v2.2.4

Release Date

Dragon Cannon release and ammo polish: the Skyburn Dragon Cannon now drops from the Dragon Lord at 1%; all 15 compatible ammo profiles received behavior, visual, and performance polish.
Zombie Mode special-enemy improvements: Exploder, Plague, and Harasser behavior now matches their telegraphs, hits, and area effects.
Reverse Scale compatibility fix: fixed Reverse Scale sometimes failing to trigger after the latest damage-event timing changes; it now grants a brief invincibility window after activation.

The Dragon Cannon now has a 1% drop rate from the Skyburner Dragon Lord. The transferred 4% raises Reverse Scale's drop rate to 39%.
All 15 compatible ammo types can be selected in the ammo-type list. Each one rewrites the cannon's damage, fire rate, magazine, range, and projectile behavior.
Polished the special behavior of Rocket, Shotgun, Arrow, Energy, Snow, Nano, Candy, IceBlade, and Firework ammo.
Optimized Firework split scheduling, hit-effect pooling, and warmup. Its visual and damage design are preserved while impact-related frame drops are substantially reduced.

Exploders now only detonate near the player; their telegraph and blast follow their current position, and they self-destruct after exploding instead of repeatedly chasing and detonating.
Plague enemies and related elite affixes now create persistent poison clouds. Harassers now fire projectiles that create a slow zone only after impact.
Fixed slow zones affecting players outside their radius and corrosive areas lacking a warning delay before their first damage tick.

Reverse Scale now preserves its trigger window before lethal damage can enter the original death flow.
After healing, Reverse Scale grants a 0.5s invincibility window to reduce instant follow-up deaths.
