Aftershock because it'll proc easily, give you health back, and have good damage. Alternating current won't give you much damage unless you are a 3 eye of harvest catherine or something.

I love doing this type of build but i end up being so easily countered by a single aegis. I wish they would change broken myth, then i would do this more.

This really needs to be changed. Bonesaw and breaking point are great at countering armor. But this just adds a little extra tickle unless you're about to die.

Does anybody know how much of a slow SS does and if it makes frostburn less effective or if they work independantly?

You could actually use shiversteel instead of journey boots if you are more comfortable with krul's heroic oerk. It offers more survivability as well.

Actually just tested this out, and shiversteel, or Shasows empower me, take out a percentage seperately. As far as i can tell. So speed of 100 would be brought down to 36 and not 20

Does this stack with krul's heroic perk? So 80% slow?

True, krul takes a while to get his lifesteal up thpugh and if you get stunned and birst down by 2-3 teammates then you're done. The boots are for escapes anf for making sure enemies don't get away. I'll try it out though!

How long is the cooldown?

It won't let me edit the abilities, i put them in way wrong. Ok first i play krul as a melee tank in the middle of everyone and don't need boots. Who cares about the 10% DMR gets 70%. Crystal power isn't the point of this, it's cooldown reduction and aftershock damage, every 4.4 seconds you can dmr doing reasonable damage and being invulnerable for 2 seconds. And take 15% of opponents health with 50% steal. Then activate a bubble when heath barrier runs out. Dmr again, shield, spectral...
