Now, we all know how to airmine. But do you know how to airmine faster than you are normally allowed? Here's the trick. It all depends on how fast you can hit "C" and clik your mouse. Sound simple? Maybe not as simple as you think. If you notice, whenever you hit "C" you lay an airmine. If you repeatedly hit "C", chances are all you are doing is stacking mines. Now what I want you to do is click your mouse in different parts on the battle screen and hit "C" at about the same time. You will notice that now your alb will move and still lay down a mine. In fact every time you choose a different direction, you basically reset the amount of time between each airmine. It also helps to scatter them over a bigger area.
Make a custom formation so your albs are more spread out than Alt Q so you can spread out more mines and eliminate overlapping and is harder for air to suicide to take out your albs.
I suggest using this technique to cover a large area so that you will effect more units. And then group mines closer together where you really need it.
Use Arbs as a group. Hit the backspace key to select all.
Hold the Ctrl key down and right click in the direction to aim.
With all units still selected hit the B key to Bombard that location.
The attack area markers will show the location you are aiming.
With Arbs sensors are the key. Better sensors give a larger damage area.
If you have a 15m sensor - the damage area will be up to 15m radius from your target area.
Obviously the biggest point of using a support liche is for the use of the IRBM Defence Shield. This blocks not only nukes but more importantly the use of a phaser.
When to use?
Whenever you see a Phaser like an Orbus/Joria/Roc come near a poc immediately put a liche shield as close to the poc as possible. The highest tl shield is 70 so hopefully you have 22+ edu. When deployed that shield will cover about 75% of the length of a screen and the entire width even though the visual is much less than that. The best shield can also be placed away from the liche body more than the other shields, about halfway across the length of the screen from the liche. Only other use for the shield is to block nukes.
By far the most interesting way to block phasing is the put a shield over the units being phased as this works as well.
Equipment
Get cloak, best sensor, best shield, then the best stock. Do NOT pick any gamma nor solar since that 200 energy drain will most likely deplete before the enemy phaser is destroyed, though you can block nukes. Pick the best methane or cell. Last thing you really need is a weapon so I wouldn't equip it.
As with any other support units hotkey the liche to 1 for easy access and keep your finger on the letter D since that's the hotkey for the shield.
I've heard rumors that nukes can slip through the shield, but this is most likely the result of the crappy lowest tl shield that covers an area barely larger than the visual. As far as my use on shields, I've never let a nuke through if it's within the shield effect and I've never seen a phasing get through so I can determine that the effect is constant as long as the shield is activated.
REMEMBER THE SHIELD IS TWO WAY! Just like the orbus shield it will block any ally nukes and will stop allies from phasing to the phaser or from the unit being phased.
Use just one support Redeye as a support unit in a group. Don't use 2 as it'll cut your effectiveness down quite a lot. Use a Redeye to scan if you're hunting to spot where arbs or nukers might be. Scan is always useful for recon against the enemy. The best feature of the Redeye argurably would be the jammer. This will jam the enemy's minimap and they can't see what their allies would see. Much harder for them to communicate and work as a group. Remember that jam takes a lot of energy and that it will last for 4 blip on your minimap.
Laying mines with sappers is mostly a boring task. Try to perfect the in-line laying method. Line up your sappers using one of the formation sets like Alt A that sets your sappers in a line. Mine in areas that can be commonly used by the enemy or to protect your portal. Do NOT mine your allied portals. Mining enemy portals can result in much chaos. Move across the area to be mined by clicking the direction with the mouse and Deploying the mines as you go. This will result in a carpet of mines and achieve maximum damage when triggered. Stacking mines does work on a linear scale 5 mines = 5x damage. Do not mine on allied pocs as anybody sitting defending them while the mines explode can die. There are instances where mining pocs is ok such as when it won't be sat and will be lost soon.
Don't equip a weapon so you can just right click with your spirit to Mindwarp or Shortcircuit the target. This helps if you have a group of units since it won't do anything to your other units unless it can attack the target. Next most important should be the very best sensor you can get. Next equip the cloak, sometimes you can't equip cloak and the best Shortcircuit lest you have 12+ clout. And since your spirit should be your most important unit then put the spirit on 1 so you can switch to it fast and use it in less than a second. To do that then select the spirit only and press Ctrl 1 or put it that way in the deployment screen. For all else look below.
For MindWarp the best to equip would be the H tl 60 gamma collectors but if you plan on using this to mw rapidly and all over the place then use the best cell you can find. To mindwarp always seek the most important most microed target. Obviously this includes the JORIA as the primary target then the Mlortha, Abom/Quorg, or Knell being microed on poc under splash fire. Always use mw as extensively as you can relative to your energy. If you have gamma then keep it handy on any infantry or organic you see nearby.
Since ShortCircuit take so much energy always equip the best cell you can get. ShortCircuit is just as useful in victory maps as mindwarp is. Though your energy may deplete fast, still use it extensively. Your primary targets should be Rocs and Orbus as well as any other support units you can target. Now lest you have the best SC then remember it will fade faster than the MW will so you should actually cast it twice for every one MW (considering you're using the best MW).
Other tips
If you're fast enough you can easily mw/sc any phaser coming your way and eliminate it without them reacting. Hot key them to "1"!
Remember you can't use it instantly after you used it once, there's about a second or so delay between each time you can use a sc/mw so good timing means you can get the most units stopped.
If you see any single spirits on the enemy side then ELIMINATE it as quickly as possible.
