Beira's Flaming Tornadoes - great damage with life stacking

In-progress pob: https://pobb.in/q6p5mBzm6NrG

This build is all about stacking life to get massive ignites from Beira's Anguish burning ground, which we trigger by igniting enemies and therefore self-igniting ourselves via the Self Immolation notable. But this burning ground is tiny; it's terrible for clearing since they nerfed the charm from igniting everyone in your presence.

The new Tornado skill can pick up this burning ground and apply it to every enemy it touches. The fun part is; even though the burning ground only lasts usually 4 seconds or so, the ignite is carried in the tornado for the tornado's full duration, which can easily be 10+ seconds.

We make the tornadoes move using Morgana's Tempest, giving them 60% more movespeed and +1 limit, so I can fire off two of them. Another fun thing; the 'less spell damage' mod on Morgana's doesn't matter here, since spell mods don't affect the ignite's damage (this is also a downside, one cannot use %inc spell damage to buff the ignite's damage, despite what the Tornado's gem description says... I tested this exhaustively).

We use Pragmatism armour to make charms use no charges, so essentially every 3 seconds (the charm duration) we can make a new burning ground to spawn tornadoes from.

Life stacking increases the damage, since Beira's multiplies your life by 5 to get the base fire damage, so 4k life = 20k base fire damage equivalent ignites. This is... a lot. I'm at 4200 life right now and I'm seeing 180k ignite dps on single targets.

Honestly, it's really satisfying to watch the tornadoes walk off by themselves igniting everything in their path. Getting the initial ignited ground can be a bit finicky (I'm trying fireball and flame wall as my main ignite proccers), but once you have that, it's amazing.
