heal in a user battle and it did not work; correctly so!

Heal = loose money, so the best will raise a few levels before fighting Machina Soldier.
So that your character get a bit stronger and with more hp

You don't really gain that much HP when you level up. One monster's hit would make up for the difference in levels. You just have to be lucky and make critical hits.

True, there is not much HP gain but it improves the monster bashing ability.

you don't get much but you will have more hp, evasion, defense, etc... Altough it isn't like getting 1000 hp, the other stats will raise and make you harder to kill, if you know what i mean.
