About this project
What does Just-In COMBAT add?

Weapon Parry & Block System
- Weapon Clashes (Parry): Striking an opponent while they attack triggers a clash. The outcome is calculated using the weapon's Damage, Resistance, and Attack Charge. Evenly matched strikes result in a mutual knockback, but if overpowered, the weaker side suffers a severe guard-break Stagger!
- Weapon Blocking & Stances: Hold right-click with a compatible weapon to block. If you block while crouching (sneaking), your weapon's resistance receives a 1.3x multiplier, making your stance significantly harder to break.
- True Attack Charge Weight: The attack cooldown meter now dictates your parry and block strength. Mindless spamming with an uncharged weapon will be effortlessly deflected by your enemies.
Revamped Shields & Guard Breaks
- Shield Deflection: Shields utilize a dedicated, high-defense formula. They easily deflect light attacks and inflict "rebound stagger" on the attacker. The stagger duration scales smoothly with the shield's resistance.
- Mobs utilize the exact same combat mechanics! Enemies equipped with shields will actively raise them based on distance and combat RNG.
- Guard Breaks & Cooldowns: Taking a massive hit (like a Greatsword jump crit) that exceeds your shield's defense limit will shatter your guard! Once guard-broken, the shield goes into a vanilla-style cooldown state, preventing both players and mobs from raising it again until the stagger ends.
Dynamic Jump Crits
Fully charged jump crits are no longer just flat damage boosts. Different weapon categories unleash distinct mid-air maneuvers:
damage_boost(Raw Power): Delivers a devastating damage multiplier, perfect for crushing enemy shields (e.g., Greatswords, Axes).stagger(Heavy Impact): Pierces through defenses to enforce a heavy stagger and knockback, acting as a strong crowd-control move (e.g., Hammers, Maces).dash(Evasive Strike): Transforms your aerial attack into a forward dash with brief invincibility frames, instantly closing the gap (e.g., Spears, Daggers).

I am working on these projects all by myself, so the update progress might be a bit slow. If you have the financial means and enjoy the mods I create, sponsoring me would give me more time to work on my mods without worrying about my income. Plus, you can leave a message in the sponsorship note about the content you'd like me to update!
This is really helpful for me.
