5 blasts in front of firewarriors
Casting 5 blasts in front of firewarriors (not on – or they’d damage you unless done carefully) will kill them all, whether they’re 1 or 20. Remember to apply animation cancelling: don’t hold ctrl while casting blasts, select blast, cast in front of FWs, then immediately click behind your shaman, cast the next blast, etc. Then you will not take any damage.
Swarm next to building
Swarming next to (not on) a hut or tower will cause the swarm to enter the building and kick whoever’s inside it. When you’re going to attack, first cast ghost army in front of enemy huts to see if there’s firewarriors on them, then use a combination fo ghosts and swarms to take enemy firewarriors out. This way your shaman won’t die when attacking.
Avoiding enemy lightning when reincarnating
When your shaman is dead and an enemy shaman is near your reincarnation site, DON’T try to light her immediately after reincarnating. You’ll probably just die to her lightning, and your lightning will miss. Instead, select blast and click it 10 times every second somewhere outside from the reincarnation site (out of range), and in a safe direction. Your shaman will immediately start moving that way when she reincarnates and if yuo’re clicking fast enough, avoid the lightning in most cases.
When using firewarriors to attack the enemy shaman, align them so each will come from a different direction – the enemy shaman is almost sure to die when you do this. Combine with strategic use of the D key with them selected, and shift+clicking the target right after they’re been blasted to make sure they get a final blast in. When you have just your firewarriors up against the enemy shaman, with this tactic you can ensure you kill her almost every time – should be able to do so nearly every time if you have terrain advantages. When you’re using your shaman and you’re up against just firewarriors, you should be able to apply micro management to kill them all easily. Sometimes you’ll need to go back for a second.
