Meteor 40 would be better than Meteor 30 with 400% Explosive.
if you feel that you were doing better with the spike damage with Explosive, you can always put it back. Meteor 40 is more consistent damage over time.
Meteor 40 is only 3 Meteors dropping, but when you get Meteor Proc, 6 Meteors drop! also, Meteor Proc has same cooldown as the skill, OH!, and with Elements Set, even more Meteors! plus, I see you have Aftermath Bonus, so Meteor is doing 2550% weapon damage, half for the 2 extra meteors. if you get Elements & Meteor Proc at the same time… 9 Meteors!!!
with Shatter having a stun chance, the Taunt & Fear from Aftermath is going to be bad for monsters.
I’ll make a build and check that out. I won’t have Meteor Proc or Elements Set so that I can make sure if MA & EAC does or doesn’t show extra Meteors instead of just boosting damage. also with Meteor 0 and Meteor 40 to compare. oh, my poor crystals!
It’s possible that, since Meteor gains +1 Multi Attack Meteor at Rank 11 and 21, that when used with Discordance, it shows extra Meteors when using Multi Attack and/or Extra Attack Chance.
what usually happens, the Special that is changed to Primary Skill with Discordance just gets a damage multiplier from those affixes. MA +4 is +200% DMG or 3x DMG.
starting at 0:08 secs, It starts dropping 5 meteors.
I switch my Element (Pet) to a different pet to avoid confusion. If I equip my pet with Element Set, It can drop up to 8 Meteors at once when the Element set procs. (Just ignore the 3 Small Meteors, it’s from MH Mythic Skill “Apocalypse”)
