· The 10th Angel Descends stage, the second super-high difficulty stage in the Evangelion collaboration, consists of two tiers: Advanced and Super-Extreme.
· The Advanced stage is designed for beginners to obtain Lil' Kaworu 3rd form, with a 5% drop rate (100% with Treasure Radar) and a difficulty of ★2.
· However, despite being ★2 difficulty, the boss's stats are very high; it's rare to find an enemy in other ★2 stages that requires 4 hits from Bahamut Cat to defeat.
· In the Super-Extreme stage, you fight the 10th Angel at 100% magnification, which has an area attack, detection range of 400, max range of 900, and min range of -3600.
· Its attack power is 150,000, instantly killing or critically wounding most characters, and it possesses Wave Immunity and immunity to 4 types of debuffs.
· Enemies that can attack within their detection range without a safe zone in front tend to be powerful, and the 10th Angel can attack up to +500 behind itself with high attack power, making it a formidable collaboration boss.

· Seven years after the 10th Angel's implementation, various allied characters have emerged, and among them, Ultra Stone Cat stands out as an effective attacker.
· Ultra Stone Cat was implemented in November 2025, so it couldn't be used in the previous collaboration, but it shines in this re-collaboration.
· Upon 4th evolution, it gains HP, movement speed, area attack, and the 'Survive' ability, becoming a mass-producible attacker with 'Survive' like Cameraman Cat or Manic Macho Leg Cat.
· Especially thanks to the 'Survive' ability, it can withstand the 10th Angel's 150,000 attack once, significantly increasing its damage efficiency against the 10th Angel and for clearing weaker enemies.
· Increased movement speed makes it easier to approach the 10th Angel's feet, improving attack accuracy, and it quickly detects enemies deep within, which is advantageous for clearing weaker enemies.
· It possesses 'Massive Damage' against Black and Angel enemies, allowing it to instantly defeat Master A. and Angel Gabriel, which was impossible with the 1st form Stone Cat.

· With the synergy of 'Survive' ability, increased movement speed, and attack power up, Ultra Stone Cat performs both wall and attacker roles simultaneously.
· Weaker enemies are also cleared smoothly, allowing victory by continuously deploying only Stone Cat without other wall or attacker units.
· Since only Stone Cat needs to be spammed, auto-play with Cat CPU is possible, enabling the defeat of the 10th Angel.
· However, with only Stone Cat, it takes a long time to chip away at the 10th Angel, making it difficult to collect scoring rewards (XP, Sniper Cat).

· A strategy utilizing Hellfire Dojima Cat is also possible.
· Against the 10th Angel's 150,000 attack power, a Lv.60 Hellfire Dojima Cat (before True Form) has 149,760 HP, barely getting instantly killed, making attack power up impossible.
· However, a Lv.61 Hellfire Dojima Cat has 150,930 HP, allowing it to survive one hit, making it an 'essential' character.
· For Lv.60 or below, forming an HP combo to allow it to survive one hit can trap the 10th Angel in a knockback loop.
· Hellfire Dojima Cat does not have the 'Angel Killer' ability, but it effectively defeats the 10th Angel with attack power as if it did.

· The 10th Angel Descends stage is prepared up to Stage 3, where all enemies are further strengthened by 3 times.
· The boss, 10th Angel, is also strengthened by 3 times, applying a 300% magnification, resulting in 7,500,000 HP and 450,000 attack power.
· Ultra Stone Cat, which was instantly killed in Stage 1, can still survive one hit thanks to its 'Survive' ability even with 3 times the attack power, but the HP to chip away increases from 2,500,000 to 7,500,000, extending the clear time.
· The biggest problem is the strengthening of weaker enemies. Master A., Angel Gabriel, Zombie Doge, Red EnerG, and Gory are strengthened, drastically increasing the difficulty of clearing weaker enemies.
· In particular, Gory has 180,000 HP and requires 12 hits to defeat, so if weaker enemy clearing is delayed, the 10th Angel might detect the Cat Base, leading to defeat.

· While Stage 1 could be cleared with only Ultra Stone Cat, Stage 3 requires adding Zombie Cat as a wall due to the difficulty of clearing weaker enemies.
· Zombie Cat possesses a 100% 'Survive' ability, allowing it to withstand one attack from the 10th Angel, and performs optimally as a wall against bosses with insane attack power and ultra-long range.
· Zombie Cat also has surprisingly high attack power with 3,600 DPS, allowing it to attack the 10th Angel, and it can be produced twice as fast as Stone Cat, dealing sufficient damage.
· It acts as a wall against rushing weaker enemies, suppressing the advance of the 10th Angel and weaker enemies, and assisting Stone Cat (with 1 HP remaining) from being attacked.
· Equipping Zombie Cat with an 'Attack Nullification Orb' allows it to activate attack nullification with a certain probability regardless of attribute or special enemy, enabling it to withstand the Angel without taking damage.

· The Stage 3 is cleared with a combination of Zombie Cat and Ultra Stone Cat.
· During the battle, multiple Zombie Cats can be seen with 'Attack Nullification' effects, withstanding hits without being knocked back.
· The 10th Angel is knocked back every time it takes 1,500,000 damage, so after 4 knockbacks, it has taken 6,000,000 damage.
· If weaker enemy clearing is delayed, the 10th Angel might detect the Cat Base, leading to defeat, so smoothly dealing with Gory, the strongest weaker enemy, is especially important.
· While auto-play with Cat CPU makes the game more difficult, manually firing the Cat Cannon can increase the win rate.
· Ultimately, the 10th Angel was successfully defeated, taking approximately 4 minutes and 30 seconds with 3x speed. The score is 0 points.
