Thanks for that. I was able to pick up a few more things now that I could fullscreen it at high resolution and more importantly, pause.
Instead of skills having a number in the 1-20 range to denote power, Skills now seem to be in one of three categories of power: Novice, Adept, and Master.
Looking at the skillbar, there are a bunch of new icons I've never seen.
Mass Healing - Hydrosophist - "Heal all within an area [6.0 m Radius]." All I can say about that is FINALLY.
Rain of Arrows - Expert Marksman - "Let a shower of piercing arrows rain down on your enemy. Deals piercing damage to EACH enemy." Radius 4.0 m.
Winged Feet - Scoundrel - The skill that lets you float above surfaces costs 2 AP, lasts for 4 turns and has an 11 turn cooldown.
Crawling Infestation - Scoundrel - "Plant a monstrous egg in an enemy close by. Unless the target resists or succeeds a [Bodybuilding] saving throw, its mortal shell will give way to a monster as it comes out after three turns."
Netherswap - Aerothurge - "Select two characters of equal size. One of the characters can be you." Meaning, one doesn't HAVE to be you. Oh, that is so useful.
Lightning Strike has been renamed to Thunder Jump.
Storm still randomly picks 6-10 targets and does heavy damage with a chance of a one-turn stun. Oddly enough that build has 0 turn cooldown for it, which suggests you can spam it as long as you have 9 AP a turn.
You can look at your party members stats and Talents and such mid-combat, which you couldn't do before. You used to only be able to mouse over them with Ctrl and that would only work if you had high enough Loremaster.
"Beta v1.0.81.310 Classic". Presumably "Classic" refers to the game mode, and likely it retains the enemy placement and difficulty settings of the current game.
They're not even announcing their new game(s)
Probably because the games are not at a stage where there's anything to show off yet. They've been working on them since August 2014 at the earliest, possibly later given how much stuff they've wanted to still do with Original Sin still. The first mention of new games in production was late December. At this point they are not even at pre-pre-alpha, so even though they're using the D:OS engine, a lot of assets would still be placeholders, maybe not fitting the design of the new game.
And so there's no point in showing things off now that are guaranteed to change.
