Guild Wars 2

for what i can use it im new and dont know anyone can help ? thx

I had to search wiki to find out what you were referring to.

This skill become available to you when you get downed (your health drops to zero in combat). You channel this skill and it will heal you slowly. If you manage to heal enough uninterrupted you rally (get up) from the downed state.

I think OP actually meant badges, but typo’d..

Badges are earned for killing enemies. You can use these to acquire weapons and armor. Speak to the Weaponsmith and Armorsmith NPC’s at the spawning area’s in WvW for the listings..
