Bleeding Berserkir Axes

The closer you are to death, the harder you are sure to hit.
Overview
Bleeding Berserkir axes are an enchanted version of the standard 
Their bonus damage increases by 0.2% for each point of missing health, not for each percent of health lost. In practice, the lower the player’s health bar is, the stronger the axes become. This makes them a high-risk weapon that rewards aggressive play and careful health management.
At quality 1, the weapon has 140 slash damage and 175 durability. Upgrading raises it to 145 slash / 225 durability at quality 2, 150 slash / 275 durability at quality 3, and 155 slash / 325 durability at quality 4.
- Quality 1 requires 1 Berserkir axes, 5
Flametal, and 1
Bloodstone.
- Quality 2 requires 5 Flametal and 1 Bloodstone.
- Quality 3 requires 10 Flametal and 2 Bloodstone.
- Quality 4 requires 15 Flametal and 3 Bloodstone.
Because the bonus depends on missing health, Bleeding Berserkir axes are strongest when the user is not at full health. That same mechanic also means they are less consistent than ordinary axes, and their performance drops sharply whenever the player heals.
