1 more addition to the macro crystals. Often happens that you Bach just because you don't have time to put obsidian(who knows in the battle on the crystals if they see that you want to blow up, you have to put obsidian in front of a man, then the whole crystal damage absorbed). So, download, bendim, aim the unit, press the 1 button, he goes to obsidian, and is switched to 1 hotkey. A very handy macro. For adequate operation is required to keep the obsidian in 8 hot slot. Good luck
