Re: Monster Survive
For the monkey: Make sure there are only two spots you can travel to on the map (the one with the beetle and the monkey). Search around the areas until you've gotten every event, which, since I can't read moonspeak, just seems to be them talking to each other.
It's actually a pretty easy fight when you get used to his pattern; when the monkey disappears, he's preparing to a special attack; if you defend, no damage is dealt. Just keep attacking him and healing when necessary. As long as you defend during his special attack, he deals no EP damage. There's a second fight with him, back-to-back, but you're characters are completely healed. He even seems weaker the second time around.
