Be sure to take notes of all the relevant names and IDs as you go. Make lots of backups.

Be careful not to use any duplicate flags or Entity IDs; regions with duplicate EntityIDs in particular have a chance to permanently corrupt loaded mapbnds, so exercise caution.

Be careful when making Flag IDs; if the fifth digit is 1-9, it will cause the flag to reset on grace/area reload (Eg: XXXX0XXX).

Refer to other Entity or Flag IDs to see how FromSoft formatted them; sometimes it might matter, or not.

If you're curious about most entities having MapID: -1, UnkE0C: 255, and UnkS0C: -1, don't ask me. I have no idea, but changing it can break things. So just keep them that way.

1. Create a new ladder asset, and give it a unique EntityID.

2. In the map EMEVD file, add a new RegisterLadder event.

$Event(eventID, Default, function() {
    RegisterLadder(disableTopEventFlagId, disableBottomEventFlagId, entityId)
});

FlagIDs should be eight-digit unused values, fifth digit 0

3. Initialize the new event by adding a line to Event(0, at the top of the page.

    InitializeEvent(0, eventID, 0);

4. Done. It's that easy.
