I am recently testing some mechanics with abilities+weap dmg types+passives myself so just to add a few things =)
i dont do it as professional as u guys ... lack of time ;/
well here some test/ideas :
for example the on hit chance to stun with paralysis+spectral blade->deep cuts (88.8%) with a weapon doing LIGHTNING dmg equipped is pretty awesome cauze
if the tooltip says u do weapon dmg (and not xx% weapon dmg as *INSERT TYPE* dmg) u do the type of dmg on ure weapon.. -> abilities "overwrite" the weapon dmg.
I did not found a weapon yet with xx-xxx dmg + yy-yyy TYPE dmg where y>x so
Maybe the "bigger" element dmg will be the boss... idk..
tested it with 6 different crossbows (ALL THE ELEMENTS!) with a total of 9-11 weapon dmg + 1-2 type dmg of each type, on each crossbow
Btw: the first 3 zombies in act 1 (all except inferno-> there it is most of the time Oo) 'almost' dont hit u if they would kill u with that hit -> pretty nice for some tests =)
i did test it with just the crossbow autoattack (means 100% weapon dmg) and some skills
i also tested the familar dmg types + some passives
seems like the on hit does not (or almost not) work but the 100% chances to slow/do more dmg with temporal flux / conflagration do work with familar attacks (and others like hydra obv.)
obviously the familar atk speed scales with ures
(think on the fact that atk speed increases tooltip dmg only, NOT the actually numbers popping up... the familar also shoots on almost every action of ure hero .. even tp :D )
so familar+sparkflint does actually +12%dmg + 10% increased dmg from conflagration total of 22% increased dmg of all sources (+ the 20%weapon dmg of the hit) .. pretty cool^^
further more i need to test the +x%TYPE dmg on several items
+3 fire dmg increases fire dmg skills AND weapon dmg skills if a fire weapon is equipped
id also like to point out that some skills also "scale" on hit with RANGE.!?!
for ex. Mammoth Hydra
It does more dmg, the closer the enemies are to the Center .. (did not test with life/hit yet -> time missing :E)
Also Acid Cloud - Acid Rain on the WD works that way.
look here for on hit WD Maths :
seems like dmg scaling on distance to the center is similar to the on hit effects (all of em) on those skills ... pretty scary ideas in my mind .. stark winter maybe needs further testing? :S?
sry for bad english/gramma i am tired testing all night long :p
oh and stick it pls <3
