I've been testing a grenade build with the titan behemoth for the past couple months, but wasn't until recently that I was able to confirm my suspicions about a possible bug with the darkness classes. See, Today a mod was sold by Ada-1 called "Heal Thyself," which states that any kill with a grenade replenishes health. However, whenever I shot or slid through my ice glacier grenade, wither the enemy be frozen or not, the grenade kill almost never registered as a "grenade kill" specifically. Yes, I would get the affect on occasion, but also note that I've had Whisper of Fissures equipped through all this testing, So the theory that I might just be missing enemies in the ice explosions, especially at point blank and frozen, is very unlikely, as the increased blast radius is very generous. So, if I'm not missing my opponents, and my grenades are indeed killing enemies, then what the hell is going on? The only theory I have is that because glacier crystals are a new mechanic, and don't function the same way light based grenades do, the game code is seeing the kills from that grenade and something separate from base grenade kill conditions, and is registering the crystal explosions as the new mechanic kill and not a "grenade kill." Bungie, wither you reply to this or not, I implore you to look into this issue. With Rime now in the game, my idea for a defense-based titan build is very viable, but the idea means nothing if all the grenade mods based around getting grenade energy or health on grenade kill don't work properly. (also, would it be so bad if you made a aspect that gives 3 mod slots with ice floaters please? I need slide and melee crystals in my life, but the 3 slots max is kinda sucking the soul outa me.) (note: I will be adding further testing notes on the season mod Impulse Recycler once I unlock it, but I have a feeling that it will act alot like the other grenade kill mods)
