Coop TD: Together Attack Speed and Damage Upgrade Guide

To maximize Damage Per Second (DPS) in Coop TD: Together, invest in Attack Speed during early waves to handle dense groups of low-health enemies, then shift gold investment into raw Damage in mid-game waves when enemy health pools rise. Attack Speed and Damage function multiplicatively, meaning neither stat should be completely ignored during a match.

Stat Upgrade Timeline by Stage

Managing stat upgrades requires adjusting priorities as wave compositions change. Early waves demand rapid firing to clear large crowds, while later waves require raw damage to breach high enemy health pools.

How Attack Speed and Damage Interact

Attack Speed acts as a direct multiplier for flat damage bonuses by reducing the firing interval and animation downtime between attacks. This interaction creates specific strengths and failure points depending on how stats are distributed:

• High Damage with Low Speed: Towers deal heavy single-target hits but risk wasting long animation cycles, allowing fast or numerous enemies to pass through ranges unchecked ("slow cannon" effect).
• High Speed with Low Damage: Towers fire rapidly but produce insufficient damage per shot, failing to diminish large health pools before enemies reach the exit ("tickle damage" effect).
• Flat vs. Percentage Buffs: Flat stat additions provide an early baseline, while percentage increases yield higher returns once base stat values are higher. Percentage attack speed buffs offer maximum value when applied to towers with naturally high base damage ceilings.

Diagnosing Stat Bottlenecks

Watch board performance closely to identify which stat upgrade your defense requires:

1. If enemies reach the track exit while towers are stuck mid-animation, upgrade Attack Speed.
2. If towers hit targets repeatedly but fail to reduce enemy health bars significantly, shift gold to Damage.

Support Tower Positioning for Stat Synergy

Rather than spending gold to upgrade attack speed individually across every primary damage dealer, use dedicated support towers to provide attack speed buffs.

1. Identify Intersections: Place support towers at path intersections where their aura ranges cover multiple main attackers.
2. Specialize Primary Attackers: Allow primary damage towers to allocate incoming gold exclusively toward Damage upgrades while receiving passive speed from support units.
3. Match Tower Profiles: Align upgrades with inherent unit roles. Ensure rapid-fire support towers reach target speed thresholds to trigger secondary effects like critical strikes or damage-over-time debuffs effectively.
