You can use the circular and stretched hides to make spined armour.
Dagannoth will hit fairly hard with their ranged and melee attacks. Players under level 90 may find it difficult to train on the lower level Dagganoth due to the amount of the level 88s in the dungeon as well. They are excellent training for higher level players with good armour. Guthan's is ideal as you can just sit there for ages and have them continuously attacking you. Just leave the area and come back when they stop being aggressive. Cannons can also be used very well in here - many creatures in close proximity all aggressive to begin with makes for amazing training.
They hit fairly hard with ranged and melee attacks, so wear armour that has a high range defence and use a melee based attack against them.
A darkened horror from the ocean depths.
