    Alpha 18.4.5

    {STEAM_CLAN_IMAGE}/33209929/1c0d394741b3815b5bfcbcee97809c5a215181e5.png Greetings from the Elteria Adventures team! As we continue working on improving the game, we’ve got enough new features (as well as bugfixes) to bring you this update. We hope that you like it! {STEAM_CLAN_IMAGE}/33209929/5f5577090a31f1599f9cc61c490a93c5c0a35dc5.png Panic Volley. A new ability for the fleeing mobs such as Shroomy and Watermello. If panicked, they start shooting projectile attacks in all directions. If such attacks hit the player, they deal a bit of damage + a debuff (such as Slow). If such an attack hits their summoned allies, it grants them a Shield effect; Bow Stab. Now archers will be able to deal with enemies that come too close! Punching with your bow deals a bit of damage, and pushes the enemy away, allowing you to maintain a safe distance. For now, this ability has replaced the arrow shot, as we are implementing new arrow choosing mechanics into the game for the next update, which will be released with the fixed bow shooting mechanics; New attack ability for Little Boarmelons; Added the animation for the Shroomy’s ally summoning ability; Updated the female model’s damage receiving animation; Updated the critical damage debuff animation. {STEAM_CLAN_IMAGE}/33209929/aede18639042ab7216a8ebfe869f8ed03cba0910.png Fixed the bug that caused items to disappear from chests when you re-enter instances; Fixed the crash related to the double jump; Fixed the animation cutaway issues when viewed from the spectator’s side.

    Incoming: More immersive world, Adventure Journal and more!

    {STEAM_CLAN_IMAGE}/33209929/ccfd6e1b0032b8f7fc68027e3c81da72b5a64e66.png Greetings from the Elteria Adventures team! It’s been an important year for Elteria Adventures so far. The game had switched from semi-realistic to cubic environments with more emphasis on Sandbox gameplay in May, and we’ve collected your feedback through the entire June. After that, we started implementing it into the game in a massive overhaul in order to make Elteria Adventures even better than before, the first results of which you are currently able to see on our alpha servers. Of course, this is only the beginning — after implementing a completely new worlds system, we are currently working on the main gameplay features that are going to take place in these worlds, which will likely take us the rest of 2021. This work can be separated into four big parts: {STEAM_CLAN_IMAGE}/33209929/ca6d9c5a445c5e5e8cab16fe73559760ef5c2a88.png We are currently working on both improving the visuals of Elteria, and making it more immersive. And in order to do that we are: Reworking the way the islands of Elteria are generated and adding details, to make sure they all look diverse, interesting and fun to explore. Improving the visuals of the nature voxels, with both new pretty textures and reworked old ones. {STEAM_CLAN_IMAGE}/33209929/db207ca1561d258551d633d59071efd8328b511c.png Implementing new and improved behavior for all the in-game mobs to make them more believable. Redesigning caves and dungeons, so that exploring them is even more fun Changing the way music is played, so that it works even better with the gameplay. {STEAM_CLAN_IMAGE}/33209929/a022c1825870da6fb3bbb9ef22931077fd43b0a8.png The fun of exploring the world of Elteria is in a lot of things — new resources, new items, new enemies, new vistas etc. And we thought that it might be a good idea to give one more incentive to venture towards the unknown, which is why we are working on implementing an Adventurer’s Journal. {STEAM_CLAN_IMAGE}/3320992...

    Megapatch 18.0.1

    {STEAM_CLAN_IMAGE}/33209929/f82f84a2183d8bf9c6eb7381168c0d31e2d8d8f4.png Greetings from the Elteria Adventures team! The 18.0.1 Megapatch is finally here! So, without further ado, let’s check what it has for you in store! GAMEPLAY AND THE WORLD: New system of Elteria’s outer worlds: rather than one big interconnected map, there are many different worlds differentiated by tiers, each with its own lifespan and autoreset timers. {STEAM_CLAN_IMAGE}/33209929/24917cda2528ea96f5d81a1cd1571d4694f6b386.jpg New, separate PvP world, for all your PvP needs! You can find it among the Tier 2 worlds! {STEAM_CLAN_IMAGE}/33209929/30b0fbceed93ff75bc802d42deb533fb44908760.jpg Overhauled penalties for death. Now if you die, you drop a chest containing a random set of items from your inventory (with some exceptions). The chest disappears after 10 minutes, and can be only looted by you in the first 5 minutes, and by any player at all in the remaining 5 minutes. Major reworks of the crafting system, including reworked recipes, drops, new crafting stages, etc, in order to make crafting more natural and engaging! Moreover, all recipes are now divided between four modes of crafting — with your hands, on a Workbench, on a Construction Workbench and in a Cauldron. Added craftable Beds that you can use to skip in-game time in your private world. {STEAM_CLAN_IMAGE}/33209929/582728c7be5e0249241be96cccc6e1c5daf22e6a.gif Bouncy Gel blocks! Added new craftable Gel blocks that you can use as a bouncy trampoline! Reworked the mob spawner, so the mobs can now spawn depending on the lighting conditions, so you could use light-producing blocks to prevent mobs from spawning in an area. Speaking of which… Updated the mob roster, featuring new drops, new (or updated) abilities and even new AIs for some of them! Mobs have returned to the Elterian underground. You can once again encounter mobs while in the underground caves. Ah, and we improved the way ores and rocks you venture down there for are generated. ...
