Buffer against multi-hit attacks
Lucky Tonic grants one Buffer. Against a multi-hit attack, that charge prevents one hit that would lose HP, not every hit in the displayed total. A sequence can remain lethal after the first hit is prevented.
The charge can also be spent before the enemy attacks. Damaging statuses and cards that make you lose HP can consume the protection on a smaller event than the one you intended to stop. Read the whole turn rather than inspecting only the enemy’s final attack.
Compare it with Block Potion using the actual sequence. A single large hit favors one-event protection; several smaller hits can make ordinary Block more useful. Neither potion restores HP, and neither should be counted as a revival.
Before ending the turn, identify the first event that reaches HP and calculate what remains after that event is prevented. If the later damage still kills you, another card, potion or kill must change the sequence. The Lucky Tonic guide gives an explicit multi-hit example and explains why self-inflicted damage can spend the charge first.
