yeah, lets see a brief current rundown.
Tutorial is kindof bad.
Basic game system.
1. you claim a "cornerstone". A cornerstone is a 16x16 plot that you and only you can build on. this plot actually moves with you. When out adventuring in the world, you can find cornerstone plots in the wild, which you can summon your cornerstone to. Mobile base of operations. it vanishes from the last place you had it. Currently, can not port back to it, short of manually suicide.
You can build your crafting things on it though.
2. Then you can build a clubworld. wiki on this is a bit out of date, as club worlds, used to be homeworlds, etc. This is a private world you build. starts out small with 1 biome. you need to craft more sectors to make it bigger. can also invite friends, to join your clubworld, and they can build in it as well.
3. the hubworld. Acts like the town in realm of the mad god. trading, portals to random players club worlds. you can place your cornerstone here as well. trade bench, cosmetic, etc.
And portals to the adventure worlds.
4. Adventure worlds are split into level groups. 1-3, 3-4, 5-6, etc to 10+.
(level 20 is cap)
Adventure worlds have monsters, and crafting components from biome spawns. undead and fey areas spawn enchanted treestumps, fairies in ice, and fae drop fairy dust, etc.
5. in adventure worlds, there are random monsters, and quest areas.
A quest area will be a tower looking thing, themed to the biome. sometimes a small jumping puzzle +boss, other times just monsters+boss. Dungeons rae larger complexes with multiple bosses.
Quite a few designs. Although mostly just cosmetic really.
6. 5 classes atm. 2 are free from start. (knight and gunslinger) all can be unlocked via daily quest gold gain.
Mounts are also via daily quest gold, in the cash shop.
7. loot is aoe shared regardless of party. If I mine a golden soul, and you are standing near me, you get one too.
And no, not quite that twitchy. meant more in terms of the world designed class design. 3 "skills", one of which is an ultimate. 5 classes atm, but really I expect them to keep adding ala, rotmg. The portals to adventure worlds really feels like ROTMG's instances. Then running around looking for bosses/quests. dungeons are not quite like rotmg's dungeon portals, but not exactly super dissimilar either.
Combat is definitely slower, and there are not that many creatures, and no bullet hell at all.
Have not gotten to shadow arenas yet. So if those are like ROTMG's farming, not sure. would be funny if they were.
