To go along with the preview TWV have dissected the video, better than I could have done may I add!
# Damage numbers! This not-so-immersive (but hugely important for PVP and general powergaming) feature is there in TWII!
# Immunities shown for Giant Ants: poison and bludgeoning. Why can't it be squashed? Who knows...
# Not-seen-before part of Gandohar's castle shown - the rec-room (or something...) with pentacle carpet, cool dragon statue and a working dynamic-reflected mirror. Perfect for the vain, slightly effeminite evil ruler.
# Freeze framing allows to witness a lot of the game's inner descriptions for items. Expect names like "Orc Slayer Helmet" or "Elegant Mincer".
# For Armors, there's an indicator of parts of set possessed (indicating there're true armor sets to be found). Bonuses on the items include, like in TW1, stat increases and skill increases. One particular skill piqued our interest - it's called "Frozen Arrow"...
# Armors also show negative impact on accuracy, with amount being clearly larger for heavier armors. It'll be interesting to see how this pans out in mixing/matching for archery purposes.
# Highlighting unequipped armor items displays difference in basic stats in green (upgrade) or red (downgrade) from existing. It's not as full as a full comparison uni-scroll, but it definitely saves HUD room.
# Magic armor (cloth a la Gandohar) contains innate bonuses to willpower (by percent!) to sweeten the deal for dedicated mages! However, the protective stats against physical attacks seem to be negligible...
