Synergy

Overview

 * Enemies, that are damaged by you take 30% extra damage from towers for 4.5 seconds.
 * Stacks if multiple players with the perk attack a target.
 * Stacks multiplicatively with Amp Spires.

Notes & tactics

 * It is a potentially good pick when the player has a good plan on using a strong killzone with towers, that potentially can kill or damage highly all attacked lumes.
 * In coop it tends to shine some more than in solo mode, since the investments into towers are more and towers become more likely to do more damage than weapons. Also if multiple players take this perk, this can easily lead to a very high tower damage.
 * While potentially powerful, it is often behind:
 * Tinkerer, since it is more likely to damage enemies for more, without the need of attacking them all at once. Most maps can easily be played with a base structure of Focus + ACP + Drone/Anti-air + Range spire.
 * Exposure rounds - this is mostly valid for the Campaign & Easy modes, where the early game might often play a very big role and Synergy has more issues finding good use, particularly if not being able to hit all lumes that pass through the damage of the towers.
 * This perk finds good use in all game modes, including Survival, where it appears to be among the best possible perks to have.
