items: 10 potions, 10 mega potions, 10 blues mushroom, 10 herbs, 10 honey, farcaster, 20 whetstones, 5 cool drink, at least 5 bitter bugs, 5 ice crystal.
dangers: when he emerges from the ground, DO NOT GET HIT!
it will reduce your defense by half, making you die in 2 hits.
When he charges at you dodge it and run to cut the tail (has to be at 30% health to cut), when he raises up wait for him to drop and get 2 or 3 hits into his face (making him trip by hitting his claws is not too bad either), he has 2 attack when he stands up, one is just drop down and another one is him screaming, do not get close or the scream will reach you, he will also shoot fire from the ground, so make sure you guard (yes you can guard those fire things without guard +2), another opening is when he bites into the ground and pulls it up, thats when you hit his claws, another attack is his scream beam, if you don't have full health you will die, thats when you attack his claws as well, when he burrows down and you're in front of him he will hit you, so be careful.
