This hack consists of two parts.
The first part makes weapons with 255 (0xFF) crit unable to crit. They will display – on the Equipment tab of the Inventory page and while using the R-button examine.
The second part modifies items with the Negate Criticals ability (0x80 in Weapon Ability 2) so that anything that is not an item with that effect only activates if equipped. For example, if you give an iron axe this ability, and Garcia has it in his inventory but is wielding a hand axe, the crit negation will not take effect. Likewise, if you trade that axe to someone who cannot wield axes, nothing will happen.
EDIT: I modified the check for the second part. Now, it first checks if the item has the first or second bits set (weapon or tome); if yes, then it checks if it’s equipped. Items that can’t be equipped get a free pass. Doesn’t really change much, unless you wanted a staff that negates crits.
This hack gives items 0xBC and 0xBD (can be changed in the EA file) the ability to modify their holder’s movement costs.
0xBC drops all traversable terrain costs to 1.
Example: Seth, a paladin, will now be able to cross forests with no movement penalty, but he will NOT be able to cross peak tiles, since he couldn’t do so normally.
0xBD makes the unit use the flying movement table.
Example: Seth will now be able to move as though he were a flying unit (obviously, terrain bonuses still apply (yes, this is ever-so-slightly OP)).
If both items are in the inventory, the first from the top will take effect.
NOTE: They don’t take into account weather conditions. If you absolutely want them to, contact me.
If you don’t want one or the other, change the item ID to one that isn’t used (0xFE or something). If you have a full item table and don’t know how to modify the .asm, contact your local wizard for instructions. It’s really easy, I promise.
