My take on Spirit Walker (tree included)
Idk how to simulate from nothing on PoE ninja but I’d only be taking the 5 minion notables around pain attunement so the actually tree is level 90
The idea is that you can reach 82 max rage while shapeshifting with this tree + a maji talisman which translates to our minions getting 82% increased damage, 102% increased attack speed (thanks to onslaught), 82% extra cold damage (bhatiars), and 30% more damage
The tree itself also has ~200% increased damage for companions and thanks to inspiring ally, we benefit from this, the 82% mentioned above, and our own bonuses from the tree
And for defenses we’ll use lightning coil, goregirdle, iron reflexes, 15-23% damage taken by companions(depending on the ascendancy passives we take), and some armor applies to elemental rolls for large reductions to both physical and elemental damage taken
Our companions themselves will be tanky as well in combination with this tree and a right hand of darkness anoint, and a single life leech roll will allow me to sustain myself and my companions
As far as skills/playstyle goes, wolf pack is our main companion + either a boss or an aura bot if bosses are bait. You want 100% uptime on bhatiars, arctic howl, and lunar blessing, as all 3 affect allies, and pounce functions as both a movement skill and a way to direct our wolves
