Big Mushroom

Big Mushroom

Event
Upon pickup, raise your Max HP by 20. At the start of each combat, draw 2 fewer cards.

Picking it raises Max HP by 20 immediately; the cost is that your turn-1 hand is 3 cards instead of 5, checked only on turn 1. Later turns draw normally. It is a one-time pickup relic, so it cannot be traded away. Your character also grows to 1.5 times size on screen, which is purely visual.
