Bonestorm projectile

Scattershot - optional
1. +mana cost
2. +charge speed

Explosions carry over to last projectile eg. projectile chains then pierce then explode.

Chain - not so great atm
-to low dmg
+clear

Fork - bad
-low dmg

Pierce - only for clear/AoE
+helps with clear fair bit by carrying explosions deeper into pack
-swap on boss
-if projectile ricochet first (after missing any targets) then it's followed by pierce which will negate explosion on first target

Ricochet - great counter to Bonestorm poor accuracy (ground works to)
+many projectile can miss
+stat appear on jewels
This is arguably as good as dps gem, unless you have target wide enough to take all projectile wide spread or cause larger enough explosions on each cast.

Chance for additional projectile(eg. 30% chance for 2 additional projectile) - bad
-only works per cast
-to much investment for low outcome

Redflare Conduit Unique armor allows for consistent power charge without downside.

Any tips appreciated.

I'm currently using:
-Splinter support (armour break)
-Pin support (for power charges)
-Scattershot support (for quick channel)
-Supercritical support (for crit bonus)

Still not sure if this is the best setup to be honest but would like to know what others are doing with Bonestorm, this gem is so cool in my opinion

I'm thinking of trying to replace Scattershot with something else and picking the Chance to fire additional projectile tree nodes, it appears that those projectile are considered per stage. For example, by default you gain 1 projectile of bonestorm each stage and lets say you rolled 2 additional projectile from the tree nodes, what will happen now is that you will gain 3 projectiles per stage (1 by default and 2 from the tree) which will make you channel faster. This is 100% pure RNG so becareful i guess, in theory if you lets say roll 10 extra projectile this means that you will gain 10 projectiles per stage which means you will have full channel in like 0.2 seconds which is kind of cool lol
