Check your roles before retrying
A boss attempt usually fails faster when every card solves the same job. Cover recovery, protection, damage, and setup before you decide the deck is ready.
How to Beat Arg'il in Block Tales
Start this Arg'il prep by checking survival, SP room, damage plan, and whether your cards fit the fight before spending more attempts.
Use live-game behavior over old advice
Block Tales boss advice can change after updates or fresh player runs. If a guide conflicts with the live fight, trust what happens in-game and adjust the build.
Turn the fight into a build
Open the build maker when you know what keeps ending the run. A usable plan shows BP left, SP pressure, survival coverage, and cards to try next.
Chief of the Korbloxian Empire, not just a knight
Arg'il is the chief of the Korblox Empire and the direct enemy of all three guilds of Trinity. The fight is the second half of the Demo 5 Chapter 5 double-boss gauntlet: Frostmaw is the corrupted earth-mage co-final boss, and Arg'il transforms into a massive Korblox Dragon once the fight shifts to his true form.
Dragon caps at 7 damage per hit under Shield
Community tests show the Korblox Dragon cannot take more than 7 damage per hit while the Shield stat is up. Items bypass Shield entirely, so item-driven damage (Bombs, Thorns-toss items, Slingshot bursts) is the way through the shield phase. Card-only raw damage will be wasted on every shielded turn.
Feel Fine and similar buffs do not touch Cassie
Some player cards that heal or buff the party do not register on Windforce Cassie during the Arg'il / Dragon phase. Do not build a run around self-buff stacking that requires Cassie to receive the effect — she will not pick them up, and your support slots will be silent.
Item damage, one self-heal, one peel
A reliable Arg'il / Korblox Dragon run uses item-driven damage (to bypass the 7-damage Shield ceiling), one self-heal card (for the Dragon's melee bites and tail sweeps), and one peel or shield card (to keep Cassie alive through the second wind). Use the build maker to confirm BP, SP, and item-damage coverage before entering the Seventh Sanctum.
