The tree spirit Arborick is a tough boss, but with this strategy you should be able to beat him.
You are stuck in the same mode you were for the Asassin and the Skurvywing, this means setting him on fire in a certain pattern. With your fireballs, hit his two hands, his two feet and his torso twice each. Fire the second shot straight after the first, while it's still red hot. Set him on fire quickly, or he will start spinning and regenerate his health; emitting flames. Watch the pattern of the flames to avoid them.
Watch out for Arborick's punches and kicks. His left arm (on your right) is his striking arm. Listen for a ; his arm will twitch, then he will launch it. Use Dragon Time to dodge it. One his first health bar is drained, you will move to higher ground and continue the fight. Now his punches are harder to avoid, but he no longer regenerates his health. He will still emit flames.
After two rounds of emitting flames, he will move right up onto where you are. Now just focus on attacking his feet. Use Dragon Time to dodge his strong attacks. Continue attacking untill his final health bar is down. You've beaten Aroborick!
Handy Tip: If you manage to die just as Arborick's first health bar is down, you'll move straight to the second round.........and your health will be refilled! It's hard to do, but worth the while!
When you are in the Ancient Grove, you will encounter some tiny creatures called Grove Mites.
These insects can latch on to Spyro and drain his health and magic! When one is chasing you, crush or burn it quickly. If it latches onto Spyro, the only way to get it off is with Fire Fury, which you may want to save for later. My advice is to avoid mites altogether.
Good luck defending!
To get the grove mites off you, you can also jump and press B while in the air.
in the part where u first see the floating jelly fish (wat the heck?!) you start off on a wood platform, if u breath fire on it for long enough it will colapse, you will fall and land on a small ledge. on the ledge is a tunnel, go through it and you will apear in a forest, in front of u should be a black dragon. if u beat it u will get a shadow element( it is hrd to beat.
In order to be able to do this, you first have to beat the story mode. When you have beaten story mode, go to the main menu and select extras. Load the save file with your completed game. Click on "dragon challenges" and beat all five of them. When you are successful the game will tell you that you have unlocked Dark Spyro. Go back to the main menu, load your game again and save it. Use the the element change button until you reach Dark Spyro (it's the last one in the elements sequence).
