Tainted Jonathan's Gimmick: "Endless Hunger"
Hunger Bar - A Bar will appear below Jonathan's Health, which is Jonathan's Hunger Bar, this is will slowly deplete over time, if it depletes fully, Jonathan takes 2 full hearts of damage (Bypasses any damage reducing items such as Wafer), then the bar refills. (If in a boss while the boss is present, the hunger bar will be slowed down to a quarter of its normal speed.)
No Hearts - Heart Pickups of any kind are completely absent from the game.
(Full Health Pills, and 2 of Hearts have a 60% of being rerolled into a random pill or card respectively.)
Beast / Vampire Mode - Pressing V will cause Jonathan to switch into his Vampire mode. While in this mode, Jonathan is unable to fire tear, but has a grab attack, and can grab enemies, bite and feed on their blood until the enemy. While feeding, this will slowly fill the hunger bar and Jonathan's Health. (This is the only that Jonathan can regain health.) Jonathan can still move while holding enemies, but his speed cut to a quarter of his base speed stats.
Pressing V will cancel grabbing and turn Jonathan into his human form.
Jonathan can also grab other players and drink their blood to regain hunger and health, but will only leave players on half a heart.
Jonathan cannot grab Both forms of The Lost or Ghost Tainted Jacob.
(If Jonathan gets hit by an enemy attack, Jonathan will let go of the enemies.
(Jonathan cannot grab the following enemies.)
