So, as I put some time into this game, i decided to put in this thread some strats and the route. Maybe somebody will read this; and if you have improvements, please write them down here.
I will start with the starting monsters. What monster you get is random. Or at least I believe that; maybe it has something to do with the name and in which order you talk to the npcs. There are six in total: Two good ones, two normal ones, two shit ones. The good ones are: The komodo, it has good HP and ATT, and synthesises into a green dragon, which is immune to all breaths (multiple bosses use breaths). The other good one is the bad egg. It knows sizz, which is op during early game fights and levels quickly. The decent ones are the platypunk and the ghost. The platypunk has multihit, which is good for metal slime farming, but the skillset is trash. The ghost hast decent stats and has helm splitter at only 14 SP. The bad ones are the capsicum and the bag o‘laughs. The capsicum is slightly better: it atleast has okayish attack and attack boost. But its hard to level and has a shit other skillset. Rabble rouser is too inconsistent. The bag o‘laughs is shit, almost a reset. Fairly bad stats and useless skillsets. Only saving grace is a underwhelming trait and relatively good synthesis, being of the material families.
