• Effect: +5 Health
• Category: Defense / HP Boost

Heart Charm permanently increases the equipped unit's HP by 5 with no conditions or drawbacks. Simple, reliable, and universally applicable. It is the most straightforward defensive charm in the game.

+5 HP is excellent passive durability. On most units, 5 HP represents 1-3 extra hits worth of survival depending on enemy damage values. In a game where being killed means the unit is gone, even a few extra survival points can completely change the outcome of a battle.

The permanent nature distinguishes Heart Charm from Shell-granting charms. Acorn Charm gives 8 Shell that depletes — Heart Charm gives 5 HP that stays for every battle in the run. The cumulative value of +5 HP across 20 battles is much higher than 8 temporary Shell.

On your leader specifically, Heart Charm is particularly strong. The leader is the most critical unit — their death ends the run. +5 HP on the leader means more buffer against unexpected burst damage and a longer survival window overall.

Heart Charm stacks with other HP boosts and is enhanced by healing effects — having more HP means healing effects have more room to operate.

Equip on your leader for maximum run-wide impact. Your most important unit with the highest threat level from enemy attacks is the ideal target. Secondary choice is any fragile unit that keeps dying before dealing its full contribution.

Heart Charm is never the wrong choice on units that need to survive more than they need to damage.

• Cloudberry Charm: Higher HP ceiling means more room for kill-based healing to accumulate
• Hog Charm: Stacking HP boosts creates a very durable tank
• Acorn Charm: HP + Shell for layered defense — HP sustains after Shell depletes
