It is an additional option for a trapped character to have a chance to still get out of the trap.
If someone receives PvP damage, the server checks whether this character can move to at least one of the squares around him. If this is not the case, all characters standing on one of those squares are marked for him with a beige square around him. Now, the trapped character can walk either by cursor or by mouseclick on any of these fields and will thereby switch positions with that character.
Exceptions:
- If the trapped character was aggressive against one of those blockers (he attacked first so got a yellow or white skull for it), he cannot swap with that character for 60 seconds since the last damage.
- If this character has already swapped with the other character, they have to wait 5 seconds to swap again with each other. They can however continue to swap with other trappers.
Delays:
- We will start with a standard delay of 1 second on a swap (plus the usual walking speed delay when you walk).
Other things:
- If one of the fields is blocked by a stack of characters, the top character is the one that counts. If the target is allowed to swap with him, that top character will be pulled onto the targets field and the target will enter the stack all the way down.
- If the target stands on a fire field, he can still swap, so yes, he will pull his trapper onto that field.
