Vortex Gaming

· Challenging the new hidden boss, Mathias, under full restriction conditions.
· Mathias has 88,000 HP plus an additional 50,000 HP and is highly vulnerable to most elemental attacks.
· High attack power and the 'Glass Cannon' effect can inflict significant damage from the start.
· A suboptimal character placement (Don Quixote) required an early strategy adjustment.
· The sanity restriction (below 30) made the battle even more difficult.

· Initially surprised by Mathias's unexpectedly high attack power, the team sought to revise their strategy.
· The existing approach was modified by adjusting the number of characters and trying new team compositions.
· Explored ways to utilize the abilities of Healthred and Gebura through multiple attempts.
· Faced difficulties in defeating the boss for over an hour, including a crashing bug that occurred mid-battle.

· Developed an optimal strategy to clear Mathias in just 3 turns.
· On the first turn, activate Healthred's Moody Blues ability and carefully select skills.
· Coin-flipping is focused on Ice and Fevnir, with the fastest speed dice belonging to the "Impending Release" skill.
· In the "Impending Release" deck, Fevnir deals high damage, so prioritize and preserve Fevnir's clashes.
· Sacrifice Ice and utilize two of Kether's skills to gain an advantage in speed dice battles.
· Use 3-star Healthred to draw out Mathias's and Kether's counter-attacks.
· Direct the remaining skills towards the sacrifice, block one of Mathias's attacks on Fevnir with the sacrifice, and receive the other with Fevnir.
· Yang is attacked by Kether, taking damage.
· Utilize the "Charge Speed" effect to aim for defense reduction.

· The sacrificed character played an excellent role.
· Used Ice's Auto-Unshin to gain an advantage in the battle.
· Fevnir and Yang attack, and when Fevnir loses their clothes, immediately take them to bed and counter-attack.
· The next turn, grant Gebura's ability to Yang to increase survivability.
· Create the best situation where two of Mathias's skills target Yang.
· Unsure about Fevnir and Yak Sang, continue the attack with Mathias 1.4.
· Kalpas clashes with Mathias to finish him off.

· Contrary to expectations, not only Kether but all characters received a significant boost against Mathias.
· Use all remaining skills to secure a kill shot on Mathias, who has about 40,000 HP remaining.
· Successfully clear Mathias and achieve victory.
· This clear was possible thanks to Yang's strength.
· Fighting high-floor bosses is very fun, and I recommend trying it with different decks.

· The next video will introduce a powerful "Impending Release" deck.
· If you're struggling with the Floor 15 boss, I strongly recommend trying it, even if not under full restrictions.
· Fighting Mathias was a very fun and challenging experience.
