What can you expect in the remaster?
The original Trials of Proelium was my first published game and I've come a long way since then. I wanted to return to my roots and improve my game years later. The list of improvements became so big I felt a full remaster was justified. For the remaster, you can expect:
Improved art and visuals, including UI design, text font and character portraits
A better combat system and skill trees
Random events that can make each play-through different
Other masters can now be killed or spared, both options having potential consequences
Some dialogue improvements and glitch fixes
Skin customization options for your ship
Some new mechanics and more content
And more!

Happy summer!
Steam summer sale is officially here! We also have a few days left of pride month, so Trials of Proelium is currently 80% off to celebrate the love for yuri stories and characters. If you still don't own a copy, now would be a great time to get it. ːReeneOKː I would also like to share a tease. A sequel is likely to happen. It is still in the early planning phase so it will take quite a long time for it to come out. It will take place in the future and you will play as a new protagonist, but Letha, Yoni and Squalus will be in the game and it will have a yuri theme as well. ːYuutoWhoaː For now though, grab some beers and enjoy the beach with Yoni at one of the sunny districts of Proelium. Happy summer!Read full article on Community Announcements (Phantasmal Warlock)Patch NotesOfficial
Update V4
Hello emperors! I am happy to announce the new update for the game. ːReeneOKːPlease note: Some of the updates listed below will only work when you start a new game! Installing the update or redownloading the game should not ruin your current save file though. I did some testing and it looked alright to me, but some of the glitches and stuff will still be present in any old files. This update is a pretty big one.Big changes:Added a drawn scene when you pick the snuggle option with Yoni while married.Fixed an error where using Yoni's ultimate skill too often would cause it to level up and increase the stamina requirement, making it unusable over time since Yoni's stamina does not increase.Finally fixed the error causing Letha's and Yoni's equipment to randomly unequip itself at least once or twice during a playthrough. It seemed to have been caused by a conflict with the equip level requirements. I have removed all level requirements, but have balanced this a bit by making crafted weapons require more materials to create. Equips never unequipped themselves during the two full playthroughs I did while testing these changes.Increased the difficulty with some bosses a little bit by reworking their critical hit chance, weaknesses and skill damage. While testing, I was closer to losing boss fights more often. A few minibosses are now immune to Letha's insta-kill skills like other bosses are. Smaller changes:Letha's dialogue with Lee after defeating Cupide should now be slightly different if players have spared every master up until then. Instead of feeling conflicted about killing masters, she will instead be worried about her decision to spare everyone. Fixed a few grammatical mistakes.Fixed a few tileset errors (being able to walk out of bounds).A few very powerful scrolls are a bit less effective now.There was an equipment you could buy that could not be equipped. Now it works.Other tiny details fixed/changed.There was a rare scene that could be triggered by doing thing...Read full article on Community Announcements (Phantasmal Warlock)AnnouncementsOfficial
The future
Hey emperors! The game has been out for a while now and I have discovered a few things I would like to improve upon after playing the game again. Mostly fixing glitches I found, some grammatical improvements, stuff like that. Also, Trials of Proelium sold surprisingly well during the last RPG maker festival, so I have commissioned a drawing of Letha and Yoni that will be shown when you pick the snuggle option. SFW, but super cute! ːAsaː The update is going to take a while. Still waiting for the drawing and still much to do, but here's a tease while waiting. ːReeneOKː Thanks for reading! Stay tuned!Read full article on Community Announcements (Phantasmal Warlock)Patch NotesOfficial
Post-launch update
Hey emperors of Proelium! As is often the case, a few smaller issues were found after launch. Several of those issues have been fixed. If any other issues are found, future updates may come out as well. Thanks for reporting things to me, it helps. ːReeneOKːThe following things have changed: - Cooked food is no longer worth anything to an NPC to fix a money exploit. Uncooked food can still be bought and sold. - Fixed a few typos. - Fixed Yoni not having an opinion of Serenity Island. - The demon down at Snowfox prison did not disappear after finishing her quest and could softlock players that talked to her again. She should now disappear after the quest is concluded. - To avoid confusion at Sodalitas Island, if player's try to use a ship that does not belong to them, Letha will make a comment saying it's not your ship. - Fixed an issue with a letter showing the wrong text when read. - A few other minor tweaks.There are a few things that are tough to improve due to the engine's jankiness, but I will try to improve the game to the best of my abilities if more issues show up in the future. Thanks!Read full article on Community Announcements (Phantasmal Warlock)AnnouncementsOfficial
Remaster is out!
Hey everyone!The remaster is finally complete! With reservations for potential glitch patching in the future, but it's otherwise fully complete now. Thanks to the support from everyone that bought the original game! Your feedback helped me make this remaster possible. The remaster comes with new content such as: - Gothfair and Snowfox Valley expanded a little - Several new islands to explore - A new treasure map quest, a love trail quest (requires Letha and Yoni to be married), and more - Defend the fortress mission added to the Port Commercia fortress after Cupide has been defeated The remaster also includes: - Improved turn-based combat system, now more standard rather than the basic engine system - Overhaul of many skills, including Letha and Yoni each having one ultimate skill each. The ultimate skills and some other skills are stronger than before, but now requires some stamina to activate - A nemesis-ish system including random events (selected at random at the start of a new playthrough), options to kill or spare other masters and consequences, both positive and negative, from such choices - Some new weapons and ship skins you can select (talk to Samuel to see the list of skins) Other improvements: - More visually appealing UI and text font - Character images for Letha and Yoni used more often and now look a bit sharper than in the original - Some minor glitches and typos fixed - While Yoni is in the party, press Q to open a social menu. You can ask for her opinion about the map you are currently in, or select random chatter to get a random dialogue between Letha and Yoni It would be super appreciated if you would like to leave feedback if you find something I missed to fix during testing. And it would also mean a lot to see reviews for the remaster. Thanks! ːReeneOKːRead full article on Community Announcements (Phantasmal Warlock)
