Range Spire

Gameplay Notes

 * The Range Spire is similar to the AMP Spire, in that it increases a certain quality of towers within its range. However, unlike the AMP Spire, this tower increases the range of other towers. The AMP Spire is also affected by it.
 * The effects of multiple Range Spires do not stack; only the highest effect is applied.
 * You cannot use a Range Spire to increase the range of another Range Spire.
 * Like the AMP Spire, the area of effect of the Range Spire increases with its rank. For ranks 1 and 2, this area is a 3x3 square around the spire. For level 3 Range Spires, the area of effect is a 5x5 square without the corner blocks (another way of stating this is "two straight blocks away, or one diagonal and one straight block away, but not two diagonal blocks away")
 * Gives 3.00% per every 100 overcharge.

Tower Strategies

 * Range Spire can increase the field of action of Slow Fields, and the blast radius of AR-Mines.
 * Using a Range Spire to increase the range of Focus towers can greatly increase its effectiveness, as the Focus will be able to keep firing at the target for longer, thus being able to damage enemies with its maximum potential for more time.
 * A ranged-boosted ACP can be used to dramatic effect, particularly behind other damage towers which require line of sight.
 * Increasing the range of a tower isn't always a good thing. Sometimes, you'll want it to focus on a certain spot, likely the killbox, so it doesn't waste time attacking enemies beyond that zone. Orbital Strike Relay (set to Most Health or Least Health) is the most notable example of this, as it should ideally fire on enemies which are slowed, stunned, or otherwise inhibited inside your killbox, not those that are rapidly traveling through the maze.
