Update 9 is the most consequential patch Iron Soul Dungeon has received since launch. It introduces a full level-70 endgame dungeon, a permanent buff economy, and a complete companion gacha built around the new Dragon's Grave wave-survival mode.
The headline is the Oathless Castle. Its Trial variant enforces a 28,000 Power minimum, which functionally requires the Grey Sword, the Noble Cuirass, and the optimal headgear to clear. Hell Mode, which is scheduled to follow, will scale these numbers even higher.
On the economy side, Update 9 also formalizes potions. The Berserk Potion injects flat Critical Rate and a large Critical Damage multiplier for fifteen minutes, while the Life Potion adds a 30% Max HP bonus for the same window. The two together are the bare minimum for a serious Castle attempt.
Companions are the third pillar. The Dragon's Grave is a wave-survival instance that is the only efficient path to Season 1 Battlepass currency, and the Wheel of Luck that the Battlepass funds is the only source of Companions like Earth Malls, Starfall, and the pinnacle Divine Dragonet.
