Human Brain

A human brain in a jar that grants +2 Intelligence. Intelligence scales mana, spell power, and a variety of ability interactions, so this is a clean pickup for Mage builds or any cat leaning into INT-based effects. One of the better flat INT bonuses available at uncommon rarity. Part of the Human Body set alongside Human Foot and Human Eye.

+2 INT from a trinket is comparable to Glasses (+2 INT, -1 HP) but without the HP cost. For spellcasting cats where every INT point increases mana efficiency or spell scaling, Human Brain is a straightforward upgrade. It also feeds into the Mark IV trinket's INT snowball, making it a strong early companion for that build.

Part of the Human Body set. In a full Human Body build, the Brain's INT contribution complements the Foot's Speed and Eye's CHA to cover the range of stats a versatile cat needs. Even as a standalone trinket, +2 INT with no downside beats Glasses on most builds unless you specifically need the INT+HP-loss trade for some other mechanic.
