now gives you +50% corrosive lash (Berath) and is fine at lvl 6. At lvl fine the tooltip still says 50% corrosive lash - now it's exceptional. You can't see the qiality in the tooltips, you have to attack something and then check the combat log. At lvl 6 the great sword has +4 ACC and +15% damage (fine) and at lvl 9 it has +8 ACC and +30% damage (exceptional). Whan I calculate the corrosive damage I end up at ~65% and not at 50% though. Target was the CRE_Dummy with 0 DR.
Very weird. I don't know what they mean by "corrosive damage gets calculated correctly" - but it seems this is still not right somehow. Or the math for damage rolls and lashes is totally obscure. Or both.
Still only scales with level and does burn/pierce. No improvement and therefore strictly inferior to Spiritual Weapon except for the double duration. I personally think that a 50% (or +60%) lash is way more powerful than double duration. I still didn't encounter a fight that lasted more than 30 seconds.
I think it is bugged because the penetration bonus for physical damage is an additive, but for lash it is still a multiplier.
