New Systems Guide
Alpha
 7.10 came with upgradable downgradable blocks, land claims, friends 
list and locking doors and chests. Here is a little more information on 
how these systems work.
Upgradable and Downgradable blocks
Players
 can build wood frames and while holding a stone axe with wood planks in
 their inventory right click on a wood frame block and upgrade it to a 
wood block and repeat action to upgrade it to a reinforced wood block. 
Then if you have scrap metal you can upgrade it once again to metal 
reinforced wood block. These same blocks can be damaged and downgraded 
to their previous states and then repaired and upgraded again.
There 
is also a higher grade cobblestone path that upgrades form metal rebar 
to cobblestone to fortified to reinforced metal concrete
Land Claims
New
 players are awarded 1 land claim keystone block in their starting 
inventory if a server is running Survival PvP. Ways to earn more will be
 added in future updates.
You can kill players and loot their land 
claim blocks if they haven’t been placed or mine up a land claim block 
and steal it for your own so its wise to protect your land claim blocks
The
 keystone block is a special looking block that when carried by the 
player shows a 7?7 or server set protection grid rendered as a 
transparent green protected grid.
The keystone block offers durability protection 7?7 all the way vertically
Keystone blocks can be destroyed by other players removing their durability modifier of the fort
Only the owner and friends in your group can build blocks in your land claimed areas
Land
 claims have a no claim zone outside of their perimeter where only the 
land claim owner and friends in his group can stake additional 
neighboring claims. Default could be 30 meters measuring keystone to 
keystone (This could be an optional owner permission setting)
Only 
the owner of a land claim and friends in his group can add new 
neighboring land claims right next to an existing land claim but not 
overlapping
Zombies and owners/friends of the claim owner are not affected by claim durability
Players must revisit claim once a real-time day to prevent Claim Decay
Land Claim Game Options include
Claim Size – Sets the size of the protected area around a land claim block. Default is 7?7 all the way vertically.
Claim
 Deadzone – Sets the distance neighboring non friended players can place
 their land claims. Default is 30 blocks/meters away.
Claim Duration – The number of days a player can be offline before their land claims expire. Default is 3 real-time days
Claim
 Decay Mode – How a land claim’s hardness modifier decays over time that
 the claim owner is not on the server. Default is Slow
Claim Health 
Online – The hardness modifier applied to land claims for players who 
are currently online. Default is 32x harder to destroy.
Claim Health 
Offline – The hardness modifier applied to land claims for players who 
are currently offline. Default is 32x harder to destroy.
Friends list

 The new friends list can be found if click on the friends tab in the 
main inventory menu accessed by hitting ‘I’ in-game. From there you can 
invite players on the server to friend, see invites, accept invites and 
remove friends. Friends have advantages like sharing buildable areas, 
seeing each other player icons and turning on friendly fire if these 
options are set on the server.
Locking Doors and Chests

 Players who craft doors can lock them, unlock them and set passwords 
which can be shared with other players. Note the player who owns the 
door or chest never has to unlock it or enter a code to open the door. 
Friends who know the password only have to enter it once.
