What do you do. Every time my zerg opponent goes mass mutas I get pummelled. How do you stop this? I'm thing psi storm but I never seem to tech it.
Psi Storm would work. Stalkers in big enough numbers would work as well. If you have sentries there too with guardian shield, they'd help a ton. Pheonix's would do the trick too, but you'd need to micro them.
If the amount of mutas is still low like 8-9, blink stalkers are your answer. However, Pheonix is where it is at, since they hard counter mutas so hard with 20 dmg per shot , 1 extra range, faster movement, and move while attacking. Justifies the stargate and the +50 minerals extra cost. Getting the +1 air attack also helps enourmously. It is my preference to use Pheonix's a lot though, since their graviton beam can pick up queens, drones and hydras(which is also weak against pheonix). HT is NOT an answer IMO. takes too long to tech to HT, and research storm. Also most people can't storm moving mutas easily anymore, since they don't stack. In addition, you have to storm their shadow making it even more difficult.
Psi storm sucks against air. What you'll want to use are a bunch of Phoenix units. Shoot while moving around them. Mutas have a low acceleration speed, while Phoenix can shoot while moving, and recharge shields if you back off for a bit. Use that to your advantage.
Phoenix's work, but zerg has the ability to produce lots of units at once, if they want. Protoss can't do that with phoenix's, so you have to consider warping in lots of stalkers. Ideally with blink. If there's enough of them, and your micro is good, templar storm is a great option. When your energy is out on the templars, merge them into archons which are also great against air because they do extra damage vs biological and splash damage. You can park the archons in places where the mutas are sure to attack, like the mineral line, and place cannons there as well. All that being said, if a half dozen mutas come into your base and you don't have anti-air up yet... you've probably already lost.
blink stalkers, easy and low tier unit. Of course this may not be the easiest solution because they aren't designed to easily dispatch mutalisks but they warp in quick, do excellent damage and are cost efficient. Plus they can be used against a handful of other zerg units so they don't lose their usefulness. If you have the luxury of a very strong economy though, you should protect your mineral lines as best as you can though just because mutalisks are fast enough to be able to pop in and out for fast harass.
The best defense against them is to go early phoenixes.They will take command of the air forever,as they are some of the best fighters in the game.Considering you build them early also gives you the numbers you need. If phoenixes doesn't fit your strategy you should go for the stalkers,although they are going to be chasing mutalisk shadows all day without blink,and some good positioning. Another option is to make a couple of photon cannons as support for your moving stalkers.
Usually if you scout you should notice a quick tech or quick expansion (to compensate for the tremendous gas and crystal usage it costs to afford them). If that's the case I would play aggressive to halt his economy and stall his muta's. He needs a lot of resources to mass mutalisks, so if he can only pump a couple out than they are very weak. Zealots would easily counter his early lings. If that fails than I would build both phoenix/stalker (blink upgrade) to combat them. Stalkers can easily escape mutalisk pummeling through blink. They also have a longer range of 6, compared to a mutalisk range of 3. ( I believe). Plus as someone stated earlier, they are more cost effective.
