3-7 Roar Mission - Tips To Win

Set The Roadblocks Immediately

3-7 Roar Mission Roadblock Placement
Click to Enlarge

While you can place 8 Roadblocks, you only need 3 to divert the enemy lanes. Place the 3 Roadblocks after setting a Vanguard.

Deploy AoE Attackers

Deploy AoE Attackers

As you will be using Roadblocks to diver the flow of enemy waves, you can make use of AoE damagers to easily deal with the enemy mobs.

No Need To Use The Detector

No need to use the detector

As you can control the pathing of enemy waves, there is no need to use the Detector to hit stealth units. You can simply use Defenders and wait for these invisible units to come, then hit them with ranged Operators.

Deal With The Mortar Gunner

The lower right enemy camp will spawn a Mortar Gunner, a long-range high ATK enemy unit. Leaving it as is can devastate your defenses, so bring a low-cost Operator and set it directly on the Mortar Gunner's tile to stop its attack.

Bring Reserve Casters

Bring reserve casters

The latter waves will spawn Heavy Defender Leaders, units that have exceptional HP and DEF but mediocre RES. Bring spare Casters to deal with this late-game threat should your usual lineup be insufficient.
