After seemingly weeks of lost wandering... I finally found myself!
Raz seems a bit of a bastard (which is fitting I suppose

)...
I have beaten him with Battlemage only so far. Wizard attempt bare handed got nowhere (kept leveling Raz up- only being able to deal magical damage to 'that' form). Warrior got nowhere also- only being able to deal physical damage ends up leveling Raz up.
Neither one "Died", just got stuck in a loop between boss forms (Raz levels up, knock him down only to have him level back up/repeat..). Perhaps Avatars idea of limiting health pack respawns would end the loop (ending in player death/forfeit instead).
Corruption nuances took some time to sink in (what they do to player/opponent is not immediately obvious despite descriptions in opponents combat panel

). Took some time for it to sink in that Raz was getting overhealed by left over health packs also (in spite of him telling me so..

).
I don't seem to be as persistent as Avatar. Don't have the persistence to blindly try every class with every combo of weapon/armor. Haven't tried Warrior with staff to try to deal magic damage with him yet... (hmm..). 'edit' - Just tried that and succeeded!
Bare hands has not worked out, can't deal any physical damage to 'that' form.
I can't find a way to beat assassin challenge with staff and plate either.. leaves assassin at level 2 for me. Warrior also stuck at level 2 (need to reach 36 attack but not sure where/how/combo to do that with). Dagger also stuck at level 3 (level 2 assassin with level 3 dagger can't seem to beat Raz, just keeps leveling up his physical damage form with # of attacks needed).
Perhaps some hints at what to pay attention to or what combos to try and when for us non persistent types who still would like to make progress (probably to come a bit later in development..).
Also perplexed about Trees. Are these to visually 'fill in' the town area to make it seem more revealed/completed?
What is the "New Roads" marker intended to do? Seems like an empty achievement at this point. Another visual upgrade to town perhaps?
The new player info panel is much more informative. Took a bit of experimenting to get familiar with how it worked but eventually got used to it and it seems to function well. Found a 'Villager' class somehow while in assassin challenge.

It seems that clicking on the red crossed swords markers that state needed achievements to reveal them should/could take you to that "dungeon" with required class/combo to win the achievement. This would be more intuitive I think than having to track down the right dungeon and recall what class/weapon/armor was needed for that achievement.
Thoughts on Combat prediction... It is there but is not very obvious/intuitive. Perhaps having it run straight down the left side of the area it is in for the player and the right side for opponent rather than top-left, bottom-left, top-right, bottom-right in a square and then the same right below for opponent in same zig-zag/square configuration as it is now (too many directional shifts in calculation makes it awkward to follow at a glance). Also, if possible, show a different level of shading on the health bar to indicate result after next attack (like in DD).
