Parameter Boost based on HP

Parameter Boost based on HP is a passive effect that boosts a stat by a specified amount relative to the unit's HP remaining or lost. This effect can be stacked with itself.
==Examples of stacking==
*A unit under Scorching Halberd Lars and Infernal Pyre Rugahr's Leader Skill would have 20%~180% Atk buff relative to their HP remaining, with 180% at full HP.
