Hello… I am using a frenzy barbarian build with BOTD (60% ias) and Doom (45% ias) runewords, both berserker axes. The whole amount should be 105% ias, not counting what you may have on gloves, belt, etc. but the only ias that seems to count is the one of the weapon that is on the left slot as you look at the screen, or at least this is what can be seen in the advanced character stats tab. I get the feeling that my barb does not attack fast enough as I have had a similar character before. Thank you!
Same for my barb! My crushing blow and life steal isn’t stacking it only catches the stats on the left slot weapon
Nope, frenzy ias calculation does not calculate it with simply addition
You actually get the average of both
From one of the fan site i have found the formula
Frenzy:
item ias = [120 * (total item ias - larm ias) / (120 + total item ias - larm ias)]
speed increase = 70 + average(rarm wsm, larm wsm) + skill ias + item ias + fanat ias (175 >= speed increase >= 15)
frames = {256 * 17 / [256 * speed increase / 100]} / 2
attack mode on weapon count only the one you swinging, will not stack with weapon in the others hands. e.g. IAS/curshing blow are attack mode will not stack, +mf/dex/str not attack mode will stack.
