Don’t get baited buying this item, while the stats are nice, in order to get an omnivamp you would have to be at least 5 seconds in the combat and by that time you would either get blown up or forced to disengage due to low health or the teamfight would be won.

Either they buff this item so we can proc omnivamp faster or give back omnivamp on passive just like now, or this item would be relatively weak, especially compared to all other upcoming mage items.
