Weapon Fusion

Hades II mod allowing you to fuse any* 2 weapons and their aspects. Takes Attacks and Specials from different weapons and combines them into a single weapon. Also supprts some AspectYoungMel aspects.

Gameplay examples of what it looks like in action:

• Xinth plus Persephone
• Moros plus Xinth

Installation

Use r2modman by ebkr from Thunderstore or GitHub.

It is recommended to backup your save from %USERPROFILE%\Saved Games\Hades II\Profile*.sav in case there are any unforeseen issues.

Usage

Salute the silver pool to fuse weapons. Fusion will only be possible once all weapons are unlocked.

Fusion can only be performed in the Crossroads training grounds.

If it feels like the fusion didn't apply properly try starting a run/reloading the room. If it still seems bugged would really appreciate a bug report :).

Same weapon fusion

There is also support for fusing two aspects of same weapon.

Note: During same weapon fusion, if any hidden aspect is fused as a primary it will override both the attack and special moveset.

Some minor limitations

• Aspect of Pan as primary does nothing when fused with any non-dagger aspect.
• Aspects of Medea, Eos and Moros don't have a Minor Aspect since they are heavily Attack oriented.
• Skull's Minor Aspect of Melinoe only affects Persephone and Medea (they're the only other ones with Ammo).
• Some weapons' attack/special will not produce Nyx's Nightspawn
