Few Questions

but for the presence of a specific relic by index number.

wait a moment... say you change tintinnabar into a sword... will the effect still connect? i mean... you said "of a specific relic"

Yes. Here is the code. It was in C0, not C1 as I thought.

Code:

C0/4A6C:    B92316      LDA $1623,Y        (Load character's relic 1)
C0/4A6F:    C9E5        CMP #$E5        (Is it Tintinabar?)
C0/4A71:    F007        BEQ $4A7A        (Branch if it is)
C0/4A73:    B92416      LDA $1624,Y        (Load character's relic 2)
C0/4A76:    C9E5        CMP #$E5        (Is it Tintinabar?)
C0/4A78:    D019        BNE $4A93        (Branch if it's not)
C0/4A7A:    20E8AE      JSR $AEE8
C0/4A7D:    B91C16      LDA $161C,Y        (Load character's stamina)
C0/4A80:    4A          LSR A            (/ 2)
C0/4A81:    4A          LSR A            (Now / 4)
C0/4A82:    C221        REP #$21
C0/4A84:    790916      ADC $1609,Y        (Add current HP to Stamina / 4)
C0/4A87:    C51E        CMP $1E
C0/4A89:    9002        BCC $4A8D
C0/4A8B:    A51E        LDA $1E
C0/4A8D:    990916      STA $1609,Y        (Store to current HP)
C0/4A90:    7B          TDC
C0/4A91:    E220        SEP #$20       (8 bit accum./memory)

Basically, it says: Check relic slots 1 & 2 for the presence of item number "E5" (decimal = 229). If that's the equipped item, do the Tintinabar effect.

So, if you were to have item E5 equipped to the weapon slot, it would never get checked for the Tintinabar effect. This is changed by the "Unhardcoded Tintinabar" patch to check the characters bitfield rather than their equipment slots.
