The Sear damage does not deal lethal damage to large jungle monsters with buffs (i.e. Blue Sentinel and Red Brambleback). This is so that the burn does not accidentally steal a buff that's being donated.
Unique Passive - Sear: Damaging monsters burns them for 60 (+ 30% AP)(+ 5% bonus AD)(+ 2% bonus health) magic damage over 5 seconds. Omnivamp against monsters provided by this item is not reduced by area of effect damage.
Unique Passive - Auto Path: Triggering Auto Smite 5 times consumes this item, granting all of the item's effects permanently as well as increasing the threshold and damage to 900.
Unique Passive - Huntsman: Killing large monsters grants 60 bonus experience. The first large monster killed grants an additional 150 bonus experience, for a total of 210. If you are at least 2 levels below the average level of the game, large monster kills grant 50 bonus experience per level below the average level of all players in the game. If your gold from minions is greater than 40% your gold from monsters, a lane minion will grant 13 less gold and 50% reduced experience. This penalty is removed at 20 minutes.
Recoup: Regenerate up to 8 − 18 (based on level) mana per second when in the jungle or river, based on missing mana.
