While this skill can already buff minions in a way, I think it could do even more, thus I would love to see this node added somewhere:
Enflamed Arms: [0/?] Minions within range of Infernal Shade’s damage radius have +X fire damage, increased by 50% for melee attacks.
I think this would help with a few things. Notably, I think melee necrotic minions are in a slightly rough spot compared to their ranged counterparts, so this would alleviate that. But, it would also help all minions by a pretty decent amount, particularly Pyre Golems. Could obviously be adjusted, but I think it would be a nice buff node!
