Suggested Killing Methods
Ranged/Magic
Giant Skeletons have no resistance to magic so it is recommended over using range however the time to kill between styles doesn't differ too much. Rocks are scattered across the Professors Dungeon area which can be used to safespot Giant Skeletons in order to avoid taking all damage.
Melee
It is highly recommended that the player uses the Soulsplit prayer if they are looking to fight Giant Skeletons with melee; this is because they hit through the protect from melee prayer. All three styles of melee can be used against them however they are weakest to crush weapons.
