Combat roles reworked and snake ban order

• Terran infantry trade early durability for a research choice: boost firepower or convert to heavy armor.
• Science Vessel, Raven, Defiler, and Tyrannozor gain new tactical options or dedicated researches.
• The ban phase gains a snake order, and essential detection and transport units are no longer bannable.

Terran

• Fixed attack and armor upgrades not applying to some extension units, including the Goliath.
• Fixed the cast range indicator of Defensive Matrix. The ability is a point-targeted effect, and the cast cursor now references the actual area effect.

Zerg

• Fixed the Ravager's Corrosive Bile button not showing.
• Fixed the Infestor's ability buttons and hotkeys overlapping.
• Fixed Larva hotkeys overlapping when a replacement production button is exposed by a ban.
• Fixed the Tyrannozor attack animation, the Defiler Mound under-construction actor, and the actor swap for spent creep.
• Fixed the Queen keeping her on-creep movement speed when off creep.

Protoss and General

• Fixed the Protoss air attack and armor upgrade buttons, and the production buttons of the Robotics Facility and Gateway not showing.
• Cleaned up some tooltips and lobby option displays.
• Fixed the timer not resetting after the draft ends. The round-end function now sets the remaining time to 0 and disables the timer trigger.

Known Issues

• The Energizer model does not swap correctly when it changes to phase mode. It has no effect on gameplay and will be fixed in a later update.
• Because of limits in the campaign dependency data, the production resource display of some units cannot read the real requirement. Those tooltips may show white text regardless of whether the unit can be produced.

Terran

Marauder and Firebat

• Marauder: Health 125 → 100, armor type Armored → Light. (From PatchesSC)
• Added Shatter Shells: researched at the Barracks Tech Lab for 100/100 and 79s. Requires the Concussive Shells research and a Ghost Academy. Marauder concussive shells slow enemies within a radius of 1.5.
• Firebat: Health 100 → 75, armor type Armored → Light.
• Added Napalm Canister: researched at the Barracks Tech Lab for 100/100 and 79s. Grants +5 damage against Light targets, +2 attack range, and a shorter attack delay.
• Added Infantry Heavy Armor research: researched at the Barracks Tech Lab for 150/150 and 79s. Raises the Firebat's and Marauder's health by 25 and converts them to Armored.

They are weaker than before in the early game, but later you can choose to boost firepower with ammo research or reinforce the front line with heavy armor.

Mechanical and Air Units

• Added Crucio Suppressor to the Siege Tank. Researched at the Factory Tech Lab after you have an Armory, for 100/100 and 79s. It reduces friendly splash damage in Sieged Mode by 75%. (From PatchesSC)
• The War Hound's Haywire Missile now deals bonus damage to Armored targets as well as Mechanical ones. Bonus damage is 30 → 20, and research cost and time are 100/100/110s → 150/150/79s.
• Increased the Goliath's ground attack damage.
• Removed the Raven's Interference Matrix and adjusted Repair Drone and Auto-Turret.
• Added Integrated Fire Control Network to the Raven. Researched at the Starport Tech Lab for 150/150 and 79s, and uses 50 energy. It deploys a network at the target point that automatically marks one enemy within range, and the marked target takes 20% more damage. The mark is removed when the target moves 2 or more beyond the network's range. The effect does not check armor type.

Science Vessel

• Irradiate: Energy cost 25 → 75, and the splash damage range the affected unit deals is reduced.
• Defensive Matrix: Energy cost 100 → 50, radius 1.5 → 1.75, absorb amount 16 → 24.
• Added Science Vessel Boost: researched at the Starport Tech Lab for 100/100 and 100s. When used, movement speed is 2x for 6 seconds, with a 14 second cooldown.

Irradiate's area pressure is lowered, and the Matrix and mobility research strengthen the options of the Science Vessel as a support unit.

Zerg

Ground Units

• Aberration: Health 275 → 200, damage 20 (+20 vs Armored) → 15 (+15 vs Armored, +1 per upgrade), range 1.25 → 1.75, supply 3 → 2.
• Ravager: Morph time 12.14s → 8.57s, total supply 3 → 2, morph cost 25/75 → 50/50, health 120 → 150, Corrosive Bile cooldown 7.14s → 6.5s.
• Ravasaur: Armor type Armored → Light, damage 10 (+15 vs Armored) → 10 (+10 vs Armored, +2 per upgrade).
• Defiler: Added an attack and adjusted production cost and time from 50/150/40s → 50/200/34s.
• Dark Swarm: Instead of immunity to all damage, it now reduces ranged damage by 50% and melee damage by 30%. The effect data searches only friendly and allied units.
• Viper: Removed its air attack. It now attacks ground only.

Air Units and Hero Units

• Guardian: Health 150 → 200, movement speed 1.97 → 2.2.
• Added Parasite to the Queen (75 energy). It reveals the target's vision, and infected units show a green cloud and a red outline.
• Added area damage and 20% life steal of damage dealt to the Tyrannozor.
• Added the Tyrannozor-only Primal Molt Evolution: researched at the Ultralisk Cavern for 150/150 and 90s, and grants +1 armor. It is shown only when both the Tyrannozor pick and a completed Ultralisk Cavern are confirmed.

Protoss

• No direct number changes. Fixed the display problems of buttons and units for air upgrades and production buildings.

• Added the Snake Ban option. With 3 bans, the order is 1 → 2 → 2 → 1 → 1 → 2.
• In Convenience Mode, the Alt key toggles the ban info HUD and the production window together. Key input is handled per player.
• Improved the game to hide the dedicated upgrades of unpicked units. Whether an upgrade is allowed is updated based on whether the unit is active for the player.
• Observer, Medivac, and Warp Prism are excluded from the ban pool, so that detection, transport, and power-network functions are not removed entirely by bans.
