This guide assumes you are already familiar with the basic mechanics of Kerapac which can be seen here #kerapac-hm-basic.
It is recommended to have a Nodon Dragonkin slayer task 
as the helmet boost does work. You may also use the Premier Artefact 
to have a 10% chance to not decrease the slayer task count with each kill. Headhunter's thrill bracelets may be used as a switch in order to prolong slayer tasks. The Trophy-Taker's perk also does the same.
Both the Magic/Melee hybrid, and Range duo methods described in this channel are advanced, and cater to high end gear and skill levels.
Zamorak Staff 
can be used instead of Guthix Staff 
as you will not be having any hitchance issues during the fight and it lowers Kerapac's magic level and applies a 1-minute accuracy debuff making it less likely for him to hit you. It also does the same damage and has the same adrenaline cost along with a cheap cost to purchase.
