Warcry Damage Scaling

I was trying to find any weapon to work with Seismic Cry to help scale its damage and was really disappointed when I tested wands that it didn't increase. Wands have a prefix that reads approximately "Gain X% of damage as extra Ele Damage". No where in any of the tool tips does it show any implication that this only works for spells. Warcrys are neither attack nor spell so finding scaling for it is quite slim and this option not being available with not indication as to why it doesn't work sucks. The last thing I have yet to try is using the Malice Aura, this gives a debuff to creatures that gives you +10% chance to crit and I'm hopeful that it will work but I doubt it. So for the time being the best weapon looks to be a sceptre with +str/+int using the jack of all trades node in the tree.

Go for physical damage nodes. If you don't think there's enough of those, grab Avatar of Fire and go for fire damage nodes instead.

Considering there are only ~15 nodes for nondescript physical damage and they have a decent spread converting to fire wouldn't be bad. The downside with going fire though is now you have to deal with fire res, Seismic ignores armour but the fire res will still be there. Still doesn't fix that there is no weapon that you can use for any benefit.

I have already tried multiple ways to find a solution to increase War-cry damage,

Convert to fire damage with Avatar of Fire. This is not the best choice because it decreases the damage from 100% to 75%. Additionally, the node for increasing fire damage is far away and not worth investing in since it is distant from many essential nodes for Warbridger.

Use the unique item "Sacred Flame Shrine Sceptre." Yes, this scenario works because the skill's damage information increases. However, I’m not sure what went wrong. It’s possible that Seismic Cry is not marked with element damage or something else, as it is not considered fire damage and doesn’t trigger the Ignition status. (Tested by casting on fire skill = nothing, still 0%).

The better way would be to:

You also can use and Omen Sceptre to put a Crit debuff on enemies, I've tested it and does allow for SC to crit so there is potential going for a crit build of some kind.
Maybe instead of shooting for 1k str you shoot for 333/each and run jack of all trades which gets twice as much %dmg for the same 1k stats and you could still run brute str and still get some good %dmg but i'm not sure if it would be worth getting both.
