lol health? no. no no no. you stack ap and use the health for a bit of extra tankiness. items that are absolutely core: DFG (synthesizes well with your ult though the timing is tricky) spirit visage (obv for boosted regen) rabadons obviously, zonhyas for armor, then the last couple spots are arguable. a will is good for the regen, then a ryali for extra health and the slow helps you to land your ult imo

but realistically watching vids like that one are your best bet ^

if you need help with itemization you probably need to brush up on playstyle as well
