Check out the easier way to do this with Flame Traps: Forbidden Land: Flame Trap Method
Basically this is a boss spiking mission. The objective is to meet and greet a big mother snake boss after killing some of her children on the way, and torture her until she tells you to stop. It is much easier if you lure the boss away from the center.

A DEF debuffer would be great for this so if you're not CannonM or MusicM, take Attila or Ody at least and another damage dealing merc for faster runs.
And now for the tips:
- Stick to 1 path.
In this run I took the bottom road while clearing mobs coming from the top and right.
As soon as you reach an entrance to the center where the boss is at, clear any mobs around to make a nice peaceful space for you to lure the boss to. Once you take care of that, move towards the center and meet the M boss.
- Lure the boss towards you instead of charging it.
After greeting the M boss, she gives your whole party a nice big persistent -16464 DEF and -8200 ATK debuff. In return you need to spank her until she tells you to stop. But there are more of hers kids nearby so do not go to her, instead lure her with magic and ranged attacks if any.
Guide her to that nice peaceful space you've prepared earlier. She has no AOE so with none of her nasty snake children to disturb you, finishing the mission should be easy enough.
- Killing Tikdoshe Eggs lowers Boss' HP.
These are those little round mobs. Killing these actually damages the Boss so you can choose to go around and kill them, although that would mean having to deal with the other cannon mobs.
There are 4 eggs you can easily reach: 1 at the start, 1 a bit North from the start, 1 at the South entrance, and 1 a bit further left of the South entrance. Killing these 4 would be enough to significantly lower the Boss' HP.
