Bone Spirit’s a pretty awful skill and it can just sit out, it doesn’t have to be rolled into something else until they can actually make it worthwhile.
Bones of Rathma 2-Piece Set: Your minions reduce the cooldown of Army of the Dead by 1 second each time they deal damage. Your skeletal warriors spawn faster, and your revived minions and Skeleton Archers no longer expire.
Bones of Rathma 4-Piece Set: Your minions no longer take damage. You gain 1% damage reduction for 15 seconds each time one of your minions deal damage. Maximum of 75 stacks.
Bones of Rathma 6-Piece Set: Your Revive, Command Golem, Command Skeleton, and Skeleton Archer minions do 10,000% increased damage. Each active minion increases the damage of Army of the Dead by 1000%.
Defiler Cuisses: Revive, Command Golem, and Command Skeleton minion damage is increased by 200% to 300% for every Revive minion that is active.
Golemskin Breeches: Gain the five runed golems at all times and reduce the cooldown on Command Golem by 20 to 25 seconds.
New item Bonds of C’Lena: Army of the Dead and your Revive, Command Golem, and Command Skeleton minions deal 300% to 400% increased damage. Your Revive, Command Golem, and Command Skeleton minions deal an additional 2% increased damage for 5 seconds each time Army of the Dead hits an enemy.
There was really nothing wrong with redesigned Rathma aside from a bad invulnerability interaction that was too easy to maintain (a fault in the passive that was already fixed) and the inclusion of another non-minion spell being the focus of damage, turning minions into inert buffs.
This rework addresses that, brings focus back to minions and AotD, and for the most part preserves AotD-based speed variants like wudijo’s, while providing options and additional active play elements and utility - all without attempting to fundamentally redesign the redesign or significantly disrupting other builds.
This should be the starting point for tuning testing rather than burying the set for an entire season.
