Notes & tactics

 * This perk is a potentially good pick in scenarios, when the player plans on relying more on weapons than on tower damage, but is also overall good as an extra damage boost.
 * It tends to shine more in Single Player mode than in coop, since in multiplayer enemies will also be killed by the partners, the chances of this being bigger if players are more. Additionally, the bigger health of enemies in coop makes for an increased likelihood of towers killing the lumes instead of the perk holder.
 * The perk finds use mainly in the Campaign & Easy modes, since in Survival it tends to lose impact over time, due to the increasing health of the enemies. Even with Concussion rounds, the last-hitting of lumes goes mainly to the towers.
