Act 4
Act 4 covers act_4_quest_1 (talk to Ronan at the Town Entrance, which sets the questline AudienceWithTheMayor), act_4_quest_2 (an audience with the Mayor at the Upper Entrance), act_4_quest_3 (a second audience with the Mayor at the Mansion Entrance), and act_4_reach_level_100, a hard level-100 gate that grants a boost-immune 5000 XP reward on completion.
Reaching level 100 is Mythfall's max level per the progression formulas, so Act 4 functions in this extraction as an endgame 'catch up to the story' gate rather than a full act's worth of combat content - it reads as the current tail end of the documented main-story stage data.
Details
Sub-stage flow
act_4_quest_1 - talk to Ronan at the Town Entrance; sets questline AudienceWithTheMayor.
act_4_quest_2 - audience with the Mayor (Upper Entrance variant).
act_4_quest_3 - audience with the Mayor (Mansion Entrance variant).
act_4_reach_level_100 - hard level gate; grants a boost-immune 5000 XP reward once level 100 is reached.
Why Act 4 is short in this extraction
Max level in Mythfall's progression formulas is 100, matching act_4_reach_level_100 exactly - this act's final beat is reaching the level cap rather than a combat set-piece.
The World & Story systems page notes a second island as a future expansion, so Act 4 currently reads as the end of Island One's documented main-story stage content.
