what is LH meta build ?
This build is more specifically built for using lightning hammer – most conjure heavy builds make use of piercing shards for 20% damage while attuned to water. Since there’s also a 10% modifier in water, the base of a conjure build is 10 in fire and 20 in water. 30/10/10/20/0 is a common varient, as it provides persisting flames and 3 more damage modifiers.
That said, you can use conjures with 30/30/x – but i think generally a LH focused build will make use of piercing shards.
