Guild Blueprints

Guild versions of siege blueprints can be produced by a Guild via the Scribe crafting discipline. Guild siege weapons are functionally the same as superior siege but have the supply cost of regular siege and display your guild tag and emblem (except guild siege golems, which are the same as alpha siege golems but have half the supply cost).

Crafting guild siege blueprints first requires a Guild Hall and the related upgrades in the War Room. A scribe with the required level can then craft Schematics which are automatically placed into the Aetheric assembly device to be queued for assembly. Once assembly is completed the blueprint can be accessed from the guild inventory panel.

Usage

Any player can place a siege weapon by using a blueprint from their inventory, which replaces their weapon skills with:

#	Skill			Description
1	Deploy Siege	1	0	Deploy your siege weapon
2	Cancel Build			Put your blueprint away

Using the deploy siege skill creates a build site at the target location. If the siege weapon cannot be placed at this location nothing will happen and the player will retain the blueprint bundle.

Allied players can then add supply by interacting with the build site. Once the build site is at full health it becomes an operational siege weapon. Enemy attacks can damage the build site before it is completed, increasing the supplies required.

Notes

• Blueprints used to be Account Bound, but this was changed in the July 9, 2013 patch, retroactively altering all blueprints in existence prior to the patch.
• Before the release of Heart of Thorns, Guild siege blueprints were purchased by guilds for Influence. Any blueprints owned by a guild prior to the update were transferred to the new guild inventory.

Bug:

Stacks of blueprints that existed prior to the patch will still function as account bound until the stack is updated. Acquiring new blueprints will automatically update an existing stack. You can emulate this by using a blueprint in WvW and then canceling deployment. If you have at least 2 items in the stack, you can force an update by splitting the stack and adding the old stack onto the new stack.
