→0: Physical Accuracy Check: There is an enemy check on the Dex bonus that I didn't notice before. Physical Chance is unaffected.

=Damage Calculations=
<pre>If Attack Property "Always Critical" is Set
Set Critical Damage Flag
z = Actor's (M)Attack + ( x * y )
z = z * ( 512 - target's defense ) * Attack's Power
Damage = z >> 13/ 4096/This is a bit-shift left by 13 which is mathematically equivalent to dividing by 8192, but it's important to note that it doesn't actually divide as this is the source of the damage overflow glitch

<pre>
multiNoSplit = ( ( ( Attack's Target Flags AND Ch ) - 4 ) == 0 ? 1 : 0 )

=Accuracy Functions=
The point of these is to set the "attack will miss" flag in the current action memory structure.
===0: Physical Accuracy Check===''0x5DDBB0''<pre>;For the purposes of this code, "Dex" means the adjusted Dexterity of the actor/target if any in-battle dex bonuses have been granted.;Same holds for the Physical Evade. Physical Hit rate has no in-game bonus opportunities. Check_For_Cover() HitChance = -1; If "Always connect" flag set then HitChance = 255; If target has one of the following statuses (Death, Sleep, Confu, Stop, Petrify, Manipulate, Paralysis) then Remove Sleep status Remove Confu status Remove Manipulate status HitChance = 255End If If action is flagged as "always hit" then HitChance = 255; Physical Chance = (Actor's Dex >> 2) + action physical hit ratetodoIf Actor is enemy thenIt Actor's evade = Actor's Physical evadeelse Actor's evade = (Actor's Dex >> 2) + Actor's Physical evadeEnd IfIf Target is enemy then Target's evade = Target's Physical evadeElse Target's evade = (Target's Dex >> 2) + Target's Physical evadeEnd If If HitChance = -1 Then HitChance = Physical Chance + Actor's evade - Target's evade HitChance = FuryAdjust(HitChance)End If If HitChance = 0 then HitChance = 1 Luck Chance = [0..99]If (Actor's Luck / 4) > Luck Chance Then HitChance = 255 ;Lucky HitElse If Actor is Player Character targetting an enemy Then If (Target's long so Luck / 4) > Luck Chance HitChance = 0 ;Lucky Dodge End If End IfEnd If Miss Chance = (([0..65535] * 99) / 65535) + 1 ;essentially [1..100]if HitChance < Miss Chance then Set Miss flagEnd If</pre> ====Check_For_Cover==== This is where the game checks if the target is covered under a "cover"ing ally. It only applies to Player Characters It might be more complicated than I'll tackle it when I have a lot m seeing, but that is definitely ONE of time on my handsits functions ====FuryAdjust(HitChance)====<pre> If HitChance < 255 then If Actor is in Fury Status HitChance = HitChance - ((HitChance * 3) / 10) End If End If return HitChance </pre>
===1: Magical Accuracy Check===''0x5DDE5E''
<pre>
acc = Action's Accuracy
</pre>
===2: Critical Hit Check===''0x5DDF8E''
<pre>
If attack does not miss then
3, 4, and 5 don't exist. Since they don't set miss they will always hit.
===6: Manipulate Accuracy (intended solely for playable characters)===''0x5DE0D0''
<pre>
int ally_loop;
Manip_Chance = 255;
end if
if actor's <unknown> accessory property == 5 and //"Increase manip rate" property on Hypnocrown if Manip_Chance >= < 100 then Manip_Chance = 100; end if
end if
If Manip_Chance >= [0..99] then
ManipSuccess = 1;
end if
This doesn't actually place the target in the manipulate status. That happens elsewhere.
===7: Level-based Accuracy===''0x5DE08A''
<pre>
If Action's Accuracy > 0 then
