A lot of questions swirling around max heights. So I thought I would post my observations. Follow the footnotes for explanations of how I arrived at my numbers. DISCLAIMER: these are just my observations based on my castle building experience since the last publish and are not in anyway official. Don't get mad at me if you build this high and your items disappear. Ground level - or world height is counted as zero for the purposes of this discussion. (or 0 z where z is the vertical axis) Foundation - is 5 tiles high or 5z 1st floor - 6z height of the first floor* (you must raise a stone floor tile 20 times (i.e. 20 clicks of the decorator tool) to be level to the next floor) 2nd floor - 26z** 3rd floor - 46z 4th floor - 66z "5th floor" - 74z/75z*** The curious thing about the 75z max height is that if you subtract 5 for the foundation you get 70 which Kryonix(?) referenced as the highest you could build - so maybe he meant you can go a max of 70 up from your foundation? * this is based on the observation that a floor tile raised 5 times is the same height as short staircase (the kind you craft and the kind all houses use to enter a plot (customized or classic). The floor of any house is one tile higher than the staircase used to enter. ** this is based on counting the number of times I can raise a floor tile from the 1st floor until it's level with the next floor. ***5th floor is defined as the highest spot you can effectively "build" upon, where build is defined as the placing of any manufactured stone wall/stair/floor. In other words if you have a floor that's 74z high, you can add stone walls/floors, etc.). The term build does not seem apply to other items in the game. For example you can place a stone floor on the 5th level and then drop flowers, benches, chairs, etc without issue. but you cannot drop a stone wall. Yes you can raise floor tiles/gozas much higher but you can't build on them and based on various accounts the floor tiles seem to go *poof* at server up; other objects (e.g. flowers, chests, banners, etc.) remain. Interesting observation: if you are standing at 75z or higher and try to even take a stone floor/wall out of your pack you will immediately get the message "you may not build any higher". Similarly if you try and trade an crafted stone wall/floor to another player while you are 75z or higher, you will get the same message. This may explain why grass tiles stored or locked down above 75z have vanished - they simply cannot exist at that height unless you "cheat" and raise them with the decorating tool. DECORATING HINTS regarding height A manufactured stair case is 5 tiles high. You need a minimum of 3 rough stairs to be able to ascend to the next floor (assuming floor is 20 tiles high). This will require leaving uneven gaps between staircases. To make a smooth staircase you need 4 rough stairs. Each rough stair must be within 2z high of the next stair/floor in order to ascend the staircase. (i.e. a stair case if 5 high, if the next object is a max of 7 high you can climb it, but at 8 high you will be blocked). 16 - the number of times you must raise a floor tile before you can walk underneath it. If you stand on top of a ladder and drop a goza it's 17 high - but if you drop a stone tile or grass tile on this goza it will be 16 high. You can only raise a tile 15 times before you will get a message that you can't raise it any higher. At this point you will need to elevate yourself (higher floor, or ladder) to raise it any higher. These are my own observations - please post your own observations especially if they contradict anything I have stated.
