Spire Upgrades

Upgrade during Build Phase or at start of your Onslaught Turn using a Limited Build Option. Spend Source to add Upgrades up to Upgrade Capacity unless instructed otherwise. Spire can exceed capacity via certain effects, but you cannot choose to exceed unless instructed. Costs: each Range/Attack Upgrade costs Source equal to the number of Upgrades on the Spire including the one being added; each Fortification Upgrade costs 2 Source. New Upgrades go to bottom; removed from bottom. Spires and units use same upgrade chips but function differently. See also: Upgrade Capacity
