Reaction chain refunds 50% power spent to the other weapon. When using a mod equipped to a long gun, it behaves as expected, generating 50% of power spent to the handgun mod. When using a mod equipped to a handgun, it generates much less power than expected, something like 15% of power spent, to the long gun. The amulet seems to target a modswap playstyle but this currently keeps it from working well.
Repro: equip long gun and handgun with mods and no mutators, naked build (challenger for no locked points of spirit). Mods don't seem to matter, I suggest song of eafir and creeping mist because they both cost an even 1000 making it easy to gauge refund amount.
