the skill smite auto hits....so wheather ur in pvp, pvm, ubers, nomatter no need for ar and their def dont mean shit

high average dmg and every hit is very consistent because

for instance on a 15-30 base weapon

your doing 415-430 dmg

Astreons works well on uber smiter too.

yea it did, but grief was a lot better

i did uber with both, astreon @ 100cb and grief @ 70cb, grief > astreon

then it's either your imagination or you lack attack speed with astreon's. get more ias

Most likely this.

Because CB takes away a certain percentage of your enemy's current life amount.
After some time a much bigger dmg will be better than the CB.

Also 70% CB is absolutly fine, 100% ain't needed.

Only imagination!!!

Here the Smite sequences:

on Page 2 there is the common Astreons Setup with the sequence

Astreons > All

BTW: There might be situations where u have felt 100% CB with Grief - but u definitly don´t have 100% Math speaks a clear language...but all in all - all 3 Weapons (Astreons, LW, Grief) have really low differences in Damage.
Math says:
Astreons>LW>Grief

Feel free to use the weapon u like most
