Does this benefit from the Hellcat Waistguard buff, and the +grenade damage buff?
Yes, but only when you cast the Cluster Arrow. Cluster arrows procced from M4 don’t get the effect from the Hellcat belt.
Cluster Arrow:Loaded for Bear grenades get the effect of the Grenadier passive, but not bonus Grenades damage on gear, as that is specific to the Grenades skill.
Thanks for your help. DDDDDDDDDDDDDDDDDDDDDDD
Just in case you’re a little bit disappointed about the damage output: The grenades from LfB deal only 250% weapon damage, not 850%. This is only the damage from the initial explosion, and it is not a “grenade” and does not “bounce”.
If you want to go full damage with CA and Hellcat, you should try the rune “Cluster Bombs”.
Well, I just tried with the belt and without, and with it the grenades do bounce, and without it they don’t. I don’t know about the damage, but what Cavender said seems correct.
