Question for PvE Revenant/Herald
Of course you can use it. But you don’t absolutely have to use it on cooldown in order to do decent damage. I like to save it for a moment where it allows me to do some damage while avoiding getting hit by something nasty.
It’s a dps gain outside of shiro. You should be using it and axe 4 or sword 2 to run out the energy while in glint to turn off facets before swapping to shiro so you don’t have to use one with nature and lose out on 50% boons for awhile.
