The upgrade also affects structure shields doesn't it? Could be useful if you've got a proxy or choke or dangerous expo... or some weird cannon thing going on.. lol

A lot of special situations benefit well from shields upgrades. For example hit and run heavy play with a lot of extra minerals (mass air maybe).

You will need to dump minerals in cannons and zealots and your main stuff is air. Cannons, zealots and air all benefit from shields so it might be cool especially since you only stay as long as you have shields with the air before you pull away for a long time

from the lp article

One interesting detail: when an attack depletes a shield and starts removing hit points, both the shield armor and standard armor damage reductions are applied.

Actually if you are not doing allins with ur army then in my opinion shield upgrades are better than armor(mid-late game only ofc), especially for key units like colossus, because u micro them to not let them die as u see that their shields are nearly depleted or hp goes down. For that reason shield upgrade applies multiple times, as long as u save ur units from dying - their shield regens and dmg reduction applies for another battle for full shield value, while hp doesn't regen thus its upgrade applies only once for each point of life. Although most units have more hp than shields I think that it's definitely worth getting up to +2, after +1 weps and armor, unless u expect emp play. It's also very good against z because protoss units are so much stronger than zerg and for that reason u will usually save most of them with small hp loss if microed correctly and engaging in chokes.

The main thing to consider is how much damage is going to be dealt to both your shields and armor. For the most part, it's safe to say that the shield will take more damage because of regeneration. Whenever any battle ends with the protoss backing off, an enormous amount of hp is regenerated. 1 stalker could easily regenerate 240 hp in a game, especially if you are using blink effectively. This means that his shields are taking 3 times as much damage as his armor. In this case, the shield upgrade is a far better choice.

The problem is the cost. The armor upgrade is much cheaper and can actually be more useful in certain situations. Against a Terran with any amount of ghosts, I would go with the shield upgrade. If you are planning an early all-in timing push, I would go with the armor, since you are only going to be having one battle and there won't be much regeneration going on. The money saved from doing armor instead of shields could go to reinforcing units.

They are both useful upgrades, so ideally you will be getting both, but it seems that shields is a far more useful one, even considering the high price of the upgrade.

I think that the shield upgrade is good for any micro-oriented opening. I like it with a blink stalker opening against zerg. I drop the forge while i am pushing out.

It really just depends what your game style is. If your going to do a lot of Stalker harass i would probably just get attack upgrades. If you just want map control/defense.. Then I would try out the shield upgrade.

I have always wondered about sheilds and when to get sheilds vs armour. I have recently warmed up to it because of the several benifits that shields have over armour:
1) They affect all units(and buildings too if im not mistaken?)
2) Shields regenerate fast in this game so while armour can only be reduced once, limiting the total number of damage reductions, shields can be reduced multiple times. This is especially important for units like stalkers that have a lot of shields, and lots of mobility to run away. especially blink stalkers!
So if you fight a small army where they only can do enough damage to barely deplete your shields after you have an armour upgrade, then you avoided taking damage that you would have taken without the shield upgrade.
3) The upgrade takes the same time as an armour or weapon upgrade, so to get something that is more powerful than weapon or armour, only one structure is needed.

Basically, if you are going something like a phoenix opening, or blink stalkers where you have to use either really mobile units, or air and ground units, then I recommend going shields instead of armour. For blink stalkers, go just sheilds instead of weapons, because the armour upgrade for stalkers is pitiful.

I only get these in the late game. More of a "be MORE unstoppable" purchase than anything, and since I have the money...

Shield is very rarely worth it.

Almost every unit has more (or equal) amount of armor then shield. Archons are the only exception but because of their gas cost they are basically always mixed with lots of zealots who benefit from armor more. Either way a zealot and archon heavy army should focus on getting 3 attack before even considering lvl 2 armor or a shield upgrade.

Stalkers and mixed ground / air armies benefit decently from shields but those armies don't benefit much from upgrades at all really (so you shouldn't even get a forge early) and they are gas heavy (so you shouldn't be upgrading much). Voidrays and phoenix both have alot more armor then shield so they don't even benefit much from it.

Finally most protoss units have 1 base armor. Armor upgrades are better if they let you go from 1 to 2 instead of from 0 to 1.


The only scenario where getting shield reasonably early is worth considering is when you're playing against mutaling. Muta's divide their damage by nature and do alot of hit and runs. Since their damage is 9 + 3 + 1 and your units most have 1 base armor already an additional armor upgrade will only decrease the damage by 2. A shield upgrade however decreases damage by 3 from muta. Also against muta you will often be using a gateway + phoenix mix so shield also affects your phoenix while armor only affects your ground. I'd still focus on getting 1 and probably 2 ground attack upgrades first in this case but afterwards shield is actually reasonable (if zerg continues to mass air). Cannons, pylons and probes also benefit relatively well from the shield upgrade which is relatively useful vs muta's.

In every other scenario i'd go 3-2 attack & armor first before getting shield.

imo shield should just be reduced to 150/150. In BW there was shield regeneration during combat making shield upgrades slightly better there, in sc2 however shield doesn't regenerate at all during most combat (it just regenerates MUCH faster out of combat) making the upgrade quite crap.

that's what i thought, it's really a lame upgrade


its pretty good for units that have a high shield point value, definitely a little underused but its because attack and armor are 9/10 times better

I think people are underestimating the shield upgrade because there is almost no limit to how much better it can be over the armor upgrade. It's a way you can raise the skill ceiling of your build because each time you save a unit and allow it's shields to regen you are increasing the value of the upgrade, it seems like it would be much better for micro heavy players. It allows harassment to be a little less risky each time, while the armor upgrade requires you to permanently lose HP before you get any value from it. The fact that it works on air, ground, and buildings is also great and makes the shield upgrade the obvious choice if you are going with a gateway/stargate mix. EMPs can make it a waste but that is only one match up.

If
Attack = 50
Shield Armor = 3
Shield HP = 20
HP Armor = 4
HP = 80

Remaining HP = 50 - 3 = 47 vs Shield HP
47 - 20 = 27 Remaining Damage

27 Remaining Damage - 4 HP Armor = 23 Remaining Damage

80 HP - 23 Remaining Damage = 57 Remaining HP

HP Armor is applied if there's still damage, but not together.

If shield upgrades cost the same amount as armor upgrades I believe it would be an obvious choice to upgrade shield before armor - due to the fact that shields can regenerate while armor can not - ignoring the fact that some units have more health than shields.

The fact that shield upgrades effect every single protoss unit and building seems to justify its cost.

I would say shield level 1 research seems to be overlooked but from my analysis, in SC1 shield research at the pro level was rare and it seems as though that trend has spread to SC2.

Then again the mechanic of shield regeneration differers between SC1 and SC2. In sc1 it was a steady tick whilst in SC2 there needs to be a pause of X seconds before shield regeneration starts, but the regeneartion process is orders of magnitude faster than in SC1.
Said another way in SC1 shield regeneration would be akin to zerg auto heal but in SC2 shield regeneration is akin to SCV auto repair.

Zealots have quite a bit more health than shields, and they're going to be the ones tanking the brunt of the initial assault in most battles. Also if you upgrade shields against terran you're going to be (even more) sad when the EMP hits you.
