Patch v15.04 - Balance Adjustments, QoL Improvements, and Bug Fixes

Idle Hero TD - Tower Defense RPG · published 16 Mar 2026, 04:39 UTC

All eventsPlayers around this dateRead on Steam

The goal of this patch is to speed up energy gains for mid-game players, and to balance energy farming sources for end-game players.

New Content:

  • Several new upgrades across all menus to buff the Mimic Chest Boss.

Changes:

  • Buffed automation damage, gold, and energy stats and max levels to make them more useful for pushing and dedicated gold/energy runs.
  • Buffed Arbalest's Energy Source skill from +0.5% to +1% per skill power and also accounts for super/ultra energy chances.
  • Buffed Arbalest's Mastery skill from +3 to +5 energy per level.
  • Buffed Captain's Energy Aura skill to account for super/ultra energy chances.
  • Slightly nerfed Captain's Mastery energy bonus on Power Mages from 10% to 8% per level. It is also capped at 30x Power Mage kills, after which the bonus will stop stacking/increasing.
  • Slightly nerfed Power Mage energy bonus from milestones and synergies (by about 5%).
  • Buffed Power Plant spell to account for super/ultra chance and also scales up based on Arbalest and Captain’s mastery levels to ensure it stays useful at end-game.
  • Reduced the chance of the Golden Boss kills daily task appearing until you have more spawn chance upgrades.
  • All "Golden" bosses (mimics, goblins, power mages, and training dummies) have 10% more HP than the original bosses.
  • Increased the max level of the Automation Ultimus Min Wave Setting to 15 (wave 80k).

QoL Improvements:

  • When a hero has "No Skills" target setting enabled, it will still show his damage under him, but his skill bar will change to red.
  • Added a new "chilling" animation when a hero is not attacking or using skills.
  • Added current run Prestige Power earnings to the Stats menu. This will display your earnings based on if you were to Prestige at the current wave plus any earnings from the Mimic Chest Boss.
  • Added more Mimic Chest stats to the Stats menu.
  • Added a better breakdown of rank exp upgrades in the Stats menu (separated by base/flat exp gains and % gains).

Bug Fixes:

  • Fixed bug related to the global range level milestone bonus causing some synergies to not activate even though the hero was within range.
  • Fixed bug where 2x mastery exp chance from the map placement slot bonuses was not working correctly on some aura heroes (Apprentice, Witch, Rogue, Veteran, etc).
