This build will allow you to take all the opponents lunch money by harassing them with auto attacks. The mana potions will help with sustain as well as the health potions. You can rush tiamat faster and improve wave clear. Depending on the build you are going you will still be able to have an impact as long as you didn't lose the laning phase too hard. Your pillars make a great cc to get closer to your enemy to chomp them down. In the start try not to use too much of your w and e as this will drain your mana a lot causing you to back. Focus on csing with q to reset and try to q your opponents if they go in for a trade as it does a lot of damage early. As soon as you hit 6 you can try and fight. Make sure to w and then ult to maximize your healing as your w gives 25% increase healing from all sources. Hopefully this helps. Thank you for reading!
