Shroom Charm adds 1 シュルーム (Shroom) to every attack made by the equipped card. Shroom is a stacking poison that deals damage equal to its current value at the end of the affected unit's turn, then decreases by 1.

The charm's value scales dramatically with how many Shroom sources your deck has. A single Shroom 1 per attack is decent but not exceptional. Two or three Shroom sources applying to the same enemy per round compound quickly — the Shroom stack accelerates and the enemy begins taking escalating damage each turn without additional effort.

For Shroom-focused decks, this charm is A tier and one of the first additions you want. For decks without a Shroom plan, it is C tier at best.

Prioritize on Companions that attack every turn or two. Consistent application is what makes Shroom stacks grow. Multiple attacks per round from different Companions each contributing Shroom creates a rapidly escalating clock.

Barrage-equipped Companions spread Shroom to the whole front row per action, turning one Shroom Charm into a multi-target poison source.

• Lumin Ring: increase Shroom application from 1 to 2 per hit, doubling stack growth
• Pomegranate Charm (バラージ): spread Shroom to all front-row enemies simultaneously
• Truffle Charm (トリュフのお守り): apply 3 Shroom per action from one charm, combining with Shroom Charm for 4 total
• Snow stall: freeze enemies with Snow while Shroom stacks accumulate to lethal levels
