Heimerdonk jgl pretty sick
you absorb this jgler item 50mana regen per 5
this allow ingenious hunter and cosmic insight (without any mana regen runes) for the luden echo procs*200%
jgl item allow to upkeep 40item haste cosmic insight after that for the triple luden proc, every 3.6sec
and since Heimerdonk not realy needs to overdo his item haste in a Wardstone, as mundo/zac/teemo likes a wardstone
