Final Fantasy X Walkthrough
Yojimbo and Zanmoto

Thanks to The Supreme Alien from the Gaming Forum for compiling this information!

woohoo at last you too can now see if you have a good chance of
pulling off Zanmoto on those big nasty people!!!!
Its all about motivation and there's 5 ways to rack up motivation points!!!
Factor 1 Amount of Gil
this ones quite simple
gil-motivation
4 - 2
8 - 4
16 - 6
32 - 8
see the patern each time you double the gil your motivation goes up by 2
say we gave him 100000 Motivation would be 30
Factor 2 Compatability
stat starts at 50pts max at 255pts
list below effects compatibility
PAY 0 gil -20pts
Yojimbo Dies -10pts
Dismiss without paying -3pts
Uses daigoro -1pt
Uses Kozuka No Change
Uses Wakizashi(single) +1pt
Uses Wakizashi(All) +3pts
Uses Zanmoto +4
The motivation is then worked out by
Compatibility pts/30 = motivation
eg c=255/30 = 8.5
Factor 3 Zanmoto Level
c=motivation from compatilbility g=gil paid t=total gil you have
c * (0.75 + [{p * 0.5} / t])
eg we'll use c=8.5(from result above) pay him 100000 from 500000 we have in total gil
8.5*(0.75+[{100000*0.5}/500000])
8.5*(0.75+(50000/500000)
8.5*(0.75+0.1)
8.5*0.85=7.225
7.225
this number then gets used thus, when you first attained Yojimbo and
answered wanted to hire him by saying "help with your training as a summoner"
or "help to destroy fiends"
then
for all bosses(zanmoto lv4) except All Monster Arena bosses,
Dark Aeons, and Penance *0.25(these are zanmoto lv5)
for lv5 *0.2
for Adamantoise Anima(Zanmoto Lv3) *0.33
for Barbatos, Behemoth, Behemoth King, Cactuar, Qactuar(Zanmoto Lv2)*0.5
for all others(Zanmoto Lv1) *1
However if you chose to destoy the powerful enemy's option then for Zanmoto lv1-lv3 *0.8
and for zanmoto lv4-lv5 *0.4
exp I choose poweful enemy's one and I'm fighting a Dark Aeon(Zanmoto Lv5)
using the number above(7.225) I times* 7.225 by 0.4 which = 2.89(this is part of the motivation lv)
Factor 4 Overdrive
This is simple if he's in overdrive you get 2 motivation pts
lets say he's in overdrive for this example
Factor 5 Randomality
(didn't you just know it)
it randomly selects a number from 0-63
for this example lets say 45
ok now lets see what kind of attack would have been performed
Motivation Lv - Attack
0 - 31 would give Daigoro
32 - 47 would give Kozuka
48 - 63 would give Wakizashi(single)
64 - 79 would give Wazikashi (All)
80 + would give ZANMOTO
so we got*drumroll*
Factor 1 =30
Factor 2 =8.5
Factor 3 =2.89
Factor 4 =2
Factor 5 =45
Total No.=88.39
Result Zanmoto Performed Woohoo!!!!!
