Health Booster - How To Use
Recommended Against Strong Monsters
Simply staying inside the effect radius of the Health Booster heals HP over time. If going against a new or strong monster, fighting while passively recovering is a viable strategy.
Greatly Effective in multiplayer
The Health Booster not only heals the equipped hunter but also his teammates. To prevent fainting during critical moments, and for faster healing, usage of multiple Health Boosters at the same time is possible.
Be Almost Invincible with Rocksteady Mantle
The Rocksteady Mantle negates damages from light sources, roars, and tremors. When used in conjunction with Health Booster, this allows the hunter/s to continuously attack without having to worry about taking damage or getting interrupted.
