Since we already covered the easier enemies of the Misty Summit, its on to the main targets of the zone. The first one you run into will probably be Excavator Gianoo, a flying drill wielding gremlin who happens to be one of the hardest for me. He comes with many annoying adds but really only has one move that will put you in danger - a long drill charge which is surprisingly maneuverable. I'm assuming you know to keep away from his wild swinging at close range and triple stomp hop that many previous bosses have shown before. The hard part about his charge move is reading it because he has one that's much shorter. Either way you need to evade at the last second, or it will hurt. A lot.
Gianoo was troublesome for me because of this, until I found out that he simply cannot catch you if you run. Yup. Run circles around him and drink potions to full. That was my solo strategy anyway, because I'm one of those guys that carries 100+ healing potions at all times. :P Much further up the mountain you will encounter Crazy Masaka, a chainsaw wielding version of this guy - but he is much easier to read as he does an aerial backflip before charging. Just remember to dodge at the last minute and be patient as you whittle him away.
This is how close before you should dodge.
Of the wood men bosses, Venukan is probably the first you'll encounter and you'll recognize him from the bristling array of weapons he carries. His fighting style varies depending what he wields (eg. axes = gnoll) and is most dangerous when up close with his sword, but you can still multi-dodge-dance around him. For an easier time keep your distance and convince him to change to spear/bomb stance, which he will try hurl at you but are easily evaded. Stay at the same distance so that he doesn't feel inclined to switch to something else.
Foreman Markan is the next wood man boss you'll meet, and his fight is in an enclosed room (Twilight Desert reaper tomb) and all his moves are basically denial of space. He summons exploding poison shrooms (which will get in the way of your arrows), do an easy to evade double roll, glow green for a bit then shoot a trio of green spinners (harder to evade) but most dangerous of all - he will stomp after you which I'm pretty sure needs three+ dodges to evade. There's nowhere to go in this fight so you need to out DPS him in whatever space the shrooms don't occupy. Evade as best as you can. Steel Muspell is another angry stomper who fights in a small arena. He is a lot easier to read after he throws his hammer at you, but while he wields that massive tool you need to be on your toes to evade the purple seeky orbs he can shoot which is best evaded by going under it I think (towards him). For both these fights I recommend being ready to transform.
Lastly we have Quick-Hand Seira, a bomb throwing gremlin who can do some serious damage if all her grenades connect with you at short range. The solution for her is pretty cheesy for a Kai though. In the area is a ladder to a high perch. Despite having wings she can't actually fly or attack that high so once you get up there just snipe her at your leisure.
Better safe than sorry.
