Predecessor Builds > Mourn > Mourn Support
Buy the upgraded potion w/ your first 350 gold, then buy brimstone, do not finishing building it into fireblossom until you have void conduit online. Brimstone does enough extra damage to help you take Fangtooth and hold waves while ADC out of lane. Void conduit will allow you and the ADC to sustain in lane as long as you want, combined w/ the mana regen from the potion and a T1 mana regen item (you will end up needing this for Elafrost) I do not have issues with running out of mana on Mourn. Once you have Void conduit and Elafrost finished, finish building Fireblossom. I like going into radiant raiment next as i think it makes Mourn extremely difficult to kill combined w/ Leafsong, you can escape fights and heal up quickly, allowing for re-engages. I finish with Everblossom for heal bonus and damage mitigation and Unbroken Will for tenacity and armor bonuses. Mourn is a beast.
