Did I hear Top Lane Lorelai? Allow me to enlighten you!
I play top lane Lorelai and this is my build which works really well… most of the time.
AC is the obvious first item. She really needs that CP and attack speed.
Believe it or not, Metal Jacket is a must as a 2nd item. Lorelai is very squishy and needs MJ to survive the brutal bot laners/junglers such as Kestrel, Kensei, etc.
Then afterwards move into a Clockwork or Dragons Eye(I like clockwork because of cooldown and despite her A being the only damageing ability if a new enemy walks right into the fish pool(happens quite often) you still get the 10% cooldown reduction perk which is nice. But DE will be the better option most of the time)
Afterwards I get War Threads or Clockwork(if I haven;t got it yet) and round of with a Capicitors plate and a Rook’s degree.
Lorelai has very High base Damage because of her pools extra CP and despite the fact of having only 2 or 3 CP items, she can output a respectable amount of damage(can reach 50 k with ONLY 2/3 Items)
