Kukulkan Build Joust

Kukulkan is a god that is dependant on how much mana he has. Kukulkan's passive makes 5% of his total mana, into additional power. Now you don't want to overdue the amount of mana that you gain, you need health and lifesteal as well which is why you aquire warlocks sash and book of the dead. Warlocks sash gives Kuk the ability to have more health and mana instantly while also giving you stacks for extra power and health. The reason that you do soul reaver before tahuti is because it adds extra mana as power, general power and a 10% extra hit so when you land your ult, it KO's the first person in it's path. Add tahuti afterwards, and your ult is taking away 85% of most god's health.
