    Patch 1.2.5

    Endless ChangesThe Zone Level Multiplier in endless runs now starts scaling much faster after zone 4, but it still has the same cap at map 32. This is intended to have a more distinct separation between the early, mid and late parts of the progression curve in an endless run:Zones 1-4 serve as the early part of the run where you should have plenty of time to build a starting team.Zones 5-16 serve as the middle part of the run where the difficulty starts ramping much faster and your team really starts to get tested. Notably, you now reach zone 16 with a 400% multiplier (from 270%), and this is still the earliest zone where you can fight the unique endless boss.Zones 17-32 serve as the late part of the run where min-maxing your team becomes the focus if you want to keep climbing and reach the difficulty cap at zone 32 with the 1000% multiplier.Mastery ChangesReserved Mind now requires 2 Mastery Slots (from 3).Blood Conversion now requires 2 Mastery Slots (from 3).Temporal Priority now requires 2 Mastery Slots (from 3).Amplification Pact now requires 2 Mastery Slots (from 3).Life Oath now requires 2 Mastery Slots (from 3).Master Navigator now reveals 6 random areas on map start (from 5).Exceptional Chests now grants +20% Influence Chance on a random chest per map (from 15%)Rebuke now grants +10 Thorns at 3 points (instead of +100 Armor on Wounded).ChangesYour mastery loadout is now shown above the portals before starting a run, with a clearer visual of empty mastery slots you could still fill.Your alternate dialogues chosen in each zone are now displayed below each portal. This allows you te easily see what dialogue branches you haven't chosen, what attributes you need to chose them, and thus what boss masteries you're still missing.FixesFixed combats not ending if the last enemy you killed was one of your own characters with the charm debuff. Combats now end correctly if this happens for either team.There are still more patches we want to make to keep adding quality o...

    Patch 1.2.4

    Endless Runs ChangesWe want to have a difficulty cap in endless runs to serve as a benchmark for your teams and a good stopping point if you only care about beating the content. The thing is that some players want to keep going after that to min max their teams, but we felt the difficulty cap didn't provide enough increase in difficulty for those players.Nerfing player power across the board in order to make the difficulty cap harder would make things too hard for new players, but we also didn't want to just make the difficulty cap harder without giving enough time for players to prepare their teams for the added difficulty, so we knew we had to extend the journey to reach the difficulty cap as well.Endless runs still progress in difficulty the same way until map 16, where they reach a Zone Level Multiplier of 270%, but now that multiplier continues to increase up to map 32, reaching a Zone Level Multiplier of 1000% and serving as the new difficulty cap.Notably, the masteries from the unique Zone Boss in endless runs can still be unlocked at map 16, and there is no added reward for beating the boss at map 32. The intention is that players can feel satisfied after getting the rewards from the boss and stop there if they don't care about min maxing their teams, but if they do the game now provides more progression towards the difficulty cap, making the experience more interesting to beat and more rewarding once you get there.It's important to state that our intention with endless runs as the hardest content in the game, is that only above average teams should be able to beat the unique Zone Boss in map 16, which is the earliest you can fight him. And only the best teams in the game should be able to beat the boss a second time in map 32 at the new difficulty cap.We also did a balance pass to prevent some enemy skills from scaling beyond intended numbers while playing with high Zone Level Multipliers:Omen now only gains 5 Hidden Seconds with her Shadow Step skill (inst...

    Patch 1.2.3

    ChangesItems and spells in the collection now show their quality upgrades.All maps now have 1 less normal combat and 1 more superior combat. Besides the additional difficulty, this also gives the first map more interesting navigation decisions and buffs how many consumables from superior combats you can get per map.The mastery trait Mind now grants 30% Skill Resistance on its first bonus (from 20%). This means that the first bonus of Mind is no longer a downgrade when compared to Preparation, which is the base trait Mind replaces with its mastery.The quality upgrades for the Power Conduit spell now grant a base Inspiration amount of 1 / 2 / 3 (from 1 / 1 / 2), but now grant additional Inspiration equal to 3% of Available Mana at all qualities (from 3% / 6% / 10%),The Moon spell now grants its "+5% Maximum Mana per combat completed while undefeated" as an additional amount of flat Maximum Mana, instead of as a percentage that multiplies your total amount of flat Maximum Mana. This means that gaining or losing other sources of flat Maximum Mana won't change how much Maximum Mana you have gained from The Moon, making this bonus more consistent.FixesFixed a rounding error making Attack Range modifiers from items with quality display different values from what they provide.Fixed swapping characters not setting trait counts correctly.Fixed the red portal in endless runs appearing closed after loading a run.Fixed the interactable to save your team in an endless run not disappearing after crossing the portal to the next map. It now also has a tooltip that explains what it does.Post Patch UpdateFixed the forge allowing to enhance merged items at max quality.The Moon spell now grants "+5 Maximum Mana per combat completed while undefeated" instead of +5% of your Maximum Mana. This still lets The Moon be a way to scale Mana infinitely, but it won't literally bug the game by being able to reach millions of Maximum Mana after a dozen maps or so anymore.We're also working on addin...

    Patch 1.2.2

    ChangesThe Bonfire Navigation mastery now requires getting a team of 7 characters instead of 9. This allows to unlock the mastery before endless runs again.The Zone Boss in the Horizon Paths was still blocking many players from unlocking endless runs. Now the phase 2 of the boss has about -10% Maximum Health, -20% Total Resistances, -20% Attack Damage and -15% Skill Damage, but their Convergence trigger skill now grants 40% Maximum Health and Heal to allies on death instead of 30%. This should allow more players to win the fight directly, but it also makes it easier to kill at least one enemy in that phase to start gaining progress through the Ghost system across multiple rounds.The mastery trait Slice was trivializing the new boss in endless runs due to his high Maximum Health, so it no longer grants "+3% Target Health dealt as Piercing Damage on Critical Attack", it now grants "+30% Penetration with Critical Attacks" instead.Forge ChangesPreviously the Forge was the only way to upgrade your items by either enhancing them with an additional random modifier, or merging 2 items together, and each Forge option also has a mastery that upgrades it.Now that we introduced item quality you can also increase the magnitude of their modifiers, which is also a strong option to upgrade your items.The Forge and item quality are both good ways to uprade your items, but in combination they multiply each other very strongly, especially if you were merging items with the Masterwork Merge mastery, which doubled the modifiers of a random item when merging.This created a very high ceiling of power for "perfect" items, meaning the most powerful items you can craft, but it also meant that there was no way for enhancing items at the forge to ever create items that sometimes were stronger than merged items.We decided to make the following changes to the Forge so that both merging and enhancing can create perfect items, but in their own ways, so that sometimes it's better to use one or the ...

    Patch 1.2.1

    This patch mainly touches on the balance of endless runs, since it seems we missed the mark on that and they were much easier than intended, especially the final boss. Since the intention is that these are the hardest content in the game, we want to provide a tough challenge that requires very good teams to beat.ChangesThe new Zone Boss in endless runs was completely rebalanced to be a lot more challenging, with a focus on increasing his defences by a lot and reducing his energy costs a bit. The intention is to allow the boss to last for longer and use more skills to actually challenge your teams.The Zone Level Multiplier now scales higher from Zone Levels 5 and above, with the highest multiplier at Zone Level 16+ being almost double from what it was before.Zone modifiers in endless runs now have 2 tiers. The first one is similar to the previous set of modifiers and will appear from Zone Level 2-8. The second tier of modifiers will appear from Zone Level 9 and above, and will have significantly higher modifier magnitudes.Level 2 bosses from superior combats now start appearing with 1-2 items from Zone Levels 9 and above.Superior combats that grant items to enemies now grant 1-2 more at Zone Levels 9 and above.Superior combats that spawn Level 3 enemies now spawn 1 more at Zone Levels 13 and above.FixesFixed influences from swapped spells not updating your traits in endless runs.We'll keep an eye on feedback about balance, especially on endless runs, and there's other fixes and QoL changes we're working on for the next patches.
