Taurog berserker still walks all over VHoS even with the corrosion changes. Turns out, attacks that do 0 damage don't trigger corrosion (probably for the same reason attacks that do 0 damage don't trigger might's errode effect).
Just do blahblah first. I forgot to prep a burn salve and 1 from the shops was enough to beat indom.
edit: Ya, and dragon isles is still a simple win too. And somehow I ended up with more damage at the boss on my human run than I did on my orc run. Not sure how that happened, I'll have to check the sums.
Ok, it turns out that, if you plan to hit level 9, humans are just better than orcs. Not even new orcs, old orcs..... so yeah, they completely trash the new orcs. In every scenario. Taking the tri-sword just rubs it in, taking taurog is more base damage = more rubbing it in.
And to even scrabble at humans feet orcs need to hit 600 cp, which requires buying some stuff from shops which is even harder this patch. Especially with the tri-sword money sink.
Anyway, here's my maths
