Calldowns

The calldowns for Abathur, at level 15, with no mastery points added are:

Calldown Name Description Recommended Usage Numbers
Drakken Laser Drill Attack Drakken Laser Drill Attack Attack with the Drakken Laser Drill. Deals 20 damage per second and has unlimited range.
  • Auto-targets enemy units in vision.

Masteries

Below are the three Power Sets for Swann with the recommended point allocations for each. Note that these are meant to serve a general, all-purpose build that is effective across all maps. You are highly encourged to change these masteries to suit your playstyle and particular challenges you face (e.g. Weekly Mutations).

Power Set 1:

Power Value Recommended Points to Add Further Considerations
Concentrated Beam Width and Damage 2% per point
60% maximum
19 Players that prefer to rely on their Combat Drops to tank for their main army should consider adding more points into that respective mastery. The Combat Drops can severely reduce the amount of damage their army takes.
Combat Drop Duration and Life 2% per point
60% maximum
11

The 19 points into the Concentrated Beam mastery ensures you can 1-shot Battlecruisers with the ability.

Power Set 2:

Power Value Recommended Points to Add Further Considerations
Immortality Protocol Cost and Build Time -2% per point
-60% maximum
? Immortality Protocol can be critical to ensuring Swann is able to keep up with the eventual losses his army will take as the game progresses. However, it only applies to certain units, and it is important for a player to determine whether they will benefit from Immortality Protocol more than they will benefit from increased structure health.
Structure Health 2% per point
60% maximum
?

This is down to player preference. If you tend to rely more on Siege Tanks and Thors, then the Immortality Protocol mastery should be chosen, otherwise, the Structure Health is a better option, especially when relying on static defenses.

Power Set 3:

Power Value Recommended Points to Add Further Considerations
Vespene Drone Cost -3% per point
-90% maximum
? Early Vespene Harvesters can provide Swann with the much-needed gas that he needs to get some of his higher-tech units out earlier. However, the Laser Drill mastery will allow the player to have a much more global presence on the map, allowing them to tech up to their end-game build without the constant harrassment of attack waves. It is up to the player to determine which mastery/what ratio of mastery points to allocate for this.
Laser Drill Build Time, Upgrade Time, and Upgrade Cost -1.5% per point
-45% maximum
?

The regular choice is the Vespene Drone Cost mastery. However, for more mineral-heavy builds, and builds that rely on the Laser Drill, the Laser Drill mastery is the preferred choice.

Gameplay Guide

Playstyle Traps

A common trap for Swann players is to try and rush Thors out in the early game. Not only does it leave them extremely vulnerable to the early game, mass Thors can only work when actually massed in large numbers.

A much better build would be to start with Goliaths backed up with Siege Tanks and then transitioning to Thors as the economy improves.

Drakken Laser Drill Levels

The below table summarizes the Levels available for the Drakken Laser Drill.

Level Drill DPS Unlocked Abilities Minerals/Gas Research Time
1 20 None - -
2 30 Concentrated Beam 200/200 190 seconds
3 50 Pulse Cannon 300/300 220 seconds

Static Defense

Swann has a few of static defense structures available to him. These are shown below:

Building Name Stats
Flaming Betty Flaming Betty HP: 350
Attack: 16
(vs Light): 20
Range: 4
Speed: 1
Targets: Ground
Spinning Dizzy Spinning Dizzy Detector
HP: 325
Damage: 12 / 1
Attacks: 2 /8
Range: 7 /7

Targets: Air / Air
Blaster Billy Blaster Billy HP: 300

Targets: Ground

Swann has upgrades that can improve his static defense. The upgrades are listed below:

Upgrade Name Effect Minerals/Gas Research Time
Hi-Sec Auto Tracking Hi-Sec Auto Tracking Adds +1 range to all Turrets. 100/100 60 seconds
Structure Armor Structure Armor Upgrades the armor of structures by 2. 100/100 60 seconds
Fire Suppression Systems Fire Suppression Systems All structure fires are automatically extinguished and all structures automatically repair themselves to 50% of their maximum life at a rate of 15HP/second. 100/100 60 seconds
KMC Auto-Loaders KMC Auto-Loaders Increases the attack speed of all Turrets by 25%. 150/150 90 seconds

The Drill on Dead of Night

The Drill should be used by Swann to clear infested structures on Dead of Night. Clearing defenders with the Concentrated Beam or Pulse Cannon is just an added bonus. The images below show suggested uses for both, the Concentrated Beam and the Pulse Cannon. Note that the Concentrated Beam here has the bare minimum number of mastery points added to 1-shot infested structures (13 points). You will get better results if you have more mastery points added (for example, if you follow this guide and allocate 19 points).

Also, notice the difference in Concentrated Beam Locations depending on the player. Because the beam exits your Laser Drill, the positioning is different depending on which player you are. Unfortunately, Player 2's Concentrated Beams are significantly less efficiently, purely due to the layout of the infested structures relative to the drill.
