Any tips someone can give me for getting past king?
either do archery, or get a shield with haste and shield spirit using only 1 weapon, there really isn't much to get around spikes besides candle or a strait up haste shield, archangel armor and a haste shield could do it.
or you could get a regenerative whetstone with a shield spirit, and out regen his damage, cleansing potions also reset his spikes and rage so there is that option.
