Blizzard's mobile game Diablo Immortal is about to go into limited technical alpha, lead designer Wyatt Cheng explained in an update video. "A small number of players, primarily in Australia, will briefly have access to test the game," he said, "and help us look at our early leveling experience, as well as our midgame systems."
The alpha will feature four out of the final game's six classes: the barbarian, monk, demon hunter, and wizard (no crusader or necromancer). It'll have a lower level cap than the complete game, stopping at level 45, although players will be able to test a paragon system like Diablo 3's to continue improvement past the cap. Unlike Diablo 3, Diablo Immortal will have multiple paragon trees of abilities designed around different playstyles.
Another feature of Diablo 3 appearing in slightly altered form are the randomized dungeons called greater rifts. In Diablo Immortal they'll be called elder rifts, and require keys to open.
The legendary items discussed at Blizzcon last year were mentioned again, with an explanation they won't be tradable and will have to be "self-found". An item-leveling system will keep older legendaries relevant by letting you salvage gear for crafting material to upgrade them, and upgraded legendary items will gain random bonus properties at certain ranks.
As for the storyline, it'll be set between Diablo 2 and Diablo 3, and begin in Wortham. Looks like Deckard Cain is involved, because of course he is.
Finally, Cheng explained how Diablo Immortal will be monetized. "The entire main quest storyline and all future content updates are always going to be free," he said. "We are not gonna limit your game time with an energy system and new classes will be accessible to everybody, without requiring an in-game purchase. Diablo Immortal will be free-to-play, with optional in-game purchases available."
Those in-game purchases will include a battle pass, and items called crests that can be used to modify elder rifts. They might make the dungeon harder or easier, but either way they'll increase the loot you get from it.
