v0.3.5
Fixed more issues with the dragon fortress and events surrounding being captured and facing the dragon in the Colosseum. Added an interaction to the mysterious lightning barrier in the Secret Grotto. Slightly improved clarity during item use context in the character menu. (UI is not final.) When a status effect cannot be overwritten it will display a "Null" text instead of the usual text. Fixed a bug with the load menu on the start screen that would not return to the start menu when closed. Updated the input plugin. Some prompts will change glyphs to reflect the current input device, more to come on this.
Update
v0.3.3.1
v0.2.9.4
Mostly balancing in the early game and overall battle polish. As long as there are no major game breaking bugs discovered then new updates will slow down again as I return to working on chapter three content. Slightly reduced the global delay between turns. Characters using a melee attack now signal the end of their turn after hitting the target instead of after returning to their battle position, allowing the next character to start their turn much quicker. Animation charge times on several abilities have been reduced. The "move into position" animations when a battle is triggered have been refined. If a character is too far away when a battle is triggered, they will be teleported into position. Hero and Ash have a snappier new "return to position" animation. The battle positions of several encounters (particularly in the aqueducts) have been brought closer together to reduce melee attack travel time. Enemies will now more frequently target hero for melee attacks over Ash and Lyric. Magic and Ranged abilities are unchanged. The damage variance of melee attacks has been significantly reduced in most cases, making it easier to see progression. Empty battle command groups are now properly hidden in the command menu. Removed the Wait command under normal circumstances. Added Ward to Ash and Lyric. This increases magic defense for a turn and restores a small amount of MP. Removed the Backstab ability from Ash as two guaranteed criticals was almost always the best option rendering a lot of other abilities unusable. Moved Ash's Phantom Missile to the magic group. Increased the damage of Ash's Shadow Orb spell. Changed the cost of Ash's Ethereal Strike and Spectral Sever from MP to HP. Increased the scaling of Lyric's Cure spell. Adjusted the levels of some enemies. Increased the number of enemies in several encounters in the aqueducts and goblin encampment. Removed the experience reduction from being over an enemy's level. The enemy ability Poison Spit now inflicts a persistent poison status until cured or end of battle. The damage proc has been reduced. Hero's Poison Spit is unchanged. Added some crates just before the Aqueducts that drop antidotes. Changed the treasure chest above the Tavern to be an elixir instead of a potion. Made wolves even weaker to fire. The wolf's Howl ability can now be disabled by Silence status.
