This row is the most actionable thing on the page: unlike a ranking, it names things to go and buy. It is also pictures with no legend, so here is one of each.
14/hDoes not drop food — bring 14 Brown Mushrooms per hour of hunt
The protective imbuement for the element that most threatens you here. The row wears a shield rather than a damage-type icon because the shield is the actionable half — knowing to buy Lich Shroud beats knowing the hunt is mostly death damage. A grey shield means physical, where there is nothing to buy.
A trinket, for the same element — or for life drain, which no imbuement answers.
Effect badges: drunk, paralyse, mana drain, life drain. The two drains are badges rather than damage rows for the same reason: no imbuement answers them.
No food here. The number is how many you need an hour, so you pack before the trip rather than find out during it.

How the protection element is chosen
It is not the biggest single number. It is which element actually threatens you across the hunt, weighted by the mixture you fight — one creature with a spectacular fire attack that you meet twice an hour loses to steady ice damage from the four hundred you kill.
Which is why the advice for a hunt can differ from the advice for the scariest creature in it. If a particular creature is what keeps killing you, look at it on its own.
Why a life-draining hunt offers two trinkets
Only one trinket fits the slot, so this looks like a question the site should answer. Bone Fiddle answers life drain, the one damage type no imbuement can touch — but nothing in the data says whether the drain you face outweighs the element you would otherwise protect against.
Over half the hunts here drain life, so picking for you would put the same recommendation on most of the site while hiding the trade behind it. Both are shown with what each is worth, and the call is yours.
